A glacier is a system . There is a zone of accumulation where snow is added. This is normally at the start of a glacier in a highland area. As more and more snow falls, it is compacted so the bottom layers become ice. Ice moves downhill due to the force of gravity.
What are glaciers GCSE?

This means that the snow that accumulates in the winter and isn’t lost by melting or evaporation during the summer. These conditions occur in polar and high alpine regions.

What are glaciers Class 7?
Glaciers: Glaciers are “rivers of ice” which erode the landscape by bulldozing soil and stones to expose the solid rock below. Glaciers carve out deep hollows there. As the ice melts they get filled up with water and become beautiful lakes in the mountains.
What is the importance of glaciers?
Glaciers provide people with many useful resources. Glacial till provides fertile soil for growing crops. Deposits of sand and gravel are used to make concrete and asphalt. The most important resource provided by glaciers is freshwater.
