Selina Concise Solutions for ICSE Class 6 Geography Chapter 3 Major Landforms of the Earth

POINTS TO REMEMBER
- Nearly 29 per cent of earth's surface is land.
- Land features on the surface of the earth are different in different places. These features are called landforms. The major landforms include mountains, plateaux, valleys and plains.
- There are three main types of mountains - fold mountains, volcanic mountains and block mountains.
- There are two types of fold mountains - old and young.
- Plateaux are also called plains-in-the air or tablelands.
- Plains are flat lowlands that are mostly built by the alluvium deposited by rivers.
Landforms are the natural shapes and features found on the Earth's surface, like giant puzzles made of rock and soil. These shapes are formed over millions of years by forces coming from both inside and outside the Earth.
Teacher's Tip: Think of landforms as the Earth's "sculptures" carved by nature.
Exam Tip: Always mention the four major landforms (mountains, plateaus, valleys, and plains) when defining the term.

IMPORTANT TERMS
Fold mountains: Mountains that are formed when horizontal layers of the earth's crust are folded by compression.
Landforms: Features of the land surface.
Compression is like pushing two ends of a rug together until the middle rises up in waves or folds. These landforms give us a clue about how powerful the movements deep inside the Earth can be.
Teacher's Tip: Remember "Fold" sounds like folding paper; that is exactly what the Earth's crust does!
Exam Tip: In definitions, use keywords like "compression" for fold mountains to get full marks.

Discuss

Question : Formation of landforms is a continuous process. Discuss the different ways in which landforms are changing around the world.
Answer:
The earth's surface is constantly changing. These changes mostly occur in very minute ways which over time accumulates to create the earth's physical features. Whereas some of these changes take thousands of years but surely they are occuring. We look around us that a mountain, river, plateau, valleys, rqck boulders etc. these all didn't just disappear suddenly rather most of them had a building process.
There are basically two types of changes that occur on the earth's surface.
1. Slow change
2. Fast change.
Fast change occur through the actions of earthquakes, volcanoes, landslides etc. While slow change takes time and has a process.
Landforms are never static because the Earth is always active internally and externally through weather. While we see fast changes like volcanoes immediately, the slow movement of tectonic plates builds mountains over eons.
Teacher's Tip: Imagine the Earth as a living thing that is slowly growing and changing its shape every single day.
Exam Tip: Divide your answer into "Slow Change" and "Fast Change" headings to make it clear for the examiner.

VALUES AND LIFE SKILLS

Question : We constantly impact landforms around us by our actions such has mining, building roads, dams, etc. We should, therefore, try to minimize such activities that have an adverse impact on landforms around us.
How can you help to preserve the landforms around you?
Answer:
We can preserve the landforms around us by adopting following methods, and they are:
1. By Planting More Trees and Not cutting them.
2. By Properly Disposing the Industrial waste.
3. By Preserving greenery surrounding, National Parks and Wildlife Sancturies.
4. Avoid de-vegetating the landforms and its Vicinity, if that's it's natural condition.
5. Replicate Natural landscapes, patterns and processes.
Human activities like construction and mining can cause erosion and destroy the natural beauty of the land. By protecting the environment, we ensure that these beautiful landforms remain stable and healthy for future generations.
Teacher's Tip: Remember the "Green Earth" rule: more plants mean less soil erosion and stronger landforms.
Exam Tip: List preservation points in a numbered format to ensure each idea is clearly seen and graded.

EXERCISES

A. Match the columns
A - B
1. the Appalachians - (i) low-lying lands between hills or mountains
2. vent - (ii) old fold mountains in North America
3. faulting - (iii) the opening through which lava comes to the surface
4. valleys - (iv) the rupturing or fracturing of rock strata due to strain
Answer:
A - B
1. the Appalachians - (ii) old fold mountains in North America
2. vent - (iii) the opening through which lava comes to the surface
3. faulting - (iv) the rupturing or fracturing of rock strata due to strain
4. valleys - (i) low-lying lands between hills or mountains
Matching these terms helps us understand how specific geographic features are classified and how they function. For example, knowing that a vent is an opening for lava helps us identify volcanic activity.
Teacher's Tip: Associate "vent" with "ventilation" or an exit point to remember it is an opening.
Exam Tip: Draw straight lines or rewrite the pairs clearly to avoid confusion during matching questions.

B. With the help of your atlas identify and mark the following in an outline map of the world.

Question 1: An old fold mountain range in India.
Answer:
Aravallis
The Aravallis are among the oldest mountain ranges in the world and have been worn down by weather over millions of years. They run through the western part of India, mainly in Rajasthan.
Teacher's Tip: Aravallis starts with 'A', just like "Ancient" - helping you remember they are old fold mountains.
Exam Tip: When marking on a map, use a specific symbol like a series of small triangles ^^^ to represent mountain ranges.

Question 2: A block mountain in Europe
Answer:
The Black Forest of Europe.
Block mountains are formed when large areas are broken and displaced vertically. The Black Forest in Germany is a famous example of this type of mountain structure.
Teacher's Tip: Think of "Black" and "Block" - they sound similar, which helps you link the Black Forest to block mountains.
Exam Tip: Always mention the country or continent (Germany/Europe) to show a complete geographical understanding.

Question 3: A storehouse of mineral wealth in eastern India.
Answer:
The Chota Nagpur Plateau.
This region is incredibly rich in minerals like coal and iron ore, which are essential for many industries. It is often called the "mineral heart" of India due to its vast resources.
Teacher's Tip: Visualize a "Chota" (small) box that is actually a giant treasure chest of minerals.
Exam Tip: Use the term "storehouse" in your answer to echo the question's phrasing for a stronger response.

Question 4: A rift valley in Egypt
Answer:
Nile Valley in Egypt.
Rift valleys are formed when the land between two faults sinks down. The Nile Valley is a perfect example of how water flows through these sunken areas of the crust.
Teacher's Tip: "Nile" and "Valley" are often used together in history; just remember the Nile is a rift valley feature.
Exam Tip: Ensure you spell "Rift" correctly, as it refers to a specific geological fracture.

C. Answer the following questions in brief

Question 1: What are Fold Mountains? With the help of a neat-sketch, briefly explain their formation.
Answer:
The mountains that are formed when the layers of the earth's crust are folded by compression caused by the forces generated by movements inside the earth. [Refer to diagrams showing "Layers of the earth's crust" and "Compression of the crust leads to the formation of fold mountains"]
There are particularly two types of fold mountains, they are:
1. Old fold mountains
2. Young fold mountains.
Fold mountains are like the wrinkles on the Earth's skin caused by plates pushing against each other. These ranges contain some of the highest peaks in the world, like the Himalayas.
Teacher's Tip: Think of a tablecloth being pushed across a table - the ridges it forms are like fold mountains.
Exam Tip: When asked for a sketch, always label the "Compression" arrows to show the direction of force.

Question 2: State two chief differences between old and young fold mountains. Give examples.
Answer:
The mountains which were formed over 250 million years ago due to compression of earth's crust are called old fold mountains. They have gentle slopes and low altitude due to weathering overtime e.g. Urals in Russia, Aravallis in India and Appalachians in India [North America].
The recently formed mountains i.e. about 25 million years ago are called young fold mountains. They are rugged and lofty. They comprise the world's highest mountain ranges.
E.g. Rockies of North America, Alps, Andes, Himalayas and The great Dividing Range.
Young mountains are tall and pointy because they haven't been eroded much yet, while old ones are shorter and rounder. This difference in height and shape tells us how long they have been standing against the wind and rain.
Teacher's Tip: "Young" mountains are like sharp teenagers (lofty and rugged), while "Old" mountains are like rounded grandparents (gentle and low).
Exam Tip: Create a T-chart to compare the two types; it is easier for the teacher to read and gives you a better score.

Question 3: What are plateaux? Why are they of great economic value?
Answer:
Plateaux (plural of plateau) are the uplifted sections of the earth's crust that are almost flat or level and usually descend steeply to the surrounding lowlands. A plateau is also sometimes referred to as a plain-in-the air or tableland. The land of a plateau is very fertile while the latter is a storehouse of mineral wealth. They are rich in minerals like gold, iron, copper, manganese, etc.
Plateaus are special because they provide both flat ground for living and deep layers of precious minerals. Their unique "tabletop" shape makes them look like high islands of land rising above the plains.
Teacher's Tip: Think of a "Plateau" as a giant "Plate" raised up on a table.
Exam Tip: Mention specific minerals like gold or iron to demonstrate the "economic value" part of the question.

Question 4: Mention the different types of plateaux.
Answer:
Types of Plateaux - Plateaus may be classified into the following categories on the basis of their formation, appearance and location:
Tectonic Plateau: A tectonic plateau is formed by the movement of the earth's crustal plates. Tectonic movement causes a huge portion of the earth's surface to rise. The plateau of South Africa and the Turkish-Iranian Plateau are examples of tectonic plateaus.
Volcanic Plateau: A volcanic plateau is a plateau formed by the spread of successive layers of lava on a particular region. When the lava cools, it solidifies and the successive sheets of lava finally form a raised tabeland or a plateau over a period of time. The extensive Columbia Plateau (in the north-western part of the U SA), the north western part of the Deccan Plateau and the Malwa Plateau are examples of volcanic plateaus.
Dissected Plateau: These have irregular surface marked by canyons, gorges and steep, narrow valleys formed by the process of erosion. They are mostly common in dry and desert regions. The Colorado Plateau, through which the Grand Canyon passes, and the Brazilian Plateau (Mato Grosso) are examples of dissected plateaus.
Intermontane Plateau: These are surrounded by mountains and are the most common types of plateau. The most common example of an intermontane plateau is the Tibetan Plateau which is enclosed by the Himalayan Mountains to its south and the Kunlun Shan to its north.
Piedmont Plateau: Piedmont plateau is one that lies between a mountain and a plain or an ocean. Examples of piedmont plateaus are the Patagonia Plateau in South America and the piedmont Plateau of North America.
Each type of plateau is defined by how it was created, such as by lava flows or by being surrounded by tall mountains. This variety shows us that different geological forces can result in similar flat-topped landforms.
Teacher's Tip: "Inter-montane" means "between mountains" - the name itself tells you the definition!
Exam Tip: When listing types, give one specific example for each to show you've studied the atlas thoroughly.

Question 5: What is a basin? Give an example.
Answer:
A basin is a depressed section of the earth's crust surrounded by higher land. Many basins are found alongside plateau edges and form areas of inland drainage, i.e., the rivers flowing in the basin do not reach reach the sea. The Tarim and Tsaidam Basins of Asia and the Chad Basin of north-central Africa are examples of basin.
Basins act like giant bowls in the landscape where water collects and sometimes disappears into the ground. Because they are lower than the land around them, they are key areas for drainage.
Teacher's Tip: Compare a geological basin to your bathroom washbasin; it's lower in the middle to collect water.
Exam Tip: Remember to mention "inland drainage" as a key feature of many basins.

Question 6: Mention the different types of plains.
Answer:
Types of Plains: On the basis of formation, plains are grouped in three categories:
Structural Plains: Plains that lie near the coast of a sea or an ocean are called structural plains. Due to endogenetic movements, large, broad, flat areas of the sea floor are raised and appear on the surface. These types of plains are very flat and broad. The addition of sediments brought in by the sea waves over a period of time makes them broader and flatter than they originally were. Structural plains border all countries. The coastal plains of south-eastern USA near the Gulf Coast, which are part of the Great Plains, are one of the largest plains in the world. The plains of northern Russia and the central lowlands of Australia are other examples of structural plains.
Erosional Plains: Erosional plains are the result of the erosion of mountains, hills and plateaux. The eroded material is brought down to a low level by wind, rivers, rain, and ice. This kind of erosion caused by various agents gives rise to several types of plains. The plains of northern Canada, northern Europe and Kashmir in India are examples such plains.
Depositional Plains: Depositional plains are formed by sediments brought down on a large scale by natural agents such as moving ice, water and wind from the upper regions of mountains.
Plains are formed in different ways, from the rising of the sea floor to the wearing down of mountains. They are usually the most level areas on Earth, making them very important for human activity.
Teacher's Tip: Remember "Erosional" comes from "Erode" (wear away) and "Depositional" comes from "Deposit" (put down).
Exam Tip: Be sure to distinguish between these three types based on the 'process' of their formation.

Question 7: What is the importance of plains?
Answer:
The importance of the plains are discussed below:
1. Plains are important because they are good source of fresh fruits and vegetables.
2. Plains are being ploughed by a farmer or a carabaos.
3. Owing to the flat nature of the land. It is easy to construct roads and railways in plains.
4. Plains have good and rich source of river which is very fertile for crops.
Plains are the most populated landforms because their flat surface makes it very easy for humans to build and travel. The fertile soil brought by rivers also makes them the best places for growing food.
Teacher's Tip: Plains = Prosperity; they provide the food and transport we need to thrive.
Exam Tip: Use the term "Fertile soil" to explain why farming is so successful in plains.

Question 8: What is a peninsula? Take the help of your atlas and name four major peninsulas of the world.
Answer:
A Peninsula is a piece of land that is surrounded by water on three sides and joined to a larger land mass. The peninsular plateau of India and the Malay Peninsula are two examples of peninsulas attached to the continent of Asia. Europe is a peninsula of peninsulas. Can you name the three large water bodies that surround it? Also identify the smaller peninsulas that jut out from it. Arabian peninsula, Deccan for major peninsula are peninsulas, Indo-China peninsula, Alaska peninsula.
A peninsula is like a finger of land pointing out into the ocean, connected to the mainland at only one side. This unique shape often makes these regions important for trade and sea travel.
Teacher's Tip: Think of India's shape - it's a perfect "V" surrounded by water, which is a classic peninsula.
Exam Tip: Don't confuse a peninsula with an island; remember the "three sides of water" rule.

Question 9: Which two land masses does the Isthmus of Panama connect?
Answer:
The Isthmus of Panama joins North America and South America with the Pacific Ocean on one side and the Atlantic Ocean on the other. The Isthmus of Suez joins Africa to Asia and separates the Mediterranean Sea and the Red Sea.
An isthmus acts as a thin bridge connecting two massive continents together. Without these narrow strips of land, the continents would be completely separated by water.
Teacher's Tip: Think of an Isthmus as a "neck" of land connecting the "head" and "body" of continents.
Exam Tip: Mention both the land masses and the surrounding water bodies for a complete geographical description.

D. Answer the following questions in one or two paragraphs:

Question 1: Name the major landforms on earth.
Answer:
The major landforms on earth are:
- Mountains: Most of the rivers originate from mountains. They are rich in minerals and metals deposits and support variety of flora and fauna.
- Plateau: They are storehouses of minerals such as gold, silver, iron, copper, manganese, etc.
- Valley: They are low-lying lands between hills formed by river flowing down the mountains or due to movement of earth plates.
- Plains: They are the most fertile landforms which support easy habitation.
Each landform has its own unique characteristics and provides different resources for humans and animals. Understanding these helps us see how diverse our planet's surface truly is.
Teacher's Tip: Remember the "Big Four": Mountains (tall), Plateaus (flat-top), Valleys (low), and Plains (flat).
Exam Tip: Briefly explain one feature of each landform to show you understand their differences.

Question 2: List the continents according to size. Describe the two largest continents in detail.
Answer:
Continents are very large land masses that are surrounded by vast water bodies called oceans on all sides. They are the primary divisions of land. There are seven continents in the world.
Asia is the largest continent. It occupies about one-third of the land area of our planet. It is joined to the land mass of Europe and, thus, we use the term Eurasia for this combined land mass. The Ural Mountains, the Black Sea and the Caspian Sea separate the two continents. We find oceans on three sides of this land mass. To its north lies the Arctic Ocean, to its east is the Pacific Ocean and to its south is the Indian Ocean.
Africa is the second largest continent after Asia. It is surrounded by water bodies on all sides. In the north, the Mediterranean Sea separates it from Europe, and on its east is the Indian Ocean. The Atlantic Ocean in the west separates it from the two Americas. In Africa lies the largest desert of the world, the Sahara Desert.
Continents are the foundation of our world's geography, hosting different climates, cultures, and species. Asia and Africa together cover a huge portion of the Earth's total land area.
Teacher's Tip: Use the acronym AS-AF-NA-SA-AN-EU-AU to remember continents from largest to smallest.
Exam Tip: Include major physical features like "Sahara Desert" or "Ural Mountains" when describing specific continents.

Question 3: Write short notes on: 1. Europe 2. Australia.
Answer:
1. Europe is smaller in size in comparison to the other continents mentioned above but has some of the most developed nations in the world. To its north is the Arctic Ocean. The Atlantic Ocean separates it from North America. It has the most indented coastline among the continents, which is why it has numerous ports and some of the finest harbours in the world.
2. Australia is sometimes called 'the Land Down Under' as it lies to the south of the main land masses. It is also the smallest continent in size. As there is water on all sides - the Indian Ocean in the west, the South Pacific Ocean in the east, the Southern Ocean in the south, and the Arafura Sea in the north - it is an island and is, therefore, also called the 'island continent'.
Europe is known for its complex coastline, while Australia is unique as it is both a continent and an island. Both have distinct locations that have shaped their history and economy.
Teacher's Tip: Europe is the "Port King" because of its wiggly coastline, and Australia is the "Island Continent".
Exam Tip: Mention Australia's nickname "The Land Down Under" to show extra knowledge.

Question 4: How is Mount Fuji of Japan different from the Vosges of Europe?
Answer:
Mount Fuji is a volcanic mountain formed when molten lava, ash, dust, etc. come out through cracks in earth's crust and is accumulated in shape of high cone. Whereas Vosges in Europe are formed by rupturing or fracturing of rock strata due to strain and is an example of block mountain.
The main difference lies in their origin: one was built by fire and lava, while the other was built by the breaking of the Earth's crust. This results in very different shapes, with Fuji being a cone and Vosges being a blocky ridge.
Teacher's Tip: "Volcano" = "Fuji" (lava buildup) vs "Block" = "Vosges" (crust snapping).
Exam Tip: Use the phrase "mode of formation" to explain the difference scientifically.

Question 5: Briefly describe the importance of mountains.
Answer:
Importance of Mountains:
1. Mountains are a storehouse of water. Many rivers originate in the glaciers in the mountains.
2. Reservoirs are made and the water from the mountains is used for irrigation and generation of hydro-electricity.
3. The river valleys and terraces are most suitable for farming and cultivation of crops as the land is very fertile.
4. Mountains support a rich variety of flora and fauna.
5. Mountains also affect the climate of an area. For example, the Himalayas cause rainfall in India by blocking the south-west monsoon winds. They also protect us from the cold winds of Central Asia in winter.
6. Mountains are also rich in mineral and metal deposits which are essential for industries.
7. According to the United Nations Development Programme, mountains provide home for around 720 million people.
8. The forests in the mountainous regions provide fuel, fodder, shelter and other products like gum, wild fruits, mushrooms, resins, etc. mountains provide an ideal holiday for tourists. They visit the for their natural scenic beauty and relaxation.
9. Many recreation, sporting and tourism activities takes place in the mountains. Paragliding, hang gliding, river rafting and skiing are popular sports in the mountains.
Mountains are not just beautiful; they are life-givers that provide water, influence weather, and offer resources for survival. They act as natural barriers and hubs for biodiversity and tourism.
Teacher's Tip: Think of mountains as "Water Towers" of the world because of glaciers.
Exam Tip: If asked for "importance," try to list points like water, minerals, and climate impact to get full credit.

Question 6: How is a volcanic mountain formed?
Answer:
Volcanic mountains are formed when molten lava, ash, cinder and dust from deep inside the earth come out on the surface through cracks in the earth's crust and accumulate in the shape of high cones.
The opening through which lava and other materials come to the surface is called a vent. The funnel-shaped depression at the top of a vent is called a crater.
Examples - Mountain Fujiyama in Japan, Mountain Mayon in the Philippines.
As layer upon layer of cooled lava builds up, the mountain grows higher and takes on its iconic cone shape. It is a landform literally built from the inside of our planet bursting out.
Teacher's Tip: Visualize a wax candle dripping; as the wax piles up, it forms a shape like a volcanic mountain.
Exam Tip: Always define "vent" and "crater" when explaining volcanic mountains.

Question 7: What is a V-shaped valley?
Answer:
The valley which is formed by an exogenous process i.e. from the outside like a river flowing down the mountain eroding the soil and minerals form a V-shaped valley, eg. Rhine valley in Europe and Damodar valley in India.
A river acts like a knife, cutting deep into the rock as it flows swiftly down a slope. Over time, this constant erosion creates the distinctive "V" profile in the landscape.
Teacher's Tip: The "V" shape is narrow at the bottom because the river is still cutting down into the ground.
Exam Tip: Mention that "exogenous" means forces acting from the outside of the Earth.

Question 8: Briefly explain 1. peninsula 2. island 3. isthumus.
Answer:
1. Peninsula: is a piece of land that is surrounded by water on three sides and joined to a larger land mass. The peninsular plateau of India and the Malay Peninsula are two examples of peninsulas attached to the continent of Asia. Europe is a peninsula of peninsulas. Arabian peninsula, Deccan for major peninsula are peninsulas, Indo-China peninsula, Alaska peninsula and Labrador peninsula.
2. Island: An island is a piece of land which is surrounded on all sides by water. India has two groups of islands - the Lakshadweep Islands in the Arabian Sea and the Andaman and Nicobar Islands in the Bay of Bengal.
3. Isthumus: An isthmus is an elongated narrow piece of land, with water on each side, that joins two large land masses. For example, the Isthmus of Panama joins North America and South America with the Pacific Ocean on one side and the Atlantic Ocean on the other. The Isthmus of Suez joins Africa to Asia and separates the Mediterranean Sea and the Red Sea.
These terms describe the relationship between land and water. Whether land is totally surrounded by water or connected by a narrow bridge, these shapes define our world's borders.
Teacher's Tip: Island = 4 sides water; Peninsula = 3 sides water; Isthmus = Bridge of land.
Exam Tip: Give a specific Indian example (like Lakshadweep) to show your local geography knowledge.

E. Draw neat, labelled, coloured sketches to show the characteristics of each of the following geographical features. Write a brief description alongside, explaining each of them

Question 1: Block mountain
Answer:
Block mountain - They are formed by rupturing or fracturing of rock strata due to strain. The land between the cracks inside the earth sink leaving upstanding blocks on either side making mountains. [Refer to diagram with labels: Subsidence, Uplift, Rift valley, Block mountains. "Block mountains are formed due to sinking of the adjacent land."]
When parts of the Earth's crust move up or down along a crack, it creates steep, block-like mountains. This process is like a giant elevator system where some blocks of land go up and others go down.
Teacher's Tip: Think of a chocolate bar being snapped; the pieces that stay up are the block mountains.
Exam Tip: Label the "sinking" arrows clearly in your drawing to show subsidence.

Question 2: Volcanic mountain
Answer:
Volcanic mountain - They are built when molten lava, ash, cinder and dust from deep inside the earth comes out on the surface through cracks in the earth's crust and accumulate in the shape of high cones. The opening through which lava and other materials come to the surface is called a vent. The funnel-shaped depression at the top of a vent is called a crater. [Refer to diagram with labels: Gases and ash, Crater, Vent, Lava, Crust, Mantle, Magma Chamber]
Volcanoes are the Earth's way of releasing heat and pressure from deep within the mantle. The resulting cone shape is a pile of cooled material that has erupted over thousands of years.
Teacher's Tip: Don't forget to draw the "Magma Chamber" deep underground in your diagram.
Exam Tip: Use different colors for lava (red) and ash (grey) to make your sketch stand out.

Question 3: Plateau
Answer:
Plateau - It is the uplifted section of the earth's crust that are almost flat or level and usually descend steeply to the surrounding lowlands, eg. Deccan Plateau and the Chota Nagpur plateau etc. [Refer to photograph showing a flat-topped elevated landform]
A plateau is often very high up but lacks the sharp peaks of a mountain. This makes them unique because they provide a stable, flat surface at high altitudes.
Teacher's Tip: Draw a plateau with a very flat top and very steep sides to show the "table" effect.
Exam Tip: Mention the "steep slopes" or "cliffs" as a key identifying feature.

Question 4: Rift valley
Answer:
Rift Valley - The rift valley is the type of valley that is formed when the land between the two faults sink i.e. the land between 2 block mountains is called rift valley. [Refer to diagram showing "Subsidence" and "Rift valley" between block mountains]
As the ground sinks between two faults, it creates a long, narrow trough or valley. Many major rivers find their path through these natural depressions in the crust.
Teacher's Tip: Think of a rift valley as the "floor" between two "walls" of block mountains.
Exam Tip: Use the word "subsidence" to describe the sinking part of the rift valley formation.

F. Picture study

Look at the photographs of a plain and a plateau given here and answer the questions.

Question 1: How does a plain look different from a plateau?
Answer:
A plain is a flat piece of land where it is very easy to build houses, roads and carry agricultural practices whereas a plateau is a flat raised piece of land with steep slopes and high cliffs from the surrounding land which makes the soil rich in minerals like iron, copper, manganese.
The main visual difference is height; a plain is low and open, while a plateau is high and looks like a platform. Plains are smoother, whereas plateaus often have jagged edges called cliffs.
Teacher's Tip: A plain is like the floor; a plateau is like a table standing on that floor.
Exam Tip: Focus on the height and the slopes when comparing these two landforms.

Question 2: Why are river plains thickly populated?
Answer:
The river plains are thickly populated as it is easier to make buildings, construct roads and have all kinds of transportation facilities. The land is also very fertile, rich in minerals. Thus, making it easier for people to grow crops for their living.
People live in plains because the land is gentle on their feet and provides plenty of food. Water from the rivers also ensures that life and trade can flourish easily.
Teacher's Tip: Rivers + Flat Land = The perfect recipe for a big city!
Exam Tip: Mention "transportation" and "fertility" as the two main reasons for high population density.

Question 3: How is life in the plains different from life in the mountains?
Answer:
Landforms also influence weather. The higher one goes the colder it gets, while down in the plains and valleys it is warmer. Since landforms affect climate they also affect farming. It is more difficult to grow crops and rear cattle on hillsides than it is in the plains. In the plains, it is easier for people to make roads and houses and to dig wells, unlike in the mountains where it is difficult and expensive to make them and water has to be brought from distant streams. In other words, life in the mountains is more difficult than life in the plains.
Mountains present a physical challenge with their steep slopes and cold temperatures. In contrast, the plains provide a much more comfortable environment with easy access to water and space.
Teacher's Tip: Life in mountains is like a constant workout; life in plains is like an easy walk.
Exam Tip: Contrast the two based on climate, construction ease, and water availability.
