Answer:
Introduction
The footprints that astronauts left on the Moon will be there forever. Why? This is because the Moon has no atmosphere and, as a result, has no weathering. Weathering is one of the forces on Earth that destroy rocks and landforms. Without weathering, geologic features would build up but would be less likely to break down.
What is Weathering?
Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces.
Once these sediments are separated from the rocks, erosion is the process that moves the sediments. Erosion is the next chapter’s topic. The four forces of erosion are water, wind, glaciers, and gravity.
Water is responsible for most erosion. Water can move most sizes of sediments, depending on the strength of the force.
Wind moves sand-sized and smaller pieces of rock through the air.
Glaciers move all sizes of sediments, from extremely large boulders to the tiniest fragments.
Gravity moves broken pieces of rock, large or small, downslope.
