Important Questions Class 8 Social Science Resources and Development Chapter 2

Geography is the study of the physical features of the planet as well as human impact on certain locations that have shaped both civilisation and the planet. The second chapter of Class 8 Social Science Resources and Development is Land, Soil, Water, Natural Vegetation and Wildlife Resources. The land, type of soil, and water resources in an area often impact the inhabitants’ way of life. The most significant abiotic resources include land, soil, and water, whereas biotic resources include natural flora and wildlife. In the meanwhile, both biotic and abiotic resources are finite. As a result, these resources must be used responsibly to prolong their usefulness. Chapter 2 Class 8 Social Science Resources and Development Important Questions covers these topics. Students can easily access all this and more on the Extramarks website.

Important Questions Class 8 Social Science Resources and Development Chapter 2- with Solutions

The Social Science faculty of Extramarks have documented an entire list of Important Questionnaires Class 8 Social Science Resources and Development Chapter 2 using multiple sources. The land, soil, and water resources of a place usually affect the manner of life of the locals. Land, soil, and water are the most important abiotic resources, whereas biotic resources include natural flora and animals. Both biotic and abiotic resources are limited in nature. . To extend the utility of these resources, they must be handled wisely. These questions and solutions help students better comprehend Land, Soil, Water, Natural Vegetation and Wildlife Resources. 

Some of the Important Questions Class 8 Social Science Resources and Development Chapter 2 and their solutions are mentioned below:

Question 1. Suggest three ways to conserve water.

Answer 1. There are three primary ways to save water:

• Increasing the amount of vegetation, especially in the forest, reduces surface runoff.
• Gathering rainfall to replenish subsurface water.
• Reducing irrigation water loss and switching to less water-intensive agricultural practices.

Question 2. Describe landslides and their effects.

Answer 2. The mass movement of rock, rubble, or soil down a slope is a landslide. Along with volcanoes, earthquakes, and floods, landslides occur. A huge landslide caused by persistent rain might stop the river from flowing for a considerable time. Towns downstream may be destroyed if a river block is created and bursts. Landslides lead to serious tragedy in mountainous areas that frequently cause property damage and loss of life, and they have been a cause of great worry.

Question 3. Which are the two main climatic factors responsible for soil formation?

Answer 3. Temperature and rainfall, which affects the rate of weathering and humus formation, are the two key climatic elements involved in soil formation.

Question 4. Why do you believe that land is a valuable resource?

Answer 4. Since we all need land for living, agriculture, and for creating and building homes, businesses, factories, roads, and bridges, among other things, it is regarded as a valuable resource. It would be difficult for us all to survive without this most precious resource. Land usage is influenced by several physical elements, including the soil, terrain, minerals, climate, and water supply. Human factors like population and technology also influence the land use pattern. People and their needs are always increasing since we know that land is a finite resource.

Question 5. Name two steps the government has taken to conserve plants and animals.

Answer 5. The government took two major steps to preserve and safeguard natural vegetation, wildlife, and plant life are:

• Our native wildlife and plants are protected by national parks, wildlife sanctuaries, and biosphere reserves.
• To preserve forests, a priceless natural resource, awareness campaigns are organised, such as social forestry and tree planting campaigns called “Vanamahotsava.”

Question 6. How can the government preserve the fauna and flora?

Answer 6. The government has taken several steps to preserve flora and animals. Some of these involve building national parks and wildlife refuges, essential for safeguarding plants and animals by giving them a secure natural home. Through initiatives like Vanamahotsava and social forestry, the government has also increased public awareness of the need to protect plants and animals. The government protects the forests on its property by designating them as a natural habitat for flora and wildlife. The government creates a wildlife refuge out of a natural forest for this purpose as no people are permitted to dwell in their ecosystem—these sanctuaries aid in conserving the flora and the fauna.

Question 7. Write any two reasons for land degradation today.

Answer 7. The two primary causes of land degradation are the excessive use of chemical fertilisers and deforestation. The worry of losing this natural resource has been fueled by the expanding population and their constant need, resulting in widespread forest cover and arable land degradation.

Question 8. What are the primary causes of soil degradation?

Answer 8. The biggest threats to the soil as a resource are erosion and soil depletion. Both natural and human-made causes can cause soil erosion. The two main causes of soil erosion and degradation are overgrazing and deforestation. Due to the rising population density and the large-scale deforestation that made land and resources accessible to accommodate the growing population, land degradation is now observed considerably. Another factor contributing to land degradation is the increasing use of fertilisers and chemicals.

Question 9. Why is land considered an important resource?

Answer 9. The land is considered an important resource because it may be used for various purposes such as agriculture, forestry, mining, construction of homes, roads, and the establishment of industries, the land is seen as a valuable resource.

Question 10. How can water be conserved? Give any three methods.

Answer 10. The three methods of water conservation are based on the three Rs, specifically:

• Reduce: Use only as much water as is necessary and avoid wasting any.
• Reuse: You can irrigate your plants with the water left over after washing your veggies, and you can flush the toilet with the water from your washing machine.
• Recycle: Sewage water and effluents must be treated before being discharged into ponds and rivers.

Question 11. State whether the given statement is true or false. If true, write the reasons.

• Ganga-Brahamaputra plain of India is an overpopulated region.

• Water availability per person in India is declining.

• Rows of trees planted in the coastal areas to check the wind movement are called intercropping.
• Human interference and climate change can maintain the ecosystem.

Answer 11. Following are the answers to the true and false:

1. True: Plains and river valleys provide even topography, plain fertile land suitable for farming. As a result, they are crowded with people.
2. True: Freshwater supplies are becoming scarce due to growing urbanisation, population growth, higher standards of living, and increased demand for food and cash crops. Water contamination or drying up water sources are to blame for the shortages.
3. False: Rows of trees are planted to control wind direction and safeguard the soil cover. These are known as shelterbelts.
4. False: Natural habitat loss can lead to ecological collapse due to climate change and human influence.

Question 12. Why do you believe there is less water available in India?

Answer 12. India’s population is steadily increasing, with rising demand for food and cash crops, water pollution, overuse of aquifers and slow recharge.   Besides this, there are no strict policies in place to conserve and reuse water, and as a result, the country’s water supply is decreasing.

Question 13. Why do you believe the Ganga and Brahmaputra basins are densely populated?

Answer 13. India’s Ganga-Brahmaputra plain is overpopulated. This is because even topography and accessibility to high fertility soil, both of which are suitable for the cultivation of crops, draw a sizable population.

Question 14. What climatic factors are involved in the formation of soil?

Answer 14. Temperature and rainfall are the two main climatic elements contributing to soil development. It is impossible to make soil without the presence of these two elements.
