Glaciers move by extrusion flow. This involves two main processes; internal deformation and basal sliding.
Internal Deformation
Under the immense weight of overlying ice, individual ice crystals align into layers and slide over each other. (Much like the property of metal ions which leads to the characteristic of maleability).
Basal sliding
Meltwater (from pressure melting) lubricates the base of the glacier, which slides over the bedrock under the influence of gravity.
What else can I help you with?
Where do you find alpine glaciers?
The alpine glaciers are high in the mountains.
How do alpine glaciers form?
Alpine glaciers form when snow accumulates in a mountain valley and compacts over time into ice. The weight of the ice causes it to flow downhill, carving out the valley and creating a glacier. Cold temperatures and consistent snowfall are necessary to sustain an alpine glacier.
How do you describe the landscape made by alpine glaciers compared to the landscape by continental glaciers?
Alpine glaciers leave behind U-shaped valleys, deep, high-altitude lakes and cliffs. Continental glaciers flow outwards scraping the landscape clean, making fairly flat lands and lakes
What kind of glaciers are Antarctica and Alpine?
Antarctica is a continental glacier. Alpine glaciers are a different type of glacier.
What type of glacier forms in a mountain area?
alpine glaciers
What are glaciers formed in mountains called?
Glaciers formed in mountains are called mountain glaciers or alpine glaciers. They are found in high-altitude regions and flow downhill through valleys.
How are glaciers different from alpine glaciers?
They difference between them is where there flow. Continental glaciers are enormous ice sheets, and are found in Greenland and Antarctica. Alpine glaciers form in mountain valleys.
What are 5 ways that alpine glaciers are different from continental glaciers?
Alpine glaciers are smaller in size and are found in mountainous regions, while continental glaciers cover much larger areas of land. Alpine glaciers move down valleys, while continental glaciers flow outwards in all directions from a central ice dome. Alpine glaciers are influenced by local topography and weather conditions, while continental glaciers are influenced by global climate patterns. Alpine glaciers tend to have higher melt rates due to their lower elevation compared to continental glaciers. Alpine glaciers are more accessible for study and research compared to the remote and harsh environments of continental glaciers.
Where do you find alpine glaciers?
The alpine glaciers are high in the mountains.
What are the 2 types of glacier erosien?
Glaciers are ice sheets. There are 2 kinds of glaciers: alpine glaciers and continental glaciers. Alpine glaciers are formed when valleys above the snow line fill with ice and snow. Snow is compacted and gradually begins to flow downhill due to gravity. -Cham11
What the 2 most common kinds of glaciers?
There are 2 main types of glaciers, Continental is one, they float away from central regions. The second is alpine or valley which are the glaciers that flow down the valley from the mountain.

What kind of glaciers are Antarctica and Alpine?
Antarctica is a continental glacier. Alpine glaciers are a different type of glacier.
Why do continental glaiciers smooth the landscape and alpine glaciers create a rugged landscape?
Continental glaciers are larger and flow over vast regions, leading to erosion and smoothing of the landscape. Alpine glaciers are smaller and flow through steep mountain valleys, resulting in more specific and localized erosion that creates a rugged landscape with sharp peaks, cirques, and ridges.
What are the two kinds of glaciers and how are they different?
The two main types of glaciers are alpine glaciers, which form in mountainous regions and flow down valleys, and ice sheets, which are massive continental glaciers that cover large areas of land. Alpine glaciers are smaller and more common, while ice sheets are much larger and thicker.
What is the difference between alpine and continental glaciers?
Alpine glaciers form in mountainous regions and are confined within valleys or cirques, while continental glaciers are large ice sheets that cover vast land areas. Alpine glaciers are typically smaller and more fragmented compared to the continuous ice sheets of continental glaciers.
