WebbPlucking - This is the main erosive process of a glacier. As the glacier moves along the valley the ice melts slightly around large boulders, before re-freezing around them. As it then moves on the boulders are literally ripped out of the ground and will often become agents of abrasion. Freeze-Thaw - Water enters cracks in the rock during the day.

A glacier is formed as snow accumulates over time and turns to ice, a process that can take more than a hundred years. Once a glacier has formed, it moves very slowly, at a rate of years, or even decades; some glaciers are frozen solid and do not move at all. The world’s fastest … debug font download

Plucking takes place by water entering cracks under the glacier, freezing, and breaking off pieces of rock that are then transported by the glacier.

Glaciers are effective agents of erosion, especially in situations where the ice is not frozen to its base and can therefore slide over the bedrock or other sediment. The ice itself is not particularly effective at erosion because it is relatively soft (Mohs hardness 1.5 at 0°C); instead, it is the rock fragments embedded ...
