Voyage Solutions for ICSE Class 6 Geography Chapter 11 South America Climate Natural Vegetation Wildlife Mineral And Power Resources

POINTS TO REMEMBER

1. The climate of South America is influenced by its location, presence of the Andes Mountains, prevailing winds, nearness to seas and oceans, and the impact of ocean currents.
2. The vast continent of South America has a climate that varies from the equatorial climate in most of Brazil, to the desert climate of the Atacama and Patagonian Deserts.
3. Some areas of Venezuela, Guyana, and Brazil also experience tropical climate. There is a small stretch of central Chile which experiences Mediterranean climate. Southern Chile has a maritime climate.
4. Different climates have influenced the natural vegetation found in South America. Forests exist in areas that receive heavy rainfall throughout the year such as the equatorial forests of the Amazon Basin. Grasslands predominate in regions that record maximum rainfall during the summers such as the grasslands in Guyana and Brazil. Deserts exist in areas that receive hardly any rainfall such as the Atacama and Patagonian Deserts. Mountain vegetation grows in the Andes and Mediterranean vegetation is found in central Chile.
5. The wildlife of South America includes several unusual species such as the anaconda, birds such as the egret, rhea, and condor, and animals such as the guanaco, vicuna, and llama.
6. Hardwood trees like mahogany, rosewood, and rubber are found in the selvas. Brazil nuts, balsa, cinchona for quinine, gum, resins, and dyes are other products obtained from these forests. Yerba mate is an important tree that grows in the Eastern Highlands.
7. Rivers like the Amazon, Orinoco, and Parana provide inland water transport. Brazil, Argentina, Paraguay, and Venezuela have developed hydroelectric power projects.
8. South America is rich in minerals ranging from crude oil, copper, diamond, gold to silver. This is what attracted the Europeans to settle in this continent.

Exam Tip: Remember to associate "Quinine" with "Cinchona" and "Malaria."

Question 8: Chile leads in the production of copper.

Answer:
Chile. The country possesses some of the largest copper reserves on the planet, particularly in the Atacama region. Copper mining is the backbone of the Chilean economy.
Teacher's Tip: Think of the thin, long shape of Chile as a "copper wire" on the map.
Exam Tip: Chile is the world's top producer, so use this fact for any question about South American minerals.

B. Find the odd one out in each of the following groups and say why.

Question 1: Llanos, pampas, campos, selvas

Answer:
Selvas - As all other are grass. Selvas are dense, tropical rainforests with many layers of trees. The other three terms refer to different types of open grasslands found across the continent.
Teacher's Tip: Think of "Grass" versus "Trees" to solve this puzzle.
Exam Tip: When explaining "why," always mention the category the other items belong to.

Question 2: Rubber, cinchona, pine, ebony

Answer:
Pine. Pine is a softwood tree typically found in cooler or temperate climates. The other trees listed are all hardwoods found in tropical rainforest environments.
Teacher's Tip: Most rainforest trees have broad leaves, while pines have needles.
Exam Tip: Distinguish between "hardwood" and "softwood" categories in your reasoning.

Question 3: Tapir, piranha, sloth, puma

Answer:
Tapir, pranha - piranha is a reptile. (Textbook Note: Piranhas are actually fish, but the textbook answer provides this classification). The other animals in the list are land-dwelling mammals found in the forests or mountains. They represent the diverse terrestrial fauna of the continent.
Teacher's Tip: Look at where the animals live: water versus land.
Exam Tip: Even if you know a biological fact is different, stick to your textbook's categorization for exams.

Question 4: Jaguar, vicuna, llama, alpaca

Answer:
Jaguar - These three belong to camel family. The vicuna, llama, and alpaca are related species used for wool and transport in the Andes. The jaguar is a large predatory cat and the top carnivore of the rainforest.
Teacher's Tip: The Jaguar is a hunter, while the others are gentle plant-eaters.
Exam Tip: Mention the "Camel family" relationship for the three similar animals.

Question 5: Cactus, pine, scrub, prickly pear

Answer:
Pine. Pine trees belong to mountain or temperate forest zones. The other three types of vegetation are xerophytes specifically adapted to survive in dry desert conditions.

This matching exercise connects specific geographical regions with their characteristic plant life. Understanding these links helps visualize the physical landscape of the entire continent.
Teacher's Tip: Use the "elimination method" by matching the ones you are 100% sure of first.
Exam Tip: Write the numbers and letters clearly in a side-by-side format for easy checking.

D. Answer the following questions in brief.

Question 1: How does the shape of the continent affect the climate of th£ southern part of South America ?

Answer:
Due to its tapering size or shape, the southern part of South America gets the moderating influence of the oceans and thus has mild climate. Because the land narrows down, the surrounding cold and warm currents can easily reach the interior regions. This prevents the southern part from experiencing extreme continental temperatures.
Teacher's Tip: "Tapering" means the land gets narrower at the bottom like a funnel.
Exam Tip: Use the term "maritime influence" to describe the effect of the ocean on land climate.

Question 2: Mention some of the factors that affect the climate of South America.

Answer:
A large part of South America lies within the tropical zone and is, therefore, hot. The apparent movement of the sun has an impact on die climate of South America. The climate is, however, r also influenced by a number of other factors such as the presence of the Andes Mountains, the height of a place above sea level, prevailing winds, nearness to seas and oceans, and die impact of ocean currents such as die warm Brazilian Current and the cold Peru Current. These factors work together to create a wide variety of environments from frozen peaks to steaming jungles. Ocean currents are particularly important as they can make coastal areas either very wet or very dry.
Teacher's Tip: Remember: L-A-M-P (Latitude, Altitude, Mountain barriers, Proximity to sea).
Exam Tip: Listing at least four factors like "latitude," "altitude," "winds," and "ocean currents" will get full marks.

Question 3: Name the summer and winter months in large parts of South America.

Answer:
As it is mainly located in the southern hemisphere, a very large part of South America experiences summer in December and early January and winter in June-July. Because it is south of the equator, its seasons are the exact opposite of the seasons in the Northern Hemisphere. This means while we might have winter, they are enjoying their warmest weather.
Teacher's Tip: Just flip the calendar in your head: Northern Winter = Southern Summer!
Exam Tip: Mention the "Southern Hemisphere" to explain why the months are different from our seasons.

Question 4: Which winds bring heavy rainfall to the Guiana Highlands and Brazil?

Answer:
The North-east and South-east Trade Winds bring heavy rain to the Guiana Highlands and Brazil. These permanent winds pick up moisture as they travel across the warm Atlantic Ocean. When they hit the land and rising highlands, they release this moisture as heavy tropical rainfall.
Teacher's Tip: Trade winds are like "water carriers" from the ocean to the land.
Exam Tip: Specify both "North-east" and "South-east" directions for the trade winds.

Question 5: Why is the Atacama a desert? Is it a tropical desert or a temperate desert?

Answer:
The Northern and central Andes block North East and South East Trade Winds which bring rain from the Atlantic Ocean to the Guiana Highlands and Brazil. Therefore, the regions west of the Andes do not receive any rain and are very dry and hot and the Atacama Desert is located here. The Atacama is a tropical desert. The mountains create a "rain shadow" effect where all the moisture falls on one side, leaving the other side completely dry. Additionally, the cold Peru Current along the coast further prevents any rainfall from forming.
Teacher's Tip: Think of the Andes as a giant "umbrella" that keeps the Atacama perfectly dry.
Exam Tip: Always categorize Atacama as a "tropical desert" based on its latitude.

Question 6: Name some of the forest resources from the selvas of South America.

Answer:
The selvas or equatorial forests are important for hardwood trees such as mahogany, rosewood, and rubber. The camaiiba palm tree yields wax, which is used for making shoe polish, furniture polish, lipstick, and candles. The bark of the cinchona tree yeild quinine, a medicine used for treating malaria. Balsa, which is a lightweight wood, Brazil nus, gum, resins, and dyes are other products obtained from selvas. These forests are incredible storehouses of raw materials that are used in industries all over the world. Many of these resources, like rubber and medicine, were first discovered by indigenous people living in these forests.
Teacher's Tip: The rainforest is like a "natural supermarket" filled with useful items.
Exam Tip: Group your answer into categories like "wood," "medicines," and "industrial products" for clarity.

E. Answer the following questions in one or two paragraphs.

Question 1: Quito is located near the equator yet it has a cool pleasant climate throughout the year. Explain.

Answer:
Quito is the capital of Ecuador. It is situated close to the equator. In spite of its equatorial location, it has a pleasant climate throughout the year as it is situated high in the Andes. This proves that altitude is just as important as latitude when determining how warm a place will be. Even at the equator, if you go high enough into the mountains, you will find spring-like temperatures all year round.
Teacher's Tip: Think: Higher the altitude, cooler the temperature!
Exam Tip: Mention that altitude overrides the equatorial heat to create "eternal spring" conditions.

Question 2: Briefly describe the vegetation and wildlife of the selvas.

Answer:
The selvas or equatorial forests are important for hardwood trees such as mahogany, rosewood, and rubber. The camauba palm tree yields wax, which is used for making shoe polish, furniture polish, lipstick, and candles. The bark of the cinchona tree yields quinine, a medicine used for treating malaria. Balsa, which is a lightweight wood, Brazil nuts, gum, resins, and dyes are other products obtained from selvas. Yerba mate is an important tree of the Eastern Highlands. The leaves of this tree are used to make a tea-like beverage. The Gran Chaco region grows quebracho (the woid - quebracho - means - axe-breaker -), a hardwood tree which is a source of tannic acid used in leather tanning. The eastern slopes of the Andes and the confierous forests of Chile have softwood trees, which are important sources of Wood pulp for the paper industry. Colourful birds, monkeys, insects and snakes such as the python and anaconda, reptiles such as crocodiles and alligators and fishes including the piranha are found in the Amazon forests. The selvas are characterized by high tree density and multi-layered vegetation that supports an incredible variety of life. The warm, wet climate creates the perfect environment for this rich ecosystem to thrive without a dormant season.
Teacher's Tip: The "Selvas" are the "lungs of the world" because they are so thick with trees.
Exam Tip: Be sure to include both plant life (mahogany, rubber) and animal life (anaconda, piranha) for a complete "describe" answer.

Question 3: What do you know about the tropical grasslands of South America.

Answer:
These grasslands have long grasses and are known as the llanos in Guyana and the campos in Brazil. There are scattered trees between the grasses of varying heights. These regions experience a seasonal climate with a distinct rainy summer and a dry winter. The tall, coarse grasses are adapted to these changing moisture levels throughout the year.
Teacher's Tip: Tropical grasslands are like a savanna - mostly grass with some brave trees!
Exam Tip: Name both "Llanos" and "Campos" to show you know the different regional names.

Question 4: Describe the temperate grasslands of South America.

Answer:
These are called the pampas in north-eastern and central Argentina and Uruguay. The vegetation consists of short, soft, and nutritious grasses. This is a fertile tree-less area which is well suited to cattle grazing, dairying, and wheat cultivation. Vast amounts of wheat are grown here for export. The mild climate and rich soil make the Pampas one of the "breadbaskets" of the world. It is the heart of Argentina's agricultural industry.
Teacher's Tip: Pampas = Short grass; Llanos = Tall grass. Know the difference!
Exam Tip: Mention "wheat cultivation" and "cattle grazing" as the primary uses of this land.

Question 5: What kind of wildlife can be found in the Amazon forests?

Answer:
Colourful birds, monkeys, insects and snakes such as the python and anaconda, reptiles such as crocodiles and alligators and fishes including the piranha are found in the Amazon forests. This region has the highest number of animal species on Earth, many of which live in the treetops. From tiny poison dart frogs to giant river otters, the biodiversity here is truly unmatched.
Teacher's Tip: The Amazon is like a giant, wild zoo with no cages!
Exam Tip: Use specific names like "Anaconda" and "Piranha" to make your answer more detailed.

Question 6: South America has rich mineral reserves. Write a brief description of the chief mineral deposits.

Answer:
Brazil has one of the world’s largest deposits of iron ore and also has some coal and vast oil reserves. Lake Maracaibo in Venezuela has rich deposits of mineral oil. This makes up for the lack of coal. About $15$ per cent of the world’s crude oil comes from this region of South America. Venezuela is the biggest exporter of oil in South America and is next only to the Arab countries. It is a member of the Organization of Petroleum Exporting Countries (OPEC). Chile is the world’s leading producer of copper. The largest copper mine in the world is at Chuquicamata in northern Chile. Peru is another important copper producer in South America. The Atacama Desert is still rich in nitrates, which are important for making fertilizers. Bolivia is one of the leading countries in tin production in the world. Gold is found in Colombia, Brazil, Ecuador, and Peru. Bolivia and Peru have silver mines. Reserves of two rare minerals - platinum and vanadium - are found in the Andes. Bauxite is mined in Guyana and Suriname. South America is rich in minerals ranging from crude oil, copper, diamond, gold to silver. This is what attracted the Europeans to settle in this continent. The continent's geology provides it with a huge variety of valuable resources that drive its economy. These mineral exports link South America to global manufacturing industries.
Teacher's Tip: Venezuela for Oil, Chile for Copper, and Brazil for Iron - remember this trio!
Exam Tip: Mentioning "OPEC" in relation to Venezuela shows a high level of geographical knowledge.
