Transcript of Glacial Deposition

10 facts about glacial deposition Till Glacial-till can form excellent soil for farmland. Material a glacier picks up or pushes as it moves forms moraines along the surface and sides of the glacier. As a glacier retreats-, the ice literally melts away from underneath the moraines.Glacial lake- is a lake with origins in a melted glacier.Moraine-an accumulation of earth and stones carried and finally deposited by a glacier. 10 Facts about Glacial Deposition Glacial Deposition Vocab Words Geology-the science that deals with the dynamics and physical history of the earth.
Etymology- the derivation of word origin, word source , derivation, origin. Questions 1.How does glacial deposition occur? 2.What is the difference between glacial erosion and glacial deposition? Glacial deposition- A persistent body of ice that flows and originates on land. How Glaciers affect the land Glaciers not only transport material as they move, but they also sculpt and carve away the land beneath them.

The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.

Glacial Landforms Fjords, glaciated valleys,and horns are all erosional types of landforms, created when a glacier cuts away at the landscape.

Till is material that is deposited as glaciers retreat, leaving behind mounds of gravel, small rocks, sand and mud. 1.Glacial deposition occurs when a glacier melts, and deposits the sediments it eroded from the land. 2. They are opposites. Erosion is the natural process of removing sediment while deposition is the process of adding sediments .So when a glacier picks up rocks and sediments as it builds up and grows,that's glacial erosion
