What are the rounded basins carved into the sides of mountains by valley glaciers?
Cirques are the rounded basins carved into the sides of mountains by valley glaciers. They are typically characterized by steep walls and a bowl-like shape. The process of glacial erosion forming cirques is known as plucking and abrasion.
How do glacier horn form on a mountain?
Ussually by three cirques A cirque is an origin point for glaciers in mountainous areas. It is a deep depression with three high walls and an open area from which the glacier moves forward, down the mountain side. Over time, as rock is eroded, these become wider and deeper. A mountain horn, such as the Matterhorn in the Alps forms when a peak is surrounded on two or more sides by cirques. As the cirques expand and rock is eroded the peak is honed into a point, forming a horn.
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 landform is created when glaciers erode backwards into the mountainside and form a shape like a shallow bowl?
The landform created when glaciers erode backwards into the mountainside, resulting in a shape like a shallow bowl, is called a "cirque." Cirques are typically found at the head of a glacial valley and are characterized by steep cliffs on three sides and a gentle slope on the fourth, where the glacier may flow out. Over time, if the cirque fills with water, it can form a tarn, which is a small mountain lake.
Are continental glaciers larger than valley glaciers?
Yes. A continental glacier spreads around all sides, while the valley glaciers spread along it's length.
What are the rounded basins carved into the sides of mountains by valley glaciers?
Cirques are the rounded basins carved into the sides of mountains by valley glaciers. They are typically characterized by steep walls and a bowl-like shape. The process of glacial erosion forming cirques is known as plucking and abrasion.
What can create cirques on the sides of mountains?
A cirque is the top of a glacier valley.

What land features are formed from ice erosion?
Land features formed from ice erosion include cirques, u-shaped valleys, and fjords. Cirques are bowl-shaped depressions at the head of a glacier, u-shaped valleys are deep valleys with steep sides carved out by glaciers, and fjords are long, narrow inlets with steep cliffs created by glaciers flowing into the sea.
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.
When 2 cirques on opposite sides of a valley meet what do they form?
Moraine
What are three glacial landscape features?
Cirques: bowl-shaped hollows formed at the head of a glacier where snow and ice accumulate. Moraines: ridges of glacial debris, such as rocks and sediment, deposited along the sides or at the terminus of a glacier. U-shaped valleys: valleys carved by glaciers that have distinctive steep sides and flat bottoms.
A sharp pyramid shaped peak tat forms when three or more cirques erode a mountain?
The sharp pyramid-shaped peak formed by the erosion of three or more cirques on a mountain is called a horn. This landform is typically created by the intersection of multiple glaciers eroding the mountain from different sides, resulting in steep, jagged peaks. Famous examples include the Matterhorn in the Swiss Alps.
What agents of erosion form U -shaped valleys?
Glaciers are the main agents of erosion that create U-shaped valleys. As glaciers move downhill, they carve out the valley floor and sides through the process of abrasion and plucking. The unique U-shape is a characteristic feature of valleys that have been shaped by glaciers.
Does glaciers always melt from the sides first?
Not always but
What do the presence of waterfalls on sides of mountains reveal?
Waterfalls on the sides of mountains reveal much about hydrology.
What are the four major types of landforms found on earth?
The four major types of landforms found on Earth are mountains, plains, plateaus, and valleys. Mountains are elevated landforms with steep sides, while plains are flat expanses of land with minimal elevation changes. Plateaus are elevated flatlands, often with steep cliffs on one or more sides. Valleys are low-lying areas between hills or mountains, often carved by rivers or glaciers.
