Polar mountains are found in the Arctic and Antarctic regions, characterized by their rugged terrain and extreme weather conditions. These mountains are often covered in ice and snow, making them inhospitable for most forms of life. The landscape is shaped by glacial activity, which carves out valleys and creates sharp peaks. In the Arctic, notable ranges include the Brooks Range in Alaska and the Trollheimen in Norway. In Antarctica, the Transantarctic Mountains divide East and West Antarctica. These mountains play a crucial role in the Earth's climate system and are important for scientific research related to climate change.
