  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation contributes to desertification in Rajasthan by reducing the amount of vegetation that can hold the soil in place, increasing the amount of water that evaporates from the soil, and making the soil more susceptible to erosion.

Multiple choice

How does overgrazing contribute to desertification in Rajasthan?

  1. It removes the vegetation that helps to hold the soil in place.

  2. It compacts the soil, making it less able to absorb water.

  3. It increases the amount of dust that is blown away by the wind.

  4. All of the above

Multiple choice

What is the primary cause of desertification in India?

  1. Deforestation

  2. Overgrazing

  3. Climate Change

  4. Industrial Pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation is the primary cause of desertification in India, as it leads to soil erosion and loss of vegetation, making the land more susceptible to desertification.

Multiple choice

What is the primary cause of habitat destruction resulting from mining and quarrying?

  1. Removal of vegetation

  2. Soil erosion

  3. Water pollution

  4. Air pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mining and quarrying activities often involve the removal of vegetation to access mineral deposits, leading to habitat destruction.

Multiple choice
