What are glaciers describe an erosional and depositional features caused by glaciers?
Glaciers cause erosion by plucking and abrasion. Valley glaciers form several unique features through erosion, including cirques, arêtes, and horns. Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers.
What are the erosional features created by continental glaciation?
Continental Glacial Erosion Features Glacial deposits have created distinctive topographic features on the landscapes in these regions — such as drumlins, eskers, and moraines (Figure 17.16).
Does Greenland have continental glaciers?
Continental glaciers are continuous masses of ice that are much larger than alpine glaciers. … Big continental glaciers are called ice sheets. Greenland and Antarctica are almost entirely covered with ice sheets that are up to 3500 m (11 500 ft) thick.
What kind of glaciers are in Greenland?
Greenland and Antarctica The largest glaciers are continental ice sheets or icecaps, enormous masses (greater than 50,000 square kilometers [12 million acres]) of ice found only in Antarctica and Greenland. These sheets contain vast quantities of fresh water.
What is an erosional feature of a glacier?
As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
What are some erosional landforms formed by glacial ice?
Fjords, glaciated valleys, and horns are all erosional types of landforms, created when a glacier cuts away at the landscape. Other types of glacial landforms are created by the features and sediments left behind after a glacier retreats.
What are the three types of continental glaciers?
There are primarily three types of continental glaciers, namely ice caps, ice sheets, and outlets.
Which is the depositional feature of a glacier?
Moraine: Moraine is the depositional feature of a glacier.
What is the depositional feature of glacier called?
Option B: Moraines comprise of sediments, rocks, debris, dirt and more which are transmitted by the glaciers when moves down the mountains slowly. Hence, it is the depositional feature of glacier.
What are glacial depositional features?
U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins.
