6. Distinguish between renewable and non-renewable resources? (3 marks)
Ans. Renewable resources are those that can be naturally replenished over time, such as sunlight, wind, and water. They are sustainable and typically have minimal environmental impact.
Non-renewable resources, on the other hand, are finite and cannot be readily replaced within a human lifespan, like fossil fuels and minerals. Their extraction and use contribute to environmental degradation and climate change.
7. Why is soil considered as an important resource? (2 marks)
Ans. Soil is crucial for agriculture, providing nutrients for plant growth, supporting biodiversity, regulating water flow, and storing carbon. It's essential for food production and ecosystem health
8. Explain the importance of the conservation of resources. (3 marks)
Ans. Conservation of resources is crucial for sustaining ecosystems, preserving biodiversity, and ensuring future generations' well-being. It helps maintain ecological balance, prevents resource depletion, and mitigates environmental degradation. By conserving resources like water, energy, and forests, we safeguard essential services provided by nature, such as clean air and water. Conservation efforts also promote sustainable development, reducing our ecological footprint and fostering resilience against environmental challenges.
9. How do rocks play an important role in the formation of soil? (3 marks)
Ans. Rocks play a crucial role in soil formation through weathering processes. Physical weathering breaks rocks into smaller pieces, increasing surface area for chemical weathering. Chemical weathering alters rock composition, releasing minerals that contribute to soil fertility. Over time, these processes create a mix of organic and inorganic materials, forming the foundation for soil development essential for plant growth and ecosystem health.
10. What is the gross cropped area and what is contour ploughing? (3 marks)
Ans. The gross cropped area refers to the total land area under cultivation for agricultural purposes, including all crops grown during a particular period within a specified area. Contour ploughing is a farming technique where plowing is done parallel to the contours of the land, rather than in straight lines up and down slopes. This method helps to prevent soil erosion by slowing down the flow of water and allowing it to infiltrate into the soil, reducing the risk of runoff and soil loss.
11. Explain the classification of resources on the basis of exhaustibility. (5 marks)
Ans. Resources can be classified based on their exhaustibility into renewable and non-renewable resources. Renewable resources, like solar and wind energy, can be naturally replenished over time, making them essentially inexhaustible on human timescales. On the other hand, non-renewable resources, such as fossil fuels and minerals, are finite and will eventually be depleted as they cannot be replaced within a human lifespan. This classification is crucial for sustainable resource management and planning, as it highlights the importance of conserving non-renewable resources and investing in renewable alternatives to ensure long-term environmental and economic stability.
12. Distinguish between red soil and laterite soil stating any three points of distinction? (5 marks)
Ans. Here are three points of distinction between red soil and laterite soil:
Composition and colour:
• Red soil is formed from the weathering of crystalline rocks like granite and gneiss. It derives its name from the high concentration of iron oxide, which gives it a reddish appearance.
• Laterite soil forms from the leaching of silica and other soluble materials, leaving behind a concentration of iron oxides and aluminum hydroxides. It typically appears reddish-brown in color.
Texture and Structure:
• Red soil usually has a well-defined structure with good drainage due to its coarse texture. It's often sandy or loamy.
• Laterite soil tends to be hard when dry and can become sticky when wet. It has a relatively poor structure, making it less fertile for agriculture.
Fertility and Nutrient Content:
• Red soil is generally more fertile compared to laterite soil. It contains moderate levels of nutrients, including iron and aluminum oxides, which support the growth of various crops.
• Laterite soil is often nutrient-poor and acidic. Its nutrient content tends to be lower, and it may require significant amendments for agriculture.
13. Which soil is called ‘regular soil'? Mention any four characteristics of this type of soil.(5 marks)
Ans. Regur soil is also known as black soil. Here are four characteristics of regular soil:
Color: Regur soil is dark black in color due to its high content of organic matter and iron oxide.
Texture: It has a fine-grained texture, which means it has good moisture retention properties and is easy to plow.
Composition: Regular soil is rich in minerals like calcium, magnesium, and potassium, making it fertile for agriculture.
Expansion and Contraction: One distinctive feature of regular soil is its ability to swell when wet and shrink when dry, which can lead to the formation of deep cracks in the soil during dry seasons. This characteristic can affect farming practices and irrigation techniques.
14. What is the role of human beings in the development of a resource? (2 marks)
Ans. Humans play a pivotal role in resource development through exploration, extraction, refinement, and utilization, shaping its accessibility, sustainability, and impact on ecosystems and societies.
15. Why is soil considered as an important resource? (2 marks)
Ans. Soil is crucial for agriculture, providing nutrients for plant growth, supporting biodiversity, regulating water flow, and storing carbon. It's essential for food production and ecosystem health.
16. What is the gross cropped area and what is contour ploughing? (3 marks)
Ans. The gross cropped area refers to the total land area under cultivation for agricultural purposes, including all crops grown during a particular period within a specified area. Contour ploughing is a farming technique where plowing is done parallel to the contours of the land, rather than in straight lines up and down slopes. This method helps to prevent soil erosion by slowing down the flow of water and allowing it to infiltrate into the soil, reducing the risk of runoff and soil loss.
17. What are the biotic and abiotic resources? Give some examples. (2 marks)
Ans. Biotic resource:
(i) These are resources that are obtained from the biosphere
(ii) These resources have life
(iii) Examples are plants, animals, fish, human
beings, livestock etc.
Abiotic resource:
(i) These resources are composed of non-living things
(ii) Examples are water, minerals, metals, wind, solar energy etc.
18. Name three states having black soil and the crop which is mainly grown in it? (2 marks)
Ans. Maharashtra, Gujarat and Madhya Pradesh are the names of three states where the cotton is grown.
19. What steps can be taken to control soil erosion in the hilly areas? (2 marks)
Ans. The main techniques that can be used are given below.
(i) Contour ploughing
(ii) Terrace farming
(iii) Strips of grass are allowed to grow between the crops, this method is known as strip cropping.
20. Read the information below and answer the questions that follow. Energy is a basic requirement for economic development. Every sector of the national economy-agriculture, industry, transport, commercial and domestic-needs inputs of energy. The economic development plans implemented since Independence necessarily required increasing amounts of energy to remain operational. As a result, consumption of energy in all forms has been steadily rising all over the country. In this background, there is an urgent need to develop a sustainable path of energy development.
Promotion of energy conservation and increased use of renewable energy sources are the twin planks of sustainable energy. India is presently one of the least energy efficient countries in the world. We have to adopt a cautious approach for the judicious use of our limited energy resources. For example, as concerned citizens we can do our bit by using public transport systems instead of individual vehicles; switching off electricity when not in use, using powersaving devices and using non-conventional sources of energy. After all, “energy saved is energy produced”. (4 marks)
(i) How will using public transport systems instead of individual vehicles help us?
Ans. Using public transport systems instead of individual vehicles helps us in saving energy.
(ii) There is an urgent need for development.
Ans. Sustainability is the urgent need of development
(iii) Meaning of sustainable:
Ans. Viable is the meaning of sustainable
(iv) What is considered to be the basic requirement of economic development?
Ans. Resources, Energy and Technology are the basic requirement of economic development
