Q1. What is the main term for the clearing of forests by humans?
• Afforestation
• Deforestation
• Desertification
• Reforestation
Answer: Deforestation
Deforestation is the process of clearing forests by cutting down trees. This is often done to use the land for agriculture, housing, or industries, leading to a loss of habitat and biodiversity.
Q2. Which of the following is a major consequence of deforestation?
• Increased groundwater level
• Decreased soil erosion
• Global warming
• Increased rainfall
Answer: Global warming
Trees absorb carbon dioxide. When forests are cut down, the level of this greenhouse gas increases in the atmosphere, contributing to global warming and climate change.
Q3. What is the process called when fertile land becomes desert-like?
• Deforestation
• Reforestation
• Desertification
• Conservation
Answer: Desertification
Desertification is the degradation of land in arid and semi-arid areas, often caused by deforestation, overgrazing, and poor farming practices, turning fertile land into desert.
Q4. What type of vegetation is found in the alpine regions of Jammu & Kashmir?
• Dense tropical trees
• Xerophytic plants
• Alpine meadows and shrubs
• Thorny bushes
Answer: Alpine meadows and shrubs
Alpine vegetation in J&K, found at high altitudes, includes grasses, herbs, and small shrubs that are adapted to survive cold temperatures and a short growing season.
Q5. What is the primary cause of soil erosion?
• Planting more trees
• Removal of topsoil by wind or water
• Increased organic matter
• Building terraces
Answer: Removal of topsoil by wind or water
Soil erosion is the removal of the fertile top layer of soil. Deforestation exposes the soil, making it easy for wind and water to carry this valuable layer away.
Q6. Which of these is a protected area where animals are protected from disturbance?
• Deforested area
• Agricultural field
• Sanctuary
• Urban park
Answer: Sanctuary
A sanctuary is a protected area where wild animals can live in their natural habitat without being hunted or facing major human interference. Their habitat is protected.

Q10. The main purpose of establishing a wildlife sanctuary is to:
• Promote hunting
• Protect endangered species and their habitat
• Convert forest to farmland
• Harvest timber
Answer: Protect endangered species and their habitat
Sanctuaries aim to provide a safe environment for wildlife, especially endangered species, by protecting their natural habitat from destruction, poaching, and other threats.
Q11. What is a major cause of deforestation in forests?
• Declining human population
• Large-scale planting of trees
• Clearing land for agriculture and settlements
• Decreasing demand for wood
Answer: Clearing land for agriculture and settlements
A growing human population requires more land for growing food and building homes and cities. This often leads to the clearing of vast areas of forest.
Q12. What is the process of planting trees in an area where forest was destroyed called?
• Deforestation
• Desertification
• Reforestation
• Conservation
Answer: Reforestation
Reforestation is the natural or intentional restocking of existing forests that have been depleted. Planting trees helps restore ecosystems and combat deforestation’s effects.
Q13. Overgrazing by livestock can lead to:
• Increased forest cover
• Improved soil fertility
• Desertification
• More biodiversity
Answer: Desertification
When animals graze too heavily on vegetation, the plant cover is removed. This exposes the soil to erosion, reduces its quality, and can turn the area into a desert over time.
Q14. Which of these is a consequence of deforestation on wildlife?
• Increase in habitat
• Stable climate
• Loss of habitat
• More availability of food
Answer: Loss of habitat
Forests are home to countless species. Cutting down trees destroys the places where animals live, breed, and find food, leading to population decline and extinction.
Q15. What type of protected area allows limited human activity and protects entire ecosystems?
• Sanctuary
• National Park
• Agricultural land
• Mining area
Answer: National Park
National Parks are protected areas of greater ecological significance. They conserve entire ecosystems (plants, animals, landscapes) and allow very limited human activity for recreation and education.
Q16. What happens to carbon dioxide levels when large-scale deforestation occurs?
• They decrease
• They remain the same
• They increase
• They disappear
Answer: They increase
Forests act as carbon sinks, absorbing CO2. With fewer trees, less CO2 is absorbed, and burning during deforestation releases more, increasing atmospheric CO2 levels.
Q17. Which region in J&K is known for its temperate coniferous forests?
