soil erosion caused by construction and mining

What Is Soil Erosion? Definition, Causes, Effects

Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion. The effects of soil erosion are not just land degradation. It has led to a drastic increase in pollution and sedimentation in rivers that clogs the water bodies resulting in a decline in the population of aquatic organisms.

Study Minerals and Mining Flashcards Quizlet

Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.
