A U-shaped valley begins as a V-shaped river valley. If the temperature is low enough, a glacier (river of ice) forms inside the valley. As the glacier slowly moves, it scours the valley floor when the temperature rises and the glaciers melts away, a U-shaped valley is left behind.

Do glaciers fill valleys?

It does!


What caused the valley to form?

Valleys can form through processes like erosion by rivers, glaciers, or tectonic activity. For example, rivers may erode the land over time, creating a valley. Glaciers can also carve out valleys as they move across the landscape. Tectonic processes like faulting or folding can create valleys as well.


What landforms are created by glaciers and how?

Glaciers create various landforms such as U-shaped valleys, moraines, drumlins, and fjords through processes like erosion, deposition, and melting. For example, as glaciers move, they erode the land beneath them, forming U-shaped valleys. When glaciers retreat, they leave behind piles of debris called moraines. Drumlins are elongated hills formed by glaciers depositing sediments, and fjords are deep, narrow inlets created by glaciers moving through valleys and subsequently melting.


How do glaciers make valleys?

The glaciers rubs against the land form which changes the land form into a U shape valley this works because the ice is so packed it pushes any land as in dirt sand and minerals out the way creating the valley


Why do glaciers form U-shaped valleys rather than V-shaped valleys?

Glaciers form U-shaped valleys due to their ability to erode and transport large amounts of rock and sediment. As glaciers move downhill, they carve and widen the valley floor, creating a broad and deep U-shaped profile. In contrast, rivers mainly erode the valley through the process of hydraulic action, which tends to create narrower and steeper V-shaped valleys.
