Deforestation and Land Degradation Questions
What is the primary cause of ocean acidification?
-
Deforestation
-
Volcanic Eruptions
-
Burning of Fossil Fuels
-
Natural Disasters
C
Correct answer
Explanation
The burning of fossil fuels releases carbon dioxide into the atmosphere, which is absorbed by the ocean, leading to ocean acidification.

-
Deforestation
-
Soil erosion
-
Water pollution
-
Air pollution
A
Correct answer
Explanation
Deforestation is the main environmental challenge facing the Deccan Plateau, with large areas of forest being cleared for agriculture and development.
Which of the following is a major cause of deforestation?
-
Natural disasters
-
Agricultural expansion
-
Urban development
-
Forest fires
B
Correct answer
Explanation

Which of the following is a major cause of soil erosion?
-
Deforestation
-
Agricultural practices
-
Urban development
-
Mining
B
Correct answer
Explanation
Agricultural practices, such as plowing and overgrazing, can lead to soil erosion.

How do forests contribute to air quality?
-
By absorbing carbon dioxide and releasing oxygen
-
By filtering pollutants from the air
-
By providing habitat for wildlife
-
By regulating the climate
Correct answer
Explanation
Forests play a vital role in air quality by absorbing carbon dioxide and releasing oxygen, filtering pollutants from the air, providing habitat for wildlife, and regulating the climate.
How do forests help to reduce air pollution?
-
By absorbing pollutants
-
By releasing oxygen
-
By providing shade
-
By regulating the climate
Correct answer
Explanation
Forests help to reduce air pollution by absorbing pollutants, releasing oxygen, providing shade, and regulating the climate. These processes help to keep the air clean and healthy.
How do forests help to improve human health?
-
By providing clean air
-
By providing clean water
-
By providing food and shelter
-
By providing recreation opportunities
Correct answer
Explanation
Forests help to improve human health by providing clean air, clean water, food and shelter, and recreation opportunities. These benefits can help to reduce stress, improve mental health, and boost the immune system.
How do forests help to reduce the risk of flooding?
-
By absorbing rainwater
-
By releasing water vapor
-
By providing shade
-
By regulating the climate
Correct answer
Explanation
Forests help to reduce the risk of flooding by absorbing rainwater, releasing water vapor, providing shade, and regulating the climate. These processes help to keep the soil moist and prevent it from becoming saturated, which can lead to flooding.
Which of the following is NOT a consequence of deforestation?
-
Loss of Biodiversity
-
Soil Erosion
-
Increased Carbon Sequestration
-
Climate Change
C
Correct answer
Explanation
