Question

1. which of the following best describes the process known as

\mountaintop removal\?

the use of trees planted at high elevations to eliminate carbon dioxide from the
atmosphere

the use of heavy equipment to move overburden downhill during the mining of
coal

the placement of hazardous - waste disposal sites at high elevations in
mountainous regions

the shearing away of undersea mountain peaks to improve shipping lanes

Explanation:

Mountaintop removal is a coal mining technique where heavy equipment is used to remove the top of a mountain (overburden) to access coal seams, and the overburden is often moved downhill. The first option is about carbon sequestration via trees, the third is about hazardous waste disposal, and the fourth is about undersea mountains for shipping—none match mountaintop removal's definition.

Answer:

B. The use of heavy equipment to move overburden downhill during the mining of coal
