How are they made?
A glacier begins when snow doesn’t completely melt away during the summer. Each with new snow falls on top of the old snow. Thick layers of snow are gradually compressed into glacial ice.
Glaciers grow and shrink in response to climate

Glaciology - the study of glaciers Glaciologist - a scientist who studies glaciers Glaciers- Huge masses of ice Ice Calving- the sudden release and breading
away of a mass of ice from the glacier Iceberg- A huge chunk of ice floating in the
ocean they come in small, medium, and large. Snout - the end of a glacier Firn - older snow

Facts! 10% of land on Earth is
covered with glacial ice Glaciers store about
75% of the world's freshwater.
During the last ice age, glaciers covered 32% of the total land area.
• The tallest known iceberg in the North Atlantic was 550 feet (168 m) above sea level.
