Atmospheric processes in Polar Lands includes wind forming and ice shaping. When there are calm winds ice grows, when there are strong winds, it shapes the ice into flat or irregular structures.
Biotic processes involves living organisms. Animals like polar bears, seals and whales have an effect on the environment because of its food chain. Fish eat krill, seals eat fish, polar bears eat seals. The whole polar ecosystem revolves around different food chains.
Geomorphic processes include tsunamis and earthquakes. These change polar environments as they cause destruction to ice sheets,wreck habitats and food sources.
