When compared to underground mining, why does surface mining have a larger impact on land ecosystems?

Answer 1

Surface mining has a larger impact on land ecosystems when compared to underground mining because it involves the removal of the topsoil and vegetation, which can lead to soil erosion, loss of biodiversity, and habitat destruction. Surface mining also generates large amounts of waste rock and tailings, which can contaminate nearby water sources and soil. Additionally, the use of heavy machinery and explosives in surface mining can cause noise pollution and air pollution, which can have negative impacts on wildlife and human health. In contrast, underground mining typically has a smaller footprint on the surface and can be less disruptive to ecosystems, although it can still have environmental impacts such as subsidence and groundwater contamination.

Answer 2

What enviormental impacts are caused by both surface mining and underground mining? Select two correct answers.

A. Destruction from overburden
B. Release of underground gases
C. Destruction of Ecosystems
D. Local water contamination
E. Sinkhole formation after mining is complete

Answer 3

A and D are the correct answers. Both surface mining and underground mining can cause destruction from overburden and local water contamination.

Answer 4

Which statement is true about the potential environmental impact on local water by both surface and underground mining?

A. Both types of mining can cause acid and heavy metals to get into local water.
B. Both types of mining cause high risk of sediment runoff
C. Both types of mining lead to overburden clogging small local waterways
D. Both types of mining can lead to a lowered water table

Answer 5

A is the correct answer. Both types of mining can cause acid and heavy metals to get into local water sources, leading to environmental damage and potential health risks.
