They melt and then slide
A continental glacier can move in all directions and a valley glacier can move in a surge. :)

There are three nouns. They are pressure, weight, and glacier.
the glacier picks up the sediments, rocks, till, debris, and soil and carries them along while the glacier moves and will eventually drop them.
Gravity
Antarctica is a continent, not a glacier, and has only ever moved south.
The glacier can carry rocks. The moving of the 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.
glaciers move slowly but when theres alot of rain the water and the glaciers move faster
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.
The time it takes for a glacier to move 1,000 meters varies significantly depending on factors like the glacier's thickness, slope, temperature, and the underlying terrain. On average, glaciers move at rates ranging from a few centimeters to several meters per day. Therefore, it could take anywhere from a few years to several decades for a glacier to cover 1,000 meters. For example, if a glacier moves at 1 meter per day, it would take approximately 1,000 days, or about 2.7 years, to cover that distance.
An example of a fast-moving glacier that can move up to 6 kilometers per year is the Jakobshavn Glacier in Greenland. It is known for its rapid movement and has been experiencing accelerated ice loss due to climate change.
