A glacial lake is a lake with origins in a melted glacier. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks.

Is a glacial lake a result of deposition or erosion?
A glacial lake is typically a result of both erosion and deposition. Glacial erosion carves out depressions in the landscape, creating basins where water accumulates. Meanwhile, glacial deposition can form moraines or other features that dam up water and contribute to the formation of a glacial lake.
How does erosion or deposition play a part in forming lakes?
An example: lake basins can be formed from glacial erosion which can scrape off terrain, and lower the bedrock elevation from their sheer weight. When the glaciers recede, the basins are filled with meltwater, forming lakes. In a similar fashion, the deposition of sediments that form large landforms called moraines, can serve as dams creating lakes.
Can erosion and deposition occur or happen in still water such as a lake?
Yes, erosion can still occur in a lake through processes like weathering of the lake shoreline or sediment movement by underwater currents. Deposition can also occur in still water when sediments settle on the lakebed due to gravity or when carried by inflowing streams.
Is a delta made of erosion or deposition?
A delta is primarily formed through deposition. It consists of sediment that is carried by a river and deposited at its mouth where the river meets a body of water, such as an ocean or a lake. Erosion may play a role in shaping the delta, but the main process responsible for creating a delta is deposition.
Are deltas created by erosion or deposition?
Deltas are created by deposition. They form when sediment carried by a river is deposited as the river slows down and meets standing water, such as an ocean or lake. Erosion plays a role in shaping the delta, but the primary process involved in delta formation is deposition.

Which feature is not the result of a glacier carving out rock as it movess?
A feature that is not the result of a glacier carving out rock is a delta. Deltas are formed by the deposition of sediment carried by a river as it flows into a larger body of water, such as an ocean or lake, rather than through the erosive action of a glacier. In contrast, features like U-shaped valleys and glacial striations are directly caused by glacial movement and erosion.

Do underground caverns turn into lakes?
Under ground Caverns are Caused When a New Lake is being Formed, That keeps a Cave under the lake that soon Collapse Because the wieght of the lake/Water, Causes Erosion That Then Is Deposition because the Lake water fills up The under ground Cave.

Is large lake and large basin eroded by plucking and abrasion erosion or deposition?
Large lakes and basins are typically formed through processes of erosion, specifically plucking and abrasion, which are characteristic of glacial activity. Glaciers erode the landscape by removing material from the bedrock through these processes, creating depressions that can evolve into lakes. While sediment can be deposited in these basins over time, the initial formation of large lakes and basins is primarily due to erosion rather than deposition.
Are ox-bow lake formed by erosion or deposition?
Ox-bow lakes are primarily formed by erosion and deposition processes. As a river meanders, erosion occurs on the outer bends, while sediment is deposited on the inner bends. Over time, these processes can cause the river to cut off a meander, creating a crescent-shaped ox-bow lake. Thus, both erosion and deposition play critical roles in the formation of ox-bow lakes.
Are deltas created by erosion or deposition?
Deltas are created by deposition. They form when sediment carried by a river is deposited as the river slows down and meets standing water, such as an ocean or lake. Erosion plays a role in shaping the delta, but the primary process involved in delta formation is deposition.
