Glacier Movement

Study Notes

Glacier Movement

Basal sliding is the most common process by which glaciers move.
Basal sliding is the movement of a glacier over its bed due to meltwater reducing friction.
Crevasses are large cracks or fissures that form on the surface of glaciers.
Crevasses form because of the different speeds of glacial ice at the surface and at its base.
Glaciers move under the influence of gravity and due to their own weight.
Glacier flow rate can be increased by factors such as slope, temperature, and the amount of meltwater.
The slowest glaciers can move at rates of less than a meter per year.
The fastest glaciers can move at rates of up to several kilometers per year.
Crevasses are dangerous to hikers and climbers because they are hidden by snow and can be fatal if fallen into.

Glaciers Formation

Glaciers are large masses of ice that form over time, often in mountainous regions.
Glaciers are created when snow accumulates over a long period and is compressed into ice.
Glaciers can be formed when enough snowfall exceeds melting and evaporation.
Glaciers have a significant impact on the Earth's surface, shaping landscapes and creating landforms.

Glacier Impact

Glacier movement carves out valleys and shapes mountains.
Glaciers can erode the bedrock and carry sediment, leaving behind deposits of glacial till.
Glaciers are sensitive to changes in climate and are retreating rapidly in many parts of the world.
Glacier retreat has consequences for water resources, coastal communities, and ecosystems.
