4. Give reasons.

(i) The rainforests are depleting.

Answer: (i) There was a time when the green belt of rainforests covered about 12-14% of Earth’s land surface. Large-scale developmental activities have led to the clearing of large tracts of land in the rainforests (for example, clearing of land for agriculture, cattle pasture, wood, mining and road building). Today, the rainforests cover only about 2-6% of the Earth’s land surface. Due to constant deforestation, the top soil which is held together by the trees gets washed away as the rains fall. As a result, the once lush green forests change into barren landscapes.

(ii) Paddy is grown in the Ganga-Brahmaputra plains.

Answer: (ii) The Ganga-Brahmaputra plains provide flat, fertile land for the cultivation of crops. The amount of rainfall in this region is also quite high, which makes it a suitable place for the growth of paddy a crop that requires sufficient water.

5. Map skills.

(i) On an outline map of Indian Sub-continent, draw the rivers Ganga and Brahmaputra from the source to the mouth. Also show the important tributaries of both the rivers.

(ii) On the political map of the South America, draw the equator. Mark the countries located on the equator.

6. For fun.

Make a collage to show places of attractions in India. You can divide the class in different groups to show attractions based on mountain landscapes, coastal beaches, wildlife sanctuaries and places of historical importance.

7. Activity.

Collect under mentioned material and observe how destruction of trees effect the soil cover.

Material

(i) Three small flowerpots or food cans (e.g., cold drinks tin cans),

(ii) one big can with holes punched in the bottom (this will act as a sprinkling can),

(iii) twelve coins or bottle caps

(iv) soil.

Process

Take three small cans or pots. Fill them with soil till the top. Press the soil to make it level with the top of the can. Now put four coins or bottle caps on the soil of each can. Take the big can that has been punched with holes and fill it with water. You can also take the sprinkling can from your garden. Now, sprinkle water on the three cans. On the first can sprinkle water very slowly so that no soil splashes out. Let moderate amount of water be sprinkled on the second can. On the third can, sprinkle the water heavily. You will observe that unprotected soil splashes out. Where the ‘rain’ is heavy the amount of soil that splashes out is the maximum and least in case of the first can. The coins or caps represent the tree covers. It is clear that if the land is cleared completely of the vegetation, the soil cover will quickly disappear.
