The Transantarctic Mountains are a major mountain range in Antarctica, stretching over 3,500 kilometers (2,200 miles) from the Ross Sea to the Weddell Sea. This range divides East Antarctica from West Antarctica and is characterized by rugged peaks and deep valleys. The mountains are primarily composed of ancient rocks and are covered by ice and glaciers. These mountains play a crucial role in the Antarctic ecosystem, influencing weather patterns and glacial movements. The highest peak in the range is Mount Vinson, which reaches an elevation of 4,892 meters (16,050 feet). The Transantarctic Mountains are also significant for scientific research, providing insights into Earth's geological history.
