How does gravity move sediments?

Answer 1

Gravity is the force behind precipitation in the water cycle. Rain, snow and other forms of falling water are carried to earth by gravity. There, the liquid water can wash materials away. Snow can accumulate and melt and do the same thing. Snow can also accumulate, freeze, and then become moving ice (a glacier). We know glaciers can move massive amounts of rock and other materials, and can shear off or grind materials because of their weight and/or the force of the moving ice mass.

We also know that gravity directly acts to "pull down" weakened geologic structures, like cliffs or even mountain sides. Loose rock or earth is dragged down from higher points all the time, and it might be one or two chunks of material, or a landslide. Even the great spires in places like Monument Valley will eventually succumb to gravity's pull.

Answer 2

Water's attempt to get to sea level via gravity will strongly affect the force of weathering. A great example is the Grand Canyon. There, the uplifted Colorado Plateau was deeply incised by the downward rushing waters of the Colorado River and its tributaries.

Answer 3

Gravity affects the deposition of sediments because it pulls the particles from one location to another. As the water slows down, the sediment will drop.

Answer 4

By moving it
