This diagram shows how a glacier is formed and how it moves and changes.         a large amount of the snow falls on the top of a mountain. Because the temperature at the top of the mountain is very low, this snow never melts.          more snow falls on top of it, the snow turns to ice. Eventually, a lot of ice is packed together, and           it forms a glacier. the glacier becomes very heavy and it starts to move slowly down the mounrain.
