Answer: (b) Thematic map. A thematic map shows one particular theme, such as forests, rainfall or population.

Teacher's Note:
1. Physical maps show natural features, political maps show boundaries, and thematic maps show one special subject.
2. Ask yourself what the map is about; if it is about one topic like forests, it is thematic.

Answer: (b) Asia. It is the largest of the seven continents in area and population.

Teacher's Note:
1. Remember the order of size: Asia, Africa, North America, South America, Antarctica, Europe, Australia.
2. Do not confuse the largest continent with the largest country.

Answer: (b) Sarpanch. The Sarpanch is elected by the members of the Gram Sabha to lead the Gram Panchayat.

1. The Panchs are the ward members, while the Sarpanch is the head.
2. Zila Parishad is a body at the district level, not a person.

Answer: (a) Both A and R are true and R is the correct explanation of A. Internal processes (such as folding and earthquakes) and external processes (such as weathering and erosion) keep shaping the surface, which creates many different landforms.

Teacher's Note:
1. First check each statement separately, then ask whether R really explains A.
2. Think of mountains built by internal forces and valleys cut by rivers as examples of the two processes.

Teacher's Note:
1. Panchayat elections are held every five years.

Answer: 1. Fold mountains: formed when the Earth's crust is folded by internal forces, e.g. the Himalayas.
2. Block mountains: formed when large blocks of land are raised or lowered between cracks (faults).
3. Volcanic mountains: formed when lava and ash pile up around a volcano, e.g. Mount Fuji.

Teacher's Note:
1. Name each type and give one example so that the answer is complete.
2. Do not forget that mountains are also grouped by how they are formed, not by height alone.

Answer: 1. The plains are made of fertile alluvial soil brought by rivers like the Ganga and the Indus, so farming gives good crops.
2. Water is easily available from perennial rivers for drinking and irrigation.
3. The land is flat, so it is easy to build houses, roads, railways and towns.
So the Northern Plains are one of the most densely populated regions.

Teacher's Note:
1. Cover soil, water and flat land as the three main reasons.
2. Avoid writing only that there are many people; explain why they settle there.

Answer: 1. It collects taxes such as property tax (on houses and buildings) and water tax.
2. It collects fees and charges for services such as licences, markets and parking.
3. It receives grants and funds from the State and Central governments.
This money is used for roads, water supply, drainage, sanitation and street lights.

1. Think of the three sources: taxes, fees and government grants.
2. Add one line on how the money is used to earn the full marks.

Answer: The troposphere, the stratosphere, the mesosphere, the thermosphere and the exosphere.

Teacher's Note:
1. Copy the names in order from the Earth's surface upward.
2. A quick way to remember them is to count five layers.

Answer: Mainly nitrogen (78%) and oxygen (21%); the remaining 1% is carbon dioxide, argon and other gases.

Teacher's Note:
1. Mention the main gases along with their percentages.
2. Nitrogen is the larger part, though we breathe oxygen.

Answer: The troposphere.

Teacher's Note:
1. The passage lists the layers starting from the Earth's surface, so the first one is the answer.
2. Weather such as clouds and rain occurs in this layer.

Answer: Carbon dioxide absorbs the heat radiated by the Earth and keeps the planet warm. It is also essential for the growth of plants.

Teacher's Note:
1. Give both reasons that the passage mentions.
2. Do not say that carbon dioxide is the gas we breathe; that is oxygen.
