A glacier forms when winter snowfall in an area exceeds summer melt and therefore accumulates year after year. Snow is compacted and converted to glacial.

Glaciers: Rivers of Ice

Bering Glacier, Alaska

How do glaciers form?

Snow accumulation > Snow melt

Layers of snow accumulation, density changes.

Crystals start to form.

Snow under compression --- Ice crystals result.

Dense (compacted, crystallized) glacial ice looks blue.

How do glaciers flow like rivers?

Cool Glacier Facts Glaciers cover 15 million square kilometers of the Earth’s land surface. About three-quarters of Earth’s freshwater is in glaciers. The world’s largest glacier today is the ice sheet that covers East Antarctica, which in places is over 4200 meters thick. The world’s longest glacier today, the Bering Glacier in Alaska (US), is 204 kilometers long.
