An esker is a glacial landform that is created by deposition. Eskers are long, winding ridges of sand and gravel left behind by streams within or under glaciers. They form as the glacier melts and recedes, leaving behind sediment deposited by the flowing water.

How does glacial erosion and glacial deposition affect the face of the earth?
Glacial erosion shapes the land by scraping and polishing the surface, creating features like U-shaped valleys and cirques. Glacial deposition occurs when the ice melts and deposits the sediments it carried, forming landforms like moraines and drumlins. Together, these processes have significantly shaped the Earth's landscape over millions of years.
What is the difference between glacial erosion and glacial deposition?
Glacial erosion refers to the process where glaciers wear away the land by scraping and gouging the surface, while glacial deposition is the process where glaciers deposit materials like rocks, sediments, and other debris that they pick up as they move. Erosion creates features like U-shaped valleys and cirques, while deposition creates features like moraines and drumlins.
What type of glaciers are there and how do they erode the land?
glacial deposition and glacial erosion
How are glacial plains formed?
Glacial plains are formed by the deposition of sediments carried by glaciers as they advance and retreat. When glaciers move, they pick up rocks, soil, and other materials, which are then deposited when the glacier melts. Over time, these deposited materials accumulate to create flat, wide expanses of land known as glacial plains.
Is glacial lake caused by erosion or deposition?
Glacial lakes are primarily caused by deposition. As glaciers move, they erode the land beneath them and create depressions where meltwater collects, forming glacial lakes. The deposition of sediment carried by the glacier contributes to the formation and shape of the lake.
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
Is a drumlin caused by erosion?
A drumlin is a land-form from glacial deposition, which was once eroded. It is formed both by erosion and deposition. A drumlin is formed when moraine deposited by a retreating glacier is subsequently reshaped by the returning glacier the following year or after the glacial interval with caused the glacier to retreat in the first place.

How are drumlins form?
A Drumlin is a sub-glacial land form. It is a result of catastrophic flooding due to the release of melt water accumulating beneath ice sheets of regional uplift of tectonic movements.
What are two land-forms form by river deposition?
River deposition creates landforms such as alluvial and deltas.
What type of glaciers are there and how do they erode the land?
glacial deposition and glacial erosion
How are glacial plains formed?
Glacial plains are formed by the deposition of sediments carried by glaciers as they advance and retreat. When glaciers move, they pick up rocks, soil, and other materials, which are then deposited when the glacier melts. Over time, these deposited materials accumulate to create flat, wide expanses of land known as glacial plains.
A stream Valley Land form is the most common result of what?
A stream valley is usually 'V' shaped, formed by erosion from a stream. A glacial valley is usually 'U' shaped, formed by the action of a glacier.
How does deposition affect land form?
It slowly degrades shores and walls on the sea or rivers.
How do landform evolve?
There are many different ways that a land form evolve. These land forms can evolve by erosion or deposition for example.
Is glacial lake caused by erosion or deposition?
Glacial lakes are primarily caused by deposition. As glaciers move, they erode the land beneath them and create depressions where meltwater collects, forming glacial lakes. The deposition of sediment carried by the glacier contributes to the formation and shape of the lake.
