questions correctly for a thumbs up
Match each statement to the surficial mining technique it describes. Strip mining Miners partially process coal on-site and store coal sludge in ponds. Miners store overburden nearby with fewer environmental impacts. Once the miners remove coal seams, they have difficulty in restoring the original topography and vegetation. Answer Bank Miners store overburden in adjacent valleys, burying streams and filling in the valley. Miners access surface coal seams on rugged land surfaces. Mountaintop removal Once the miners remove coal seams, they return overburden to the original topography and plant vegetation. Miners rely heavily on explosives to blast away rock lying above coal seams. Miners systematically remove overburden. Miners access surface coal seams in fairly level land surfaces.

What types of energy sources can be used to directly power vehicles? renewable biomass moving water fossil fuel oil compressed natural gas geothermal heat
Please answer all Match each statement to the surficial mining technique it describes. Strip mining Miners partially process coal on-site
