Answer;
-All the above
- erosion
- an open pit
- sedimentation
Explanation;
-Surface mining removes ore deposits that are close to the surface, and subsurface mining removes minerals that are deep underground. While mineral use is very important to us, there are also many environmental impacts, such as erosion, air and water pollution, land destruction and harm to mine workers.
-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.Besides creating environmental damage, the contamination resulting from leakage of chemicals also affects the health of the local population.
