Sharp ridges separating glacial valleys?
Aretes
What are some features of a unwarped mountain?
Unwarped mountains typically have high peaks with sharp ridges.
What are the main features of a mountain?
Mountains have several features. They have steep sides and sharp ridges and peaks. They are rocky and barren, and usually have snow on them.
Why do you hear a sharp crack from thunder when it is close?
The sharp crack you hear from thunder when it is close it the electricity in the air.
What rock is actually glass and has sharp edges?
Obsidian is a natural volcanic glass with potentially sharp fracture edges.

Aretes
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?
Glacial landscapes are typically characterized by U-shaped valleys, sharp ridges, and moraines deposited by glaciers. Water-formed landscapes, on the other hand, exhibit features like V-shaped valleys, meandering rivers, and deltas. Glacial landscapes often have more angular and rugged terrain compared to the smoother and more rounded features of water-formed landscapes.
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.
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 features are formed by ice erosion?
Ice erosion can create features such as cirques (bowl-shaped hollows on mountainsides), arêtes (sharp ridges between two cirques), and horns (sharp peaks formed by glaciers eroding multiple sides). These features are commonly found in glaciated mountainous areas.
How is an arete formed?
An arête is a thin ridge of rock which is formed when two glaciers erode parallel U-shaped valleys. The arête is a thin ridge of rock that is left separating the two valleys Arêtes can also form when two glacial cirques erode head wards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering. Where three or more cirques meet, a pyramidal peak is created. - (a famous example is the 'Matterhorn'). Form the above it must be clear that arêtes are landforms found in mountainous terrains that have been subject to glaciation. They are therefore very common in the Alps.
True or false Sharp jagged peaks are characteristic of fault-blocked mountains.?
False. Sharp, jagged peaks are more characteristic of fold mountains, which are formed by the folding of rock layers under pressure. Fault-blocked mountains tend to have more linear ridges and valleys due to the movement of large fault blocks along fault lines.
What are some features of a unwarped mountain?
Unwarped mountains typically have high peaks with sharp ridges.
What is a sharp pyramid-shaped peak that forms when three or more cirques erode a mountain?
Glacial horn
Do young fold mountains have rugged relief features?
Yes, young fold mountains typically have rugged relief features such as steep slopes, deep valleys, and sharp ridges. These features are a result of the tectonic forces that created the mountains and the erosion processes that shape the landscape over time.
