WebGlaciers in temperate zones tend to move the most quickly because the ice along the base of the glacier can melt and lubricate the surface. Other factors that affect the velocity of a … WebMost lakes in the world occupy basins scoured out by glaciers. Glacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) [1] or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d).

WebThe characteristic flow it has is due to pressure on ice crystals to deform plastically and flow downslope. Basal sliding occurs due to forming meltwater. Meltwater serves as a lubricant for easier sliding. This allows for the fastest movement of glacial ice at surface. Objectives: Determine the factors that affect the motion of glaciers.
