Glaciers
Body of dense ice that only forms on land.
Ice Sheets
Masses of glacial ice that are each greater than 20,000 square miles in area
Ice Shelf

Sea Ice
Frozen seawater that floats of the ocean surface, primarily found in the Northern hemisphere.
Oceanic Circulation
Event where heat is transferred to the equator by ocean currents.
Great Ocean Conveyor Belt
