After glaciation, a valley can become a U-shaped valley, which is wider and shallower compared to the original V-shaped valley. This transformation is due to the erosion caused by the movement of glaciers, which tend to widen and deepen valleys as they erode and transport material.

Which would be likely to occur in a region of continetal glaciation but not in a region of valley glaciaton?
The presence of large ice sheets covering extensive land areas would be likely in a region of continental glaciation. This type of glaciation is characterized by vast ice sheets that spread over entire continents, unlike valley glaciation which occurs in mountain valleys and is more localized in scope.
How does the shape of a stream valley compare to the shape of a glacial valley?
A stream valley typically has a V-shape, while a glacial valley has a U-shape. This difference in shape is due to the different erosional processes involved. Stream valleys are eroded mainly by flowing water, while glacial valleys are shaped by the movement of glaciers that scrape and pluck rock and sediment.
What causes a glacial valley to be U-shaped Write your answer as a short detailed paragraph.?
A glacial valley becomes U-shaped through the process of glacial erosion. As a glacier moves down a valley, it erodes the land beneath it through a combination of abrasion and plucking. Abrasion occurs when the glacier grinds and sculpts the valley walls and floor, while plucking involves the glacier picking up and removing rock fragments. Over time, these erosional processes create a deep and wide valley with steep, straight sides characteristic of a U-shape.
What is a lowland area between higher land such as mountains?
A lowland area between higher land is known as a valley. Valleys are typically created by geological processes like erosion and glaciation, and they often contain rivers or streams that flow through them. These areas are important for agriculture, settlement, and transportation due to their relatively flat terrain.
How does glaciation work?
Glaciation occurs when snow accumulates over time and compresses into ice. This ice then flows downhill under its weight, forming glaciers. Glaciers erode the land, carving out valleys and shaping the landscape through processes like plucking and abrasion.
What is the movement of a glacier?
As a glacier moves through a valley, it digs deep into the walls and floor . A once-narrow valley that had a V shape becomes wider. As a glacier moves through, the valley becomes U shape .
How is the origin of the great lakes and yosemite valley similar?

Which would be likely to occur in a region of continetal glaciation but not in a region of valley glaciaton?
The presence of large ice sheets covering extensive land areas would be likely in a region of continental glaciation. This type of glaciation is characterized by vast ice sheets that spread over entire continents, unlike valley glaciation which occurs in mountain valleys and is more localized in scope.
Why are glaciers formed in a U shape?
Glaciers form in a U shape due to the process of glaciation, where ice flows downhill under the influence of gravity. As the glacier moves, it erodes the valley walls and floor, widening and deepening the valley. The characteristic U shape results from this erosional process, contrasting with the V-shaped valleys formed by river erosion. Additionally, the weight of the ice concentrates erosion at the valley bottom, further enhancing the U-shaped profile.
Which would be likely to occur in a region of continental glaciation but not in a region of valley?
The presence of large moraines (deposits of glacial till), erratic rocks (boulders carried by glaciers), and drumlins (elongated hills formed by glacial action) would be more likely in a region of continental glaciation compared to a region of valley glaciation. The larger scale and extensive coverage of ice in continental glaciation are responsible for shaping the landscape in these ways.
Explain how glaciation weathering and erosion create and shape valleys and floodplains?
#cmt review
Which feature is currently found in the yosemite valley region as a result of glacation?
Yosemite Valley's creation can be credited to glaciation. When the glacier advanced and retreated, the valley was carved due to the contact between rock and ice.
How does the granite domes of Yosemite national park were formed?
In the 1800s, there was great controversy on whether Yosemite Valley was formed from water erosion, glaciation, or volcanic cataclysm. In the early 1900s, evidence for glaciation became overwhelming.
Glaciation effects on interior plains?
Glaciation on interior plains can create unique landforms like drumlins, eskers, and outwash plains. The movement of glaciers can shape the landscape by depositing sediment and carving out valleys. Glaciation also leads to the formation of lakes and wetlands in the region.
How do you make a valley out of playdo?
you shape it into a valley
How can you use the term glaciation in a sentence about the great lakes?
The Great lakes went through glaciation many thousands of years ago.
What is the shape of a valley left behind by a glacier?
The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
