Is striations a glacial feature caused by erosion?
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.
Is moraines a glacial feature caused by erosion?
Moraines are not caused by erosion, but rather by the deposition of sediment and rocks carried and deposited by a glacier as it moves and melts. Erosion occurs as the glacier carries material away from its original location.
Which is a glacier feature caused by erosion?
In cross-section: A 'U' shaped valley is formed from glacial erosion. A 'V' shaped valley is formed by river erosion.
What cause differential weathering?
Differential weathering is caused by variations in the resistance of rocks to weathering processes such as erosion, chemical weathering, and physical weathering. Rocks with varying mineral composition, hardness, and structure will weather at different rates, leading to the uneven erosion of landscapes. Additionally, factors such as climate, topography, and human activities can influence the rate and pattern of differential weathering.
What are two factors that cause differential weathering?
Differential weathering is caused by variations in rock composition (such as differences in mineral hardness or solubility) and differences in rock structure (such as joints, fractures, or bedding planes). These variations can lead to differential erosion rates, resulting in the formation of unique landforms.

Can Unconformities be caused by erosion?
Unconformities are either a feature of deposition or igneous extrusions; and are not as a result of erosion, yet the material making one up may be a product of erosion.
What is meant by the term differential erosion can you give an example of differential erosion found in the flagstaff area?
Niagara falls was formed by differental erosion

Is terminal moraines a glacial feature caused by erosion?
Terminal moraines are not formed due to erosion but rather deposition. They are ridges of glacial till that mark the farthest advance of a glacier and are deposited as the glacier retreats. Erosion by the glacier does contribute to the material found in terminal moraines, but the feature itself is primarily a result of deposition.
Are sea stacks caused erosion or deposition?
Sea stacks are primarily formed by erosion. They are created when the relentless force of waves erodes the weaker parts of cliffs and headlands, leaving behind isolated rock formations. As the land erodes, the sea stack is separated from the mainland, becoming a distinctive coastal feature.
What are the three main types of erosion?
The 3 main types of glacial erosion are plucking, abrasion and freeze thaw.
How is erosion caused by rivers different than erosion caused by glaciers?
the cause by the change of the earth
What are the 4 major types of erosion?
The four major types of erosion are water erosion (caused by runoff and water flow), wind erosion (caused by wind moving particles), ice erosion (caused by glaciers and ice melt), and gravity erosion (caused by gravity moving rocks and soil downhill).
