I only know that there are distinctly shaped valleys formed by varying types of erosion. Streams and rivers have a lot of gravitational potential energy upstream (as they often have sources in mountains or hills) and so tend to erode vertically in their upper course creating steeply sided v-shaped valleys with very little/no floodplain. As you follow the river downstream the erosional direction changes to become more latteral (horizontal) resulting in valleys with less steep sides and wider floodplains. Glacial movement, however, leads to the creation of even steeper sided u-shaped valleys which can be very wide at the bottom. These are not to be confused with gorges which are created as waterfalls on rivers retreat upstream with consequetive episodes of undercutting and collapse, which tend to be even steeper sided and normally are rather narrow, however this depends on the size and type of the original waterfall as well as the discharge of the river. Wind does not tend to form valleys but rather sculpts those which already exist, by the process of differential erosion, through which different rock types erode at different rates leading to the formation of the beautifully shaped rocks we find sticking out of the desert as well as yardangs and zeugen.
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.
Glaciers have significantly shaped Ohio's landscape, resulting in features like the Great Lakes, which were formed by glacial erosion and deposition. The state also boasts numerous glacial till plains, which are fertile areas created from the sediments left behind as glaciers retreated. Additionally, the formation of moraines, or ridges of debris, can be observed in various parts of Ohio, marking the former positions of glaciers.
Erosion is the process by which soil and rocks are broken down and transported by wind, water, or ice. Common types of erosion include water erosion (caused by rainfall and runoff), wind erosion (caused by wind carrying away soil particles), and glacier erosion (caused by glaciers picking up and moving rocks and debris).
Abrasion is considered one of the strongest types of erosion, where rocks and sediments are carried by water or wind and scrape against surfaces, wearing them down over time. This process can result in the formation of features such as valleys, canyons, and caves.
Erosion by wind and water. Earthquakes caused by tectonic plate movement. Volcanic eruptions that release magma and gases. Weathering from exposure to elements like rain, heat, and cold. Landslides and rockfalls. Glacial movement carving out landscapes. Coral reef formation and erosion. Subsidence due to groundwater extraction or natural processes. Tsunamis caused by underwater seismic activity. Sinkholes forming due to erosion of soluble rocks such as limestone.
U-shaped valleys, cirques, and fjords are landforms caused by glacial erosion. Glaciers carve these features into the landscape as they move and shape the land over time.
The 3 main types of glacial erosion are plucking, abrasion and freeze thaw.

Glacial erosion is the process by which glaciers cut, scrape, and transport material like rock and sediment as they move, shaping the landscape through actions like plucking and abrasion. Water erosion, on the other hand, is the process by which water wears away rock and soil through processes like runoff, streams, and waves, leading to the formation of features like valleys and river channels. Ultimately, glacial erosion tends to be more powerful and can carve out larger and deeper landforms compared to water erosion.
Yes, glacial valleys are often U-shaped due to the erosion caused by glaciers. As glaciers advance, they scoop out and widen valleys, resulting in a distinct U-shaped profile. This glacial erosion process leaves behind characteristic features like steep sides and flat bottoms.
Three transporting agents of erosion are water, wind, and ice. Water erosion is caused by rivers, streams, and rainfall, while wind erosion occurs in arid and windy environments. Ice erosion, known as glacial erosion, is caused by the movement of glaciers.
Glacial erosion is caused by moving masses of ice. As glaciers flow over the land, they pick up rocks and debris, scraping and carving the land beneath them. This process shapes the landscape through processes such as plucking and abrasion.
The type of erosion that is caused by moving masses of ice is called glacial erosion.
No, eskers are not caused by glacial erosion. Eskers are long, winding ridges of sand and gravel that are formed by meltwater streams flowing in tunnels within or under glaciers. Glacial erosion refers to the process by which glaciers carve and shape the land through the movement of ice and debris.
Glacial striations are a result of erosion. They are scratches and grooves on bedrock caused by rocks and debris being dragged along by moving glaciers.
The formation of valleys can be caused by different types of erosion, primarily by the flowing of water (fluvial erosion) or by glaciers (glacial erosion). Fluvial erosion occurs when water flows through a valley, gradually wearing down the rock and soil. Glacial erosion happens when moving glaciers cut and shape the land as they advance and retreat.
Yes, striations are a glacial feature caused by the erosion of bedrock as a glacier moves over it. These scratches or grooves are formed by the rocks and debris embedded in the ice scraping against the underlying rock surface.
