i. A collage is a piece of art which is by pasting various materials such as photographs and pieces of paper on a chart or a similar backing.

ii. In other words, it is a form of art that involves beautifully gathering pictures and words.

iii. For example, by collecting different images of the mountain landscape, a collage can be created beautifully. The photographs or images can be placed in geometric shapes or even in a random way.

(Students can attempt this question by finding pictures of different landscapes like beaches, mountains, historical places, wildlife sanctuaries, etc., and pasting them to create a collage). 


17. How will you observe that the destruction of trees affects the soil?

Ans: The effects of the destruction of trees on soil can be observed by the following method:

i. Firstly the required materials need to be collected: three small food cans, one big can with holes made in the bottom, twelve coins, and soil. These things can easily be arranged at home or school with the help of a parent or teacher. 

ii. In the next step, the three small cans need to be filled with soil to the top.

iii. Then four coins need to be kept on the soil of every can. 

iv. After filling the cans with holes with water, water is to be sprinkled on the three cans. 

v. The sprinkling of water is to be done at different rates for different cans – slow for the first can, moderate for the second can, and heavy for the third can. 

These are all the steps that we need to carry out to conclude this experiment, the water sprinkled represents rainfall while the coins represent tree covers. As a result of sprinkling water, the unprotected soil splashes out and this occurrence is maximum in the can experiencing heavy water sprinkling or the ‘regions experiencing high rainfall’. It is also observed that the tree covers or the ‘coins’ in this case try to prevent the splashing out of the soil.  Lands that are devoid of vegetation or tree covers will have their soil disappear quickly. Hence, by this simple experiment, anyone can observe how the destruction of trees affects the soil. This activity will help the students in learning that deforestation or the destruction of forests is not good as it will result in the depletion of the soil.


18. Why are the rainforests depleting?

Ans: The rainforests are depleting because of the underlying issues:

i. In the rainforests, developmental activities are going at a fast speed, and the indigenous population is being pushed out, therefore resulting in its depletion.

ii. The deforestation or destruction of the rainforests has adverse impacts on a very large scale. Two of such impacts are the washing away of the topsoil turning the landscape barren. 


19. How is tourism an important activity in the Ganga Brahmaputra plain?

Ans: Tourism is an important activity in the Ganga Brahmaputra plain due to the 

The Ganga-Brahmaputra plain is rich in natural resources. This region has seen the evolution of humans and from past to present major cities have developed in these basins. Due to the development of major cities, there are many such sites which have become famous for some reasons and are now famous tourist attractions. Some of such places include —

i. Historical and ancient sites like the Taj Mahal of Agra, Buddhists stupas in Uttar Pradesh and Bihar, the Imambara in Lucknow, etc.

ii. There are hilly areas of the Ganga Brahmaputra basin rich with scenic places. Mountains and waterfalls are the most scenic places to visit in these areas. For example, many tourists visit the hilly tracts of Arunachal Pradesh to witness its rich tribal culture. 

iii. There are many forested areas rich in wildlife. For example, the Manas and Kaziranga wildlife sanctuaries of Assam. 

iv. There are many holy and cultural sites here where people visit. Example – Varanasi. 

These famous tourist destinations have made tourism an important activity in the Ganga Brahmaputra plain.


20. Discuss about the people living in the rainforests.

Ans: The life of people living in rainforests can be elaborated as follows:

i. The people living in the rainforest live a very miserable life as compared to the people living in other places. 

ii. People grow their crops in very small areas by clearing the trees of the rainforest.

iii. The women practice ‘slash and burn agriculture’ agriculture to grow crops like pineapple, sweet potato, tapioca, and cash crops such as maize, coffee, cocoa. 

iv. The men are mainly engaged in hunting.

v. The staple food of these people is manioc which is a potato-like crop that grows inside the earth.

vi. Queen ants and their eggs are also eaten by them. 

vii. Some people live in thatched houses while some people reside in large houses called ‘maloca’.

viii. With the increasing accessibility of the rainforests by outside people, the lives of these indigenous people have become more difficult. They are pushed out from their native areas and have migrated to new surrounding areas.

FAQs on CBSE Important Questions for Class 7 Social Science Human Environment Interactions - 2025-26

1. What are the most important reasons for the depletion of rainforests as discussed in CBSE Class 7 Social Science Chapter 6?

The depletion of rainforests is a critical topic for exams. The primary reasons as per the 2025-26 syllabus include:

  • Developmental Activities: Large-scale projects, like the construction of the Trans-Amazon highway, have made previously inaccessible parts of the forest reachable for exploitation.
  • Industrialisation: Forests are cleared to set up industries and for extensive mining operations.
  • Agriculture: Large patches of forest are cleared for farming, both through 'slash and burn' agriculture by indigenous populations and for large commercial farms.
  • Lumbering: The high demand for wood in global markets leads to widespread and often illegal cutting of trees.
  • Soil Erosion: Once the protective tree cover is removed, the topsoil is easily washed away by heavy rains, turning lush green forests into barren landscapes.

2. Explain the key geographical factors that make the Ganga-Brahmaputra plains suitable for paddy cultivation.

The Ganga-Brahmaputra plains are highly suitable for growing paddy due to a combination of favourable factors:

  • Fertile Soil: The rivers deposit rich, alluvial soil every year, which is ideal for agriculture and reduces the need for artificial fertilisers.
  • Sufficient Water: The region receives adequate rainfall from the monsoons, and the presence of numerous rivers provides water for irrigation throughout the year.
  • Flat Topography: The plains have a gentle slope, which is perfect for developing canal irrigation and for the cultivation of rice.
  • Favourable Climate: The area has high temperatures and high humidity during the monsoon season, which are essential for the growth of paddy.
  • Abundant Labour: Being one of the most densely populated areas in the world, there is a large supply of inexpensive labour available for farming activities.

3. Describe the lifestyle and agricultural practices of the people living in the Amazon rainforests.

The people of the Amazon rainforests have a lifestyle uniquely adapted to the environment. Men typically engage in hunting and fishing in the rivers, while women are responsible for the crops. They primarily practise 'slash and burn' agriculture. In this method, a patch of forest is cleared by cutting and burning the trees. Crops are then grown in this clearing for a few years until the soil loses its fertility. The main crops grown include tapioca, pineapple, and sweet potato, with manioc (also known as cassava) being a staple food. They live in large, thatched-roof houses called 'Maloca', which have steeply slanting roofs to allow rainwater to run off.

4. How is the fauna of the Amazon Basin different from that of the Ganga-Brahmaputra Basin?

The fauna in the two basins are distinct due to major differences in climate, vegetation, and geography.

  • Amazon Basin: It is famous for its incredible biodiversity. It is home to exotic birds like toucans and hummingbirds with brightly coloured plumage, and animals like monkeys, sloths, and ant-eating tapirs. The rivers are filled with thousands of species, including the flesh-eating piranha fish and giant snakes like the anaconda.
  • Ganga-Brahmaputra Basin: The fauna here is adapted to a monsoon climate and riverine plains. Common animals include elephants, deer, and monkeys. The delta area is the natural habitat of the famous Bengal tiger and crocodiles. The rivers are home to aquatic life like the endangered freshwater Ganges River Dolphin.

5. Why are the Ganga-Brahmaputra plains one of the most densely populated regions in the world?

The Ganga-Brahmaputra plains support a high population density primarily due to factors that favour human settlement and agriculture. The fertile alluvial soil, deposited annually by the rivers, supports intensive agriculture that can feed a large population. The flat terrain makes it easy to build transport networks, industries, and settlements. A reliable water supply from the rivers and monsoon rains further supports both farming and daily life, making it an ideal and sustainable place for human habitation for thousands of years.

6. What are some expected long-answer questions from 'Human Environment Interactions' for the 2025-26 exams?

For the 2025-26 exams, students should focus on comparative and descriptive long-answer questions from this chapter. Key expected questions often involve:

  • A detailed comparison of the life, climate, and vegetation in the Amazon Basin versus the Ganga-Brahmaputra Basin.
  • An explanation of how developmental activities are leading to the destruction and degradation of the Amazon rainforest.
  • A description of the main features of the Ganga-Brahmaputra basin, including its topography, major crops, and unique wildlife like the Bengal Tiger and one-horned rhinoceros.

7. How can map-based questions be framed from this chapter in the Class 7 Social Science exam?

This chapter is ideal for map-based questions. For the exam, you might be asked to:

  • Locate and Label: On an outline map of the world or a specific continent, identify and mark the Amazon River and its basin, or the Ganga and Brahmaputra rivers and their delta.
  • Shade Regions: You could be asked to shade the area covered by the Amazon rainforest or the densely populated northern plains of India.
  • Identify Features: A map might point to a specific location like the Sundarbans, and you would be asked to name the famous animal found there (e.g., Bengal Tiger).

8. What is the importance of cash crops in the Amazon and Ganga-Brahmaputra basins?

Cash crops are crops grown for sale in the market rather than for the farmer's own use, and they are vital to the economies of both regions.

  • In the Amazon Basin, people grow cash crops like coffee, maize, and cocoa, which contribute to the local economy.
  • In the Ganga-Brahmaputra Basin, important cash crops include jute, tea, and sugarcane. Tea is famously grown on the slopes in Assam and West Bengal, while jute cultivation is significant in the delta region. These crops are crucial for trade and employment.
