Glacial valleys form through the process of glacial erosion, where the movement of a glacier carves and shapes the valley over time. As the glacier moves downhill, it picks up rocks and sediments, which act as abrasives that wear away the underlying rock. The downward pressure and friction of the glacier further deepen and widen the valley, creating a distinct U-shaped profile.

What are flooded glacial valleys?
Flooded glacial valleys are valleys carved out by glaciers during the last Ice Age which are now submerged under water. These valleys can form deep fjords, where seawater has filled in the glacially-carved depressions. Examples include the fjords of Norway and Alaska.
Sharp ridges separating 2 glacial valleys?
These sharp ridges are called aretes and form when glacial erosion carves out valleys on either side of the ridge. As glaciers move down the valleys, they erode the rock on both sides, sharpening the ridge. Aretes are a common feature in glaciated regions like the Alps or Himalayas.
A sentence for glacial erosion?
Glacial erosion occurs when moving ice wears away at rock and soil, shaping the landscape by carving out valleys and forming unique landforms like cirques and aretes.
Where can you find glacial moraines?
Glacial moraines can be found in regions that have experienced glaciation, such as near the edges of glaciers, in valleys or along mountain slopes where glaciers have left behind deposits of rocks, soil, and debris. These deposits form distinct ridges and mounds that are characteristic of glacial moraines.
Ice erodes rock and deposits sediments to form?
Glacial ice erosion will form: * Corries (cirques) * Aretes * Pyramidal Peaks * U-shaped troughs * Hanging Valleys * Truncated Spurs * Rouche Moutonees * Striations * Rock Steps Sediment deposition (resulting from glacial processes) will form: * Ice-transported boulders * Erratics * Lateral moraines * Medial moraines * Terminal moraines * Recessional moraines * Push moraines * Varves * Eskers * Delta kames * Kame terraces * Braided streams * Flat bottoms to U-shaped valleys
Do hills form from glacial erosions?
Well really the valleys BETWEEN hills form by glacial and/or other erosion. The hills are what's left behind.
What are flooded glacial valleys?

Which glacial landforms require more than one glacier to form?
aretes,hanging valleys,horns,and drumlins
Glacial valleys shaped differently from river valleys?
u shaped valley..
What shape valley does a glacier leave?
Glacial valleys (also known as glacial troughs) tend to be u-shaped, as opposed to river valleys which are v-shaped.
How are glacial valleys straightened?
Glacial valleys can be straightened through a process called glaciation. As glaciers move down valleys, they can reshape them by eroding and bulldozing material, creating straighter and smoother profiles. This process is known as glacial erosion and can result in the formation of U-shaped valleys.
The flooded glacial valleys of Scandinavia are known as?
Fjords.
Sharp ridges separating 2 glacial valleys?
These sharp ridges are called aretes and form when glacial erosion carves out valleys on either side of the ridge. As glaciers move down the valleys, they erode the rock on both sides, sharpening the ridge. Aretes are a common feature in glaciated regions like the Alps or Himalayas.
Are glacial valleys you shaped?
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.
What is a glacial Areté?
Sharp narrow ridge separating two glacial troughs (U-shaped valleys), or corries.
