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.
What landforms are formed by glacial erosion?
Glacial erosion can create landforms such as cirques (bowl-shaped depressions), arêtes (sharp ridges), horns (peak), U-shaped valleys, and fjords (steep-sided inlets). These features are typically found in areas where glaciers have passed through and reshaped the landscape over time.
What are effect of glaciation in the western cordillera?
Glaciation in the Western Cordillera has influenced the landscape by creating steep valleys, sharp peaks, and U-shaped valleys. Glacial erosion and deposition have shaped the region's topography, leaving behind moraines, cirques, and other glacial landforms. The presence of glaciers also impacts the local climate, hydrology, and biodiversity in the region.

What landforms does glacial erosion create?
Two major erosional processes occur at the base of a glacier. First, at the base of a glacier, large amounts of loose rock and sediment are incorporated into the moving glacial ice by partial melting and refreezing. The second process of erosion involves the abrasive action of the held rock and sediment held by the ice on the surface underneath the glacier. This abrasive process is known as scouring.

What is a glacial Areté?
Sharp narrow ridge separating two glacial troughs (U-shaped valleys), or corries.
How are glacial landscapes different from landscapes formed by water?
Water cuts V-shaped valleys; glacierscarve out valleys that are U-shaped.-THIS IS TRUE.GRADPOINT/NOVANET ;) :) jesstyn wise ps3-jesstynwise ig-billgates217 fb-jesstyn wise

What is a mountain ridge that separates the heads of opposing glacial valleys called?
A mountain ridge that separates the heads of opposing glacial valleys is called an arete. It is a narrow and sharp ridge formed by the erosive action of glaciers on both sides.
What are Land forms created by a glacier?
terminal moraines--------------------------------------------------------------------------------------------------------They can be:Cirques, bowl-shaped depressions where glacial ice cuts back into the mountain walls.Horns, sharp, pyramid-like peaks that form when three or more alpine glaciers carve a mountain.Arête, a jagged ridges that form between two or more cirques that cut into the same mountain.Also U-shaped valleys and Hanging Valleys.
Erosional features produced by alpine glaciers?
Alpine Glacier produce a variety of erosional features. These features are usually rounded or polished grooves made by the glacier's passing. The features are called arete, Circque, horn, tarn, u shaped valley, and hanging valleys.

What clues would you look for to determaine if you were in an area that was oncee covered by glaciers?
Many topographical features may be the result of glaciers. Lakes, sharp ridges on mountains, and glacial striations are some examples of these.
What are moon valleys?
Moon valleys are geological formations typically found in arid or desert regions, characterized by unique landscapes with deep valleys, sharp ridges, and unique rock formations. They get their name from their resemblance to the surface of the moon due to their desolate and otherworldly appearance. Moon valleys are often popular tourist destinations known for their natural beauty and geological significance.
How does and arete form?
An arete forms through the process of glacial erosion, where glaciers carve sharp ridges and peaks in mountainous regions. As glaciers move, they erode the rock on either side, leading to the creation of steep, narrow ridges. The continuous action of freezing and thawing can further shape the arete, enhancing its distinctiveness. Over time, the combination of these geological processes results in the formation of a sharp, jagged ridge characteristic of aretes.
