Polar climates are known for extremely cold temperatures year-round and minimal precipitation, often in the form of snow.

Polar climates are defined by extremely cold temperatures throughout the year, with long, harsh winters and short, cool summers. Precipitation is scarce, typically falling as snow, and is often less than in more temperate or tropical climates. This lack of rainfall and the frigid temperatures create a harsh environment where only specially adapted plants and animals can survive. The cold temperatures cause most of the precipitation to freeze, leaving little water available for plant growth. These conditions are found in the Arctic and Antarctic regions, where ice and snow dominate the landscape year-round.
