Polar regions of the Arctic and Antarctic are unique. There is less solar radiation to warm the ice and ground. Their location on the earth results in a frozen environment. Temperatures don't often rise above freezing.
The Arctic is made up mostly of ice caps, ice sheets and glaciers. An ice sheet covers Antarctica. The Arctic area is mostly floating ice. The Antarctic is mostly a sheet of ice covering land. These areas are considered marine biomes because they are covered with ice and get their life and energy from the surrounding oceans.
