Learn about and revise glacial landforms and processes, including weathering, erosion, transportation and deposition, with GCSE Bitesize Geography (AQA).The mass movement process, also sometimes called mass wasting, occurs when soil and rock move down a slope under the force of gravity. The movement of the material is called creeping, sliding, flowing, toppling, and falling. Each of these depends on the speed and composition of the material moving. This process is both erosional and depositional.Glacial rock dust is a rock powder that is also used to feed and fertilize the soil.

Let’s take a closer look at what their differences are. Glacial Rock Dust. as the name says, is made from rocks deposited by glacial action. When glaciers move across the landscape, they pick up rocks and carry them for tens or even hundreds of miles. The turquoise lakes are fed by rivers where large, active glaciers are pushing through rocky valleys upstream. The glaciers function like bulldozers, grinding away and pulverizing rocks along valley floors and walls. The process produces a fine-grained powder of silt and clay— glacial flour —that is picked up by meltwater streams.It is a plain formed of glacial sediments deposited by meltwater outwash at the limit of a glacier.
