What are the two different types of glacial erosion?

Glacial erosion is caused by two different processes: abrasion and plucking (see above).

What are the 4 types of glaciers?

What types of glaciers are there?

• Mountain glaciers. These glaciers develop in high mountainous regions, often flowing out of icefields that span several peaks or even a mountain range.
• Valley glaciers.
• Tidewater glaciers.
• Piedmont glaciers.
• Hanging glaciers.
• Cirque glaciers.
• Ice aprons.
• Rock glaciers.

What is an example of glacial erosion?

Glacial lakes are examples of ice erosion. They occur when a glacier carves its way into a place and then melts over time, filling up the space that it carved out with water. The valley was home to glaciers for much of a 30 million year period, which caused its deep cut into the landscape.

What are 2 features of glacial erosion?

U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins. Varves are a very useful yearly deposit that forms in glacial lakes.

What two main types of glacial erosion are abrasion and?

Glaciers cause erosion in two main ways: plucking and abrasion.

• Plucking is the process by which rocks and other sediments are picked up by a glacier. They freeze to the bottom of the glacier and are carried away by the flowing ice.
• Abrasion is the process in which a glacier scrapes underlying rock.

How many types of glacial landforms are there?

As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.

What are 3 types of glaciers?

Glaciers are classifiable in three main groups: (1) glaciers that extend in continuous sheets, moving outward in all directions, are called ice sheets if they are the size of Antarctica or Greenland and ice caps if they are smaller; (2) glaciers confined within a path that directs the ice movement are called mountain …

How many different types of glaciers are there?

17.1 Types of Glaciers. There are two main types of glaciers: continental glaciers and alpine glaciers. Latitude, topography, and global and regional climate patterns are important controls on the distribution and size of these glaciers.

What are the types of erosion?

The main forms of erosion are:

• surface erosion.
• fluvial erosion.
• mass-movement erosion.
• streambank erosion.

What is glacial abrasion?

Abrasion: The ice at the bottom of a glacier is not clean but usually has bits of rock, sediment, and debris. It is rough, like sandpaper. As a glacier flows downslope, it drags the rock, sediment, and debris in its basal ice over the bedrock beneath it, grinding it.

Which type of landforms are produced by Glacier?

Glacier Landforms

• U-Shaped Valleys, Fjords, and Hanging Valleys. Glaciers carve a set of distinctive, steep-walled, flat-bottomed valleys.
• Cirques.
• Nunataks, Arêtes, and Horns.
• Lateral and Medial Moraines.
• Terminal and Recessional Moraines.
• Glacial Till and Glacial Flour.
• Glacial Erratics.
• Glacial Striations.

What factors affect glacial erosion?

Terms in this set (7)

• Type of glacier. …
• Thickness of ice. Thicker the ice – the more pressure exerted on the bed – bed rock more likely to tear away.
• Hardness of tools. Glaciers accumulate debris on their bases which aid with abrasion.
• Quantity of load.
• Quantity of meltwater.
• Strength of bedrock.
• Permeability of rock.
