-
Air pollution
-
Water pollution
-
E-waste
-
Noise pollution
C
Correct answer
Explanation

-
Air pollution
-
Water pollution
-
Soil contamination
-
Noise pollution

What is the primary environmental impact of diorite quarrying?
-
Air pollution
-
Water pollution
-
Land degradation
-
Noise pollution
C
Correct answer
Explanation
Diorite 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 increased risk of erosion and landslides.
What are some of the potential environmental impacts of diorite quarrying on nearby ecosystems?
-
Air pollution
-
Water pollution
-
Land degradation
-
All of the above
D
Correct answer
Explanation
Diorite quarrying can pose a number of environmental risks to nearby ecosystems. Air pollution from dust and chemicals can harm plants and animals. Water pollution from runoff and leaching can contaminate water sources and harm aquatic life. Land degradation from quarrying and waste disposal can destroy habitat and make it difficult for plants and animals to survive.
What are some of the potential environmental impacts of diorite quarrying on the global environment?
-
Climate change
-
Air pollution
-
Water pollution
-
All of the above
D
Correct answer
Explanation
Diorite quarrying can pose a number of environmental risks to the global environment. Quarrying can contribute to climate change by releasing greenhouse gases. It can also lead to air pollution and water pollution. Additionally, quarrying can destroy habitat and contribute to the loss of biodiversity.
What are some of the potential economic impacts of diorite quarrying on the global environment?
-
Loss of revenue from tourism
-
Increased healthcare costs
-
Loss of agricultural productivity
-
All of the above
D
Correct answer
Explanation
Diorite quarrying can pose a number of economic risks to the global environment. Quarrying can lead to a loss of revenue from tourism, as people may be less likely to visit areas that are affected by quarrying. It can also lead to increased healthcare costs, as people who are exposed to harmful dust and chemicals from quarrying may experience health problems. Additionally, quarrying can lead to a loss of agricultural productivity, as land that is used for quarrying can no longer be used for farming.
What are some of the potential environmental impacts of diorite quarrying on the local environment?
-
Air pollution
-
Water pollution
-
Land degradation
-
All of the above
D
Correct answer
Explanation
Diorite quarrying can pose a number of environmental risks to the local environment. Quarrying can generate dust and chemicals that can pollute the air. It can also lead to water pollution from runoff and leaching. Additionally, quarrying can destroy habitat and contribute to land degradation.
