What is the primary environmental impact of stone quarrying?

  1. Air pollution

  2. Water pollution

  3. Land degradation

  4. Noise pollution


Correct Option: C
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.

Which of the following is a common air pollutant associated with stone quarrying?

  1. Carbon monoxide

  2. Sulfur dioxide

  3. Nitrogen oxides

  4. Particulate matter


Correct Option: D
Explanation:

Stone quarrying activities, such as blasting and crushing, can generate large amounts of particulate matter, which is a major air pollutant. These particles can be harmful to human health, particularly when inhaled.

How does stone quarrying contribute to water pollution?

  1. Acid mine drainage

  2. Sedimentation

  3. Eutrophication

  4. Thermal pollution


Correct Option: B
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.

What is the primary noise pollutant associated with stone quarrying?

  1. Blasting

  2. Crushing

  3. Hauling

  4. Drilling


Correct Option: A
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.

Which of the following is a potential ecological impact of stone quarrying?

  1. Habitat loss

  2. Fragmentation

  3. Edge effects

  4. Invasive species introduction


Correct Option: A
Explanation:

Stone quarrying can result in the loss of natural habitats, including forests, grasslands, and wetlands. This can have a negative impact on local wildlife, as it reduces the availability of food, shelter, and breeding grounds.

How does stone quarrying contribute to the release of greenhouse gases?

  1. Blasting

  2. Crushing

  3. Hauling

  4. Drilling


Correct Option: C
Explanation:

The transportation of stone from quarries to processing facilities or construction sites involves the use of heavy machinery and vehicles, which can emit greenhouse gases such as carbon dioxide and nitrogen oxides. These gases contribute to climate change and global warming.

Which of the following is a potential social impact of stone quarrying?

  1. Displacement of local communities

  2. Loss of cultural heritage

  3. Health problems

  4. Economic decline


Correct Option: A
Explanation:

Stone quarrying can sometimes lead to the displacement of local communities, particularly if the quarry is located in a rural area. This can disrupt traditional livelihoods and social networks, and can have a negative impact on the quality of life for those affected.

What is the primary method used to control air pollution from stone quarrying?

  1. Wet suppression

  2. Dry suppression

  3. Electrostatic precipitators

  4. Fabric filters


Correct Option: A
Explanation:

Wet suppression is a common method used to control air pollution from stone quarrying. This involves spraying water or a chemical suppressant onto the quarry site to reduce the generation of dust and particulate matter.

How can water pollution from stone quarrying be minimized?

  1. Constructing settling ponds

  2. Implementing erosion control measures

  3. Treating wastewater before discharge

  4. All of the above


Correct Option: D
Explanation:

To minimize water pollution from stone quarrying, a combination of measures can be employed, including the construction of settling ponds to trap sediment, the implementation of erosion control measures to prevent soil runoff, and the treatment of wastewater before it is discharged into the environment.

What is the primary method used to reduce noise pollution from stone quarrying?

  1. Blasting mats

  2. Noise barriers

  3. Mufflers

  4. Enclosed blasting


Correct Option: A
Explanation:

Blasting mats are commonly used to reduce noise pollution from stone quarrying. These mats are placed over the blast site to absorb and dampen the sound waves generated by the explosion.

How can the ecological impacts of stone quarrying be mitigated?

  1. Reclamation and restoration of quarry sites

  2. Establishment of buffer zones

  3. Wildlife corridors

  4. All of the above


Correct Option: D
Explanation:

To mitigate the ecological impacts of stone quarrying, a combination of measures can be employed, including the reclamation and restoration of quarry sites, the establishment of buffer zones around quarries to protect sensitive habitats, and the creation of wildlife corridors to allow animals to move freely between fragmented habitats.

What is the primary social impact of stone quarrying that can be addressed through community engagement?

  1. Displacement of local communities

  2. Loss of cultural heritage

  3. Health problems

  4. Economic decline


Correct Option: A
Explanation:

The displacement of local communities is a primary social impact of stone quarrying that can be addressed through community engagement. By involving local communities in the planning and decision-making process, their concerns can be heard and addressed, and measures can be taken to minimize the negative impacts of quarrying on their livelihoods and quality of life.

Which of the following is a potential economic impact of stone quarrying?

  1. Job creation

  2. Increased tax revenue

  3. Improved infrastructure

  4. All of the above


Correct Option: D
Explanation:

Stone quarrying can have several potential economic impacts, including job creation, increased tax revenue for local governments, and improved infrastructure development in the surrounding area. These benefits can contribute to the overall economic growth and prosperity of the region.

What is the primary regulatory framework in India that governs the environmental impact of stone quarrying?

  1. The Mines and Minerals (Development and Regulation) Act, 1957

  2. The Environment (Protection) Act, 1986

  3. The Water (Prevention and Control of Pollution) Act, 1974

  4. The Air (Prevention and Control of Pollution) Act, 1981


Correct Option: A
Explanation:

The Mines and Minerals (Development and Regulation) Act, 1957 is the primary regulatory framework in India that governs the environmental impact of stone quarrying. This act provides for the regulation of mining and quarrying activities, including the grant of mining leases, the protection of the environment, and the safety of workers.
