Case Study Questions for Class 8 Social Science Geography Chapter 2 Land, Soil, Water, Natural Vegetation and Wildlife Resources
Here we are providing case study questions for class 8 social science Geography Chapter 2 Land, Soil, Water, Natural Vegetation and Wildlife Resources.
Case Study Question 1:
The thin layer of grainy substance covering the surface of the earth is called soil. It is closely linked to the land. Landforms determine the type of soil. Soil is made up of organic matter, minerals and weathered rocks found on the earth. This happens through the process of weathering. The right mix of minerals and organic matter makes the soil fertile. The major factors of soil formation are the nature of the parent rock and climatic factors. Other factors are the topography, role of organic material and time taken for the composition of soil formation. All these differ from place to place. Soil erosion and depletion are the major threats to the soil as a resource. Both human and natural factors can lead to the degradation of soils. Factors which lead to soil degradation are deforestation, overgrazing, overuse of chemical fertilisers or pesticides, rain wash, landslides and floods. Landslides are simply defined as the mass movement of rock, debris or earth down a slope. They often take place in conjunction with earthquakes, floods and volcanoes. A prolonged spell of rainfall can cause heavy landslides that can block the flow of rivers for quite some time. The formation of river blocks can cause havoc to the settlements downstream on its bursting. In the hilly terrain, landslides have been a major and widely spread natural disaster that often strike life and property and occupy a position of major concern.
Q. 1. Which is the most appropriate method to check the soil erosion on steep slopes?
(a) Shelter belts
(b) Mulching
(c) Soil texture
(d) Terrace cultivation
Ans. Option (d) is correct.
Explanation: Broad flat steps or terraces are made on the steep slopes so that flat surfaces are available to grow crops. They reduce surface runoff and soil erosion.
Q.2. refers to the destruction of soil by wind and water.
(a) Soil erosion
(b) Landslides
(c) Land degradation
(d) None of these
Ans. Option (a) is correct.
Explanation: Soil erosion and depletion are the major threats to soil as a resource. Both human and natural factors can lead to the degradation of soils. It refers to the destruction of soil by wind and water.
Q. 3. Which determines the type of soil?
(a) Landforms
(b) Soil erosion
(c) Land degradation
(d) None of these
Ans. Option (a) is correct.
Explanation: The thin layer of grainy substance covering the surface of the earth is called soil. It is closely linked to land. Landforms determine the type of soil.
Q. 4. Soil is made up of:
(a) Matter
(b) Material
(c) Matter, material and weathered rocks
(d) None of these
Ans. Option (c) is correct.
Explanation: Soil is made up of organic matter, minerals and weathered rocks found on the earth. This happens through the process of weathering. The right mix of minerals and organic matter makes the soil fertile.
Q. 5. The method in which rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
(a) Mulching
(b) Rock dam
(c) Terrace cultivation
(d) Inter cropping
Ans. Option (b) is correct.
Explanation: Rock dam: Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
Learning Outcomes
- Understand the importance of resources in our life.
- Appreciate the judicious use of resources for sustainable development.
- Develop awareness towards resource conservation.
- Take initiative towards the conservation process.
Important Keywords
- Landslides: The sudden fall of
mass of earth, rock, etc., down the side of the mountain.
- Parent Rock: The original rock from which a particular soil is formed is known as its parent rock.
- Water Cycle: The natural process of the constant motion of water by evaporation, condensation and rainfall is known as the water cycle.
- Rain Water Harvesting: This is the process of conservation of water under which rainwater is collected so that it can be used in times of water scarcity.
- Biosphere: It is the narrow zone of contact between the lithosphere, hydrosphere and atmosphere.
- Tundra: The type of vegetation found in extremely cold regions such as the Arctic.
- Scavenger: A bird or animal, which derives food from dead livestock.
- National Parks: A natural area dedicated to protect the ecological integrity of ecosystem(s) for the present and future generations.
- Vanamohatasava: The social programme of planting trees organised at community level.
- Biosphere Reserves: Series of protected areas linked by a global network, which demonstrate the relationship between conservation and development.
- Wildlife Sanctuaries: This is similar to a national park, but it aims at the protection of a particular animal or general wildlife.

What is Case Study Question in Class 8 Social Science?
Case study questions typically present a specific scenario or case related to a historical event, geographical issue, or social problem. Students are expected to read and understand the details of the case and then answer a set of questions based on their understanding and knowledge of the subject matter.
Case study questions can be an effective way to assess students’ understanding and ability to apply social science concepts to practical situations. They also encourage students to think critically, analyze information, and draw informed conclusions – skills that are valuable both inside and outside the classroom.
