Multiple choice

What is the primary environmental impact of stone quarrying?

  1. Air pollution

  2. Water pollution

  3. Land degradation

  4. Noise pollution
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Stone quarrying involves the removal of large amounts of rock and soil, which can lead to significant land degradation. This can result in the loss of vegetation, soil erosion, and the formation of unsightly scars on the landscape.

Multiple choice

How does stone quarrying contribute to water pollution?

  1. Acid mine drainage

  2. Sedimentation

  3. Eutrophication

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

Stone quarrying can lead to increased sedimentation in nearby water bodies. This occurs when soil and rock particles from the quarry are washed away by rainwater or runoff, resulting in the accumulation of sediment in rivers, lakes, and streams.

Multiple choice

What is the primary noise pollutant associated with stone quarrying?

  1. Blasting

  2. Crushing

  3. Hauling

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

Blasting is a common method used to extract stone from quarries. This process involves the use of explosives, which can generate significant noise pollution. The noise from blasting can travel long distances and can be disruptive to nearby communities.

  1. Deforestation

  2. Overgrazing

  3. Industrial waste

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

Deforestation, overgrazing, and industrial waste are all major causes of soil pollution in India, leading to the degradation of soil quality and its ability to support agriculture.
