  1. Increased water retention

  2. Reduced soil erosion

  3. Enhanced water quality

  4. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation leads to decreased water retention, increased soil erosion, and deteriorated water quality.

Multiple choice

What is the primary cause of wetland loss and degradation due to mining?

  1. Deforestation

  2. Urbanization

  3. Agricultural Expansion

  4. Mining Activities
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mining operations, including extraction, processing, and waste disposal, directly impact wetlands by altering their hydrology, destroying vegetation, and releasing contaminants.

Multiple choice

What is the primary cause of dust storms?

  1. High winds

  2. Droughts

Multiple choice

What is the primary cause of waterlogging in agricultural areas?

  1. Excessive rainfall

  2. Poor drainage

  3. Over-irrigation

  4. Deforestation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Poor drainage is the primary cause of waterlogging in agricultural areas, as it prevents excess water from draining away.

Multiple choice

Which of the following is NOT a potential environmental cost of FDI in India?

  1. Pollution

  2. Deforestation

  3. Soil erosion

  4. Increased energy consumption
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
