The Antarctic Mountains are a major mountain range located in Antarctica, stretching over 3,500 kilometers (about 2,200 miles) across the continent. These mountains are primarily composed of rock and ice, with some peaks reaching elevations of over 4,500 meters (14,800 feet). The range is divided into several subranges, including the Ellsworth Mountains and the Transantarctic Mountains. These mountains play a crucial role in the Antarctic ecosystem and climate. They influence weather patterns and serve as a barrier to ice flow, affecting the stability of the Antarctic ice sheet. The harsh conditions in this region make it one of the most remote and least explored areas on Earth.
