Glaciers ! By: Jessica Chandler
2
What is a glacier? A glacier is a large mass of compacted snow and ice that moves under the force of gravity.
3
What are the two types? The first type of glacier is the valley glacier; which is a glacier that moves within valley walls. The second type of glacier is the continental glacier; which is a glacier that covers a large part of a continent.
4
How do glaciers move? They move by the slipping of the water that is being squished under all of the snow.
5
Why did Ice Ages occur in the past? One theory of why Ice Ages occurred is that a volcano erupted and that spread ash every where which caused less sunlight and that caused a year of cold and snow which caused glaciers.
