Basal ice is the layer of ice that forms at the base of a glacier or ice sheet, in direct contact with the underlying bedrock or sediment. This ice can be affected by pressure, temperature, and the presence of liquid water, which can influence its flow and stability. Basal ice often contains impurities and can play a crucial role in the dynamics of glacier movement, as it interacts with the substrate beneath. Its properties are essential for understanding glacial behavior and the responses of ice masses to climate change.

What factors control ice velocity?

Ice velocity is controlled by a combination of factors including topography, temperature, ice thickness, presence of meltwater, and basal conditions. For example, steeper slopes can increase ice velocity, while the presence of basal lubrication from meltwater can reduce friction and increase ice flow. Changes in any of these factors can impact ice velocity and contribute to glacier dynamics.

What is the Basal erosion?

Basal erosion is the process of wearing away or eroding the base or bottom of a landform such as a glacier or a cliff. It is typically caused by the movement of water, ice, or other agents at the base of the landform, leading to the removal of material and reshaping of the surface.


What is basal sliding?

In general, ice sliding across rock. Usually applies to glacial movement and its impact on the underlying ground.

What is the pressure causing ice layers to slid over each other called?

Basal slip occurs when the glacier rests on a slope. Pressure causes a small amount of ice at the bottom of the glacier to melt, creating a thin layer of water. This reduces friction enough that the glacier can slide down the slope. Loose soil underneath a glacier can also cause basal slip.

What are 3 types of glacier movement?

Three types of glacier movement are basal sliding, internal deformation, and flow. Basal sliding occurs when the glacier moves over a layer of meltwater at its base. Internal deformation involves the slow movement of ice crystals within the glacier. Flow refers to the overall movement of the glacier downslope due to gravity.
