What are 3 features formed by glacial deposition?
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.
What are the 6 agents of erosion?
What are the 6 agents of erosion? Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows.
Which is a form of glacial deposition?
Debris in the glacial environment may be deposited directly by the ice (till) or, after reworking, by meltwater streams (outwash). The resulting deposits are termed glacial drift.
What is the meaning of deposition in geography?
Deposition is a geological process where rocks, soil, and silt are naturally deposited so that new land masses are formed or modified. Learn the definition of deposition and understand how it works with erosion, volcanic eruption, water, ice, wind and gravity.
What are some examples of glacial erosion?
Glacial lakes are examples of ice erosion. They occur when a glacier carves its way into a place and then melts over time, filling up the space that it carved out with water. One such glacial lake is called Lake Louise and is located in Alberta, Canada.
What are 2 basic processes of glacial erosion?
Erosion processes. The primary processes of glacial erosion are plucking, abrasion, and physical and chemical erosion by subglacial water.
What are the two main types of glaciers?
There are two main types of glaciers: continental glaciers and alpine glaciers. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers.
