What is a glacier?
Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses.
How is a glacier formed?
Glaciers begin to form when snow remains in the same area year-round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers.
Why do glaciers move?
Once the ice gets too thick the weight makes the glacier slowly began to move.
Where are glaciers located?
Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
How do glaciers affect the land?
laciers not only transport material as they move, but they also sculpt and carve away the land beneath them. A glacier's weight, combined with its gradual movement, can drastically reshape the landscape.
