A glacier is a huge body of ice that moves slowly because of it’s large mass and weight, it is usually 91 to 3,000 meters thick.
How it's made
A glacier is formed in the polar regions in a mountain. It forms by low temperatures that turn snow into ice which eventually create ice pellets. Soon the pellets will clump together and make ice crystals that will create glacial ice. Finally it will make a glacier that will move because of it’s own weight.
Scientists are finding out that glaciers can help them see how much the earth usually warms up in between ice ages and how much human activity is affecting climate change.
People living in La Paz, Bolivia use water from a melting glacier when they go through a drought period.
Compare and Contrast
The difference between an ice shelf and a glacier is that a glacier is on land but an ice shelf is floating on water. Also you can only find ice shelves in Antarctica, Greenland, Canada but a glacier is found on every continent.Some things that are the same between an ice shelf and glacier is that they are both made of ice and both move because of gravity.

Here you can sort of see the layers of the glacier.
