Answer
Brief Explanations:
Surface mining can cause significant land - use change and soil erosion. Placer mining involves the separation of valuable minerals from sediments in water bodies and can cause sedimentation and habitat disruption. Subsurface mining generally has less surface - level environmental impact as it disturbs less of the surface area compared to surface and placer mining.
