Deforestation and Land Degradation Questions
What is the primary cause of land degradation in coal mining areas?
-
Deforestation
-
Soil erosion
-
Subsidence
-
Acidification
C
Correct answer
Explanation
Subsidence, the sinking of land due to underground mining, is a major cause of land degradation in coal mining areas.
The Tragedy of the Commons refers to the problem of:
-
Overuse of common resources leading to their depletion
-
Pollution of the environment due to industrial activities
-
Deforestation caused by agricultural expansion
-
Climate change resulting from greenhouse gas emissions
A
Correct answer
Explanation
The Tragedy of the Commons highlights the challenge of managing shared resources without proper regulations.
What is the primary cause of deforestation globally?
-
Natural disasters
-
Agricultural expansion
-
Urbanization
-
Mining and extraction
B
Correct answer
Explanation
Agricultural expansion, particularly for large-scale commercial farming, is the leading cause of deforestation worldwide.
Which of the following is a direct consequence of deforestation?
-
Increased biodiversity
-
Enhanced soil fertility
-
Reduced carbon sequestration
-
Improved water quality
C
Correct answer
Explanation
Deforestation results in the loss of forests, which are crucial for carbon sequestration and storage. This leads to an increase in greenhouse gas emissions and contributes to climate change.
How does deforestation impact water cycles?
-
It increases water retention in the soil.
-
It enhances groundwater recharge.
-
It reduces the risk of flooding.
-
It disrupts local and regional weather patterns.
D
Correct answer
Explanation
Deforestation can alter local and regional weather patterns by affecting the water cycle. It can lead to changes in precipitation patterns, increased temperatures, and more frequent and severe droughts.
Which of the following is a major driver of deforestation in tropical regions?
-
Urbanization
-
Mining
-
Commercial agriculture
-
Industrial development
C
Correct answer
Explanation
Commercial agriculture, particularly the expansion of large-scale plantations for crops like palm oil and soybeans, is a major driver of deforestation in tropical regions.
Which of the following is not a major environmental issue facing the Himalayas?
-
Climate change
-
Deforestation
-
Overgrazing
-
Pollution
D
Correct answer
Explanation
Pollution is not a major environmental issue facing the Himalayas.
Which of the following is not a major environmental issue facing the Himalayas?
-
Climate change
-
Deforestation
-
Overgrazing
-
Pollution
D
Correct answer
Explanation

What is the primary cause of soil erosion in India?
-
Deforestation
-
Overgrazing
-
Intensive Agriculture
-
All of the above
D
Correct answer
Explanation
Deforestation, overgrazing, and intensive agriculture are all major causes of soil erosion in India. These activities remove vegetation cover, which exposes the soil to wind and water erosion.
-
The permanent removal of trees from a forest
-
The temporary removal of trees from a forest
-
The selective removal of trees from a forest
-
The natural death of trees in a forest
A
Correct answer
Explanation
Deforestation is the permanent removal of trees from a forest, resulting in a loss of forest cover.
