Glaciers are formed when snow accumliates over a long period of time, often in a hollow. As the snow builds up the pressure builds up causing the snow to compact so much it is turned to ice.

The ice only becomes a glacier when it starts to move, usually this movement is due to gravity.

There are two types of glacier, valley glaciers and ice sheets. As you can imagine valley glaciers are formed in valleys where a river has frozen. These can often lead to the formation of ribbon lakes, hanging valleys, U-shaped valleys and truncated spurs.

Ice sheets are simpley large glaciers that can be anywhere, some are small, others are the soze of continents. As they move they can cause plucking and abrasion. As well as this they can cause corries and drumlins, amongst other things.
