What is the primary environmental impact of gabbro quarrying?

  1. Air pollution

  2. Water pollution

  3. Land degradation

  4. Noise pollution


Correct Option: C
Explanation:

Gabbro 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 habitat for plants and animals, as well as an increase in erosion and sedimentation.

Which of the following is NOT a potential air pollutant released during gabbro quarrying?

  1. Dust

  2. Sulfur dioxide

  3. Nitrogen oxides

  4. Carbon monoxide


Correct Option: D
Explanation:

Carbon monoxide is not typically released during gabbro quarrying, as it is a product of incomplete combustion. The other options, however, are all potential air pollutants that can be released during quarrying operations.

How can gabbro quarrying impact water quality?

  1. By releasing sediment into water bodies

  2. By increasing the salinity of water

  3. By introducing heavy metals into water

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying can impact water quality in a number of ways. Sediment released from quarrying operations can clog waterways and smother aquatic life. Quarrying can also increase the salinity of water, making it harmful to plants and animals. Additionally, heavy metals released from quarrying can contaminate water sources and pose a health risk to humans and wildlife.

What is the primary noise pollutant associated with gabbro quarrying?

  1. Blasting

  2. Hauling

  3. Crushing

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying involves a number of activities that can generate noise pollution, including blasting, hauling, and crushing. Blasting is the most significant source of noise pollution, as it can produce sound levels that exceed 100 decibels. Hauling and crushing operations can also generate significant noise, particularly if they are conducted near residential areas.

Which of the following is NOT a potential impact of gabbro quarrying on biodiversity?

  1. Habitat loss

  2. Fragmentation of habitat

  3. Introduction of invasive species

  4. Increased genetic diversity


Correct Option: D
Explanation:

Gabbro quarrying is unlikely to increase genetic diversity, as it typically involves the removal of large amounts of rock and soil, which can destroy habitat and fragment populations. Habitat loss and fragmentation can lead to a decrease in genetic diversity, as populations become isolated and less able to exchange genes.

How can gabbro quarrying contribute to climate change?

  1. By releasing greenhouse gases

  2. By reducing the amount of vegetation

  3. By increasing the amount of impervious surfaces

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying can contribute to climate change in a number of ways. The quarrying process itself can release greenhouse gases, such as carbon dioxide and methane. Additionally, the removal of vegetation and the creation of impervious surfaces can both contribute to climate change by increasing the amount of heat absorbed by the Earth's surface.

What is the primary method used to control dust emissions from gabbro quarrying operations?

  1. Water sprays

  2. Chemical dust suppressants

  3. Windbreaks

  4. All of the above


Correct Option: D
Explanation:

A combination of methods is typically used to control dust emissions from gabbro quarrying operations. Water sprays can be used to suppress dust at the source, while chemical dust suppressants can be applied to roads and other surfaces to prevent dust from becoming airborne. Windbreaks can also be used to help reduce the amount of dust that is generated.

How can gabbro quarrying impact the visual landscape?

  1. By creating unsightly scars on the land

  2. By blocking views of natural features

  3. By increasing light pollution

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying can impact the visual landscape in a number of ways. The quarrying process itself can create unsightly scars on the land, while the presence of quarrying equipment and infrastructure can block views of natural features. Additionally, quarrying operations can generate light pollution, which can disrupt the natural night sky.

What is the primary method used to reclaim gabbro quarries after they are no longer in operation?

  1. Revegetation

  2. Reforestation

  3. Wetland restoration

  4. All of the above


Correct Option: D
Explanation:

A combination of methods is typically used to reclaim gabbro quarries after they are no longer in operation. Revegetation and reforestation can be used to restore vegetation to the site, while wetland restoration can be used to create new or restore existing wetlands. In some cases, a combination of these methods may be used to create a diverse and sustainable ecosystem.

What is the primary social impact of gabbro quarrying?

  1. Job creation

  2. Economic development

  3. Displacement of local communities

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying can have a number of social impacts, both positive and negative. On the positive side, quarrying can create jobs and contribute to economic development. However, quarrying can also displace local communities and disrupt traditional livelihoods. Additionally, quarrying can have a negative impact on the social fabric of communities, as it can lead to conflict and division.

Which of the following is NOT a potential health risk associated with gabbro quarrying?

  1. Respiratory problems

  2. Cardiovascular disease

  3. Cancer

  4. Heat stroke


Correct Option: D
Explanation:

Heat stroke is not typically associated with gabbro quarrying, as it is a condition that is caused by exposure to high temperatures. However, the other options are all potential health risks associated with gabbro quarrying. Respiratory problems can be caused by exposure to dust and other air pollutants, cardiovascular disease can be caused by exposure to noise and vibration, and cancer can be caused by exposure to heavy metals and other hazardous substances.

How can gabbro quarrying impact the cultural heritage of an area?

  1. By destroying archaeological sites

  2. By disrupting traditional cultural practices

  3. By altering the landscape

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying can impact the cultural heritage of an area in a number of ways. Quarrying can destroy archaeological sites and disrupt traditional cultural practices. Additionally, quarrying can alter the landscape, which can have a negative impact on the cultural identity of a community.

What is the primary legal framework in India that regulates gabbro quarrying?

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

  2. The Environment Protection Act, 1986

  3. The Forest Conservation Act, 1980

  4. All of the above


Correct Option: D
Explanation:

Gabbro quarrying in India is regulated by a number of laws, including the Mines and Minerals (Development and Regulation) Act, 1957, the Environment Protection Act, 1986, and the Forest Conservation Act, 1980. These laws set out the requirements for obtaining permits and licenses for quarrying operations, as well as the environmental and social safeguards that must be put in place.

What is the primary role of the Ministry of Environment, Forest and Climate Change (MoEFCC) in regulating gabbro quarrying?

  1. To grant environmental clearances for quarrying projects

  2. To enforce environmental regulations

  3. To promote sustainable quarrying practices

  4. All of the above


Correct Option: D
Explanation:

The MoEFCC plays a key role in regulating gabbro quarrying in India. The ministry is responsible for granting environmental clearances for quarrying projects, enforcing environmental regulations, and promoting sustainable quarrying practices. The MoEFCC also works with other government agencies to ensure that gabbro quarrying is conducted in a responsible and sustainable manner.
