The top of a glacier moves faster than the bottom because of the effects of gravity. As the glacier flows downhill, the ice at the top is able to slide over the layers beneath it, causing it to move quicker. This phenomenon is known as internal deformation.

glaciers move slowly but when theres alot of rain the water and the glaciers move faster


Which parts of glaciers and its triburitaries moves most quickly?

Glacier speed is not constant across the glacier. The top half of the glacier moves faster than the bottom, presumably because of friction. The sides also flow slower than the middle, also because of friction. The middle of the glacier at the equilibrium line flows fastest, the head and terminus flow slower. Above the equilibrium line the glacier grows faster than it melts; this is called the accumulation zone. Below the equilibrium line, the glacier melts faster than it grows; this is called the ablation zone.


Where does glacier ice move quickly and slowly within a glacier?

Glacier ice moves more quickly in the center of the glacier where there is less friction with the valley walls. It moves more slowly along the sides and bottom of the glacier where there is more friction with the rock and sediment beneath it.


2 What does it mean to say a glacier is retreating?

The glacier is melting faster than it is sliding down the valley.


What is the lower end of a glacier called?

The area that is melting faster than it is accumulating is the "Zone of Ablation." The very bottom end of a glacier is typically called its "foot."


When new snow is added to a glacier faster than ice and snow melt does the glacier get larger or smaller?

When new snow is added to a glacier faster than the rate at which ice and snow melt, the glacier gets larger because the accumulation of new snow exceeds the loss from melting. This process contributes to glacier growth and expansion.


Which part of valley glacier moves the fastest?

The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.


How do glacier move?

They melt and then slide


When do glaciers appear to move backwards?

Glaciers appear to move backwards when they experience a process known as glacier surging. This occurs when the glacier advances at a significantly faster rate than usual, causing the ice to flow back uphill in certain areas. Glacier surging is relatively rare and can be triggered by various factors, including changes in temperature and water pressure.


What in solids move faster than in liquids?

Sound will usually move faster in a solid than in a liquid.

What is advancing glacier?

A Glacier will advance when the snow deposited in the collection zone exceeds the rate of melting at the terminus. There will be some time delay between these events, even a steep glacier will take a few years between the events.
