When does an arête form?
Arêtes can form in two ways. They can form when two glaciers erode parallel U-shaped valleys, or they can form when two glacial cirques erode headwards toward one another, although frequently this results in a saddle-shaped pass, called a col.
How are glacier sediments deposited directly by glacial ice compared with those deposited by glacial meltwater?
fortniye
What shape valley does a glacier leave?
Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
What kind of land forms can be formed when a glaciers begins melting back and deposits the sediment it has been carrying with?
When a glacier melts, it deposits sediment in various landforms known as glacial landforms. These include moraines, which are accumulations of debris at the glacier's edge, drumlins, which are elongated hills shaped by the glacier's movement, and outwash plains, formed by meltwater transporting and depositing sediments beyond the glacier's terminus. These features reflect the dynamic processes of glacial erosion and deposition, shaping the landscape as the ice retreats.
Explain the difference between erosion and deposition?
Glacial erosion is the process by which a glacial flows over the land, picking up rocks. Glacial deposition is the process by which a glacier gathers a huge amount of rock and soil as it Erodes the land in the path
What are two typyes of glacial deposits?
Two types of glacial deposits are moraines, which are formations of mixed sediment pushed by and deposited from a glacier, and drumlins, which are elongated hills made of glacial till that form parallel to the direction of ice flow.
What were hills in southern Illinois created by?
"Moraine" hills,...caused by glacial deposits while receding.
What part of speech is the word erosion?

The glacial features that occur in swarms of long and smooth canoe shaped hills are?

What form by glacial erosion?
Eskers
Can glacial ice form during the duration of a single winter season in most glacial areas?
No
What glacial features results from deposition?
Moraines, drumlins, eskers, and outwash plains are glacial features that result from deposition. Moraines are ridges of till deposited along the edges of a glacier, drumlins are elongated hills of glacial till, eskers are long, winding ridges of sand and gravel, and outwash plains are flat areas of sand and gravel deposited by meltwater streams flowing away from the glacier.
What percentage of earths water is in the form of glacial ice?
Approximately 69%
How did plains form millions of years ago?
there are three reasons first the wind the rain the magma and the erosions
What are the types of features that form from glacial erosion?
Glacial Erosion formed Yosemite Valley and the Sierra Nevada
What part of South Dakota was covered in glaciers?
During the last Ice Age, glaciers covered the eastern part of South Dakota, particularly the region known as the Glacial Lake Dakota area. This glaciated region features rolling hills and plains shaped by glacial activity. The western part of South Dakota, including the Black Hills, remained largely unaffected by glacial coverage.
