* Marie Byrd Land: This is the largest subregion of West Antarctica and is known for its vast ice sheet and relatively flat terrain.
* Ellsworth Land: Located to the east of Marie Byrd Land, Ellsworth Land features the highest peaks in Antarctica, including the Sentinel Range and the Vinson Massif.
* Queen Maud Land: While technically a part of East Antarctica, the eastern portion of Queen Maud Land is sometimes considered a part of West Antarctica due to its proximity to the Transantarctic Mountains.
* Antarctica Peninsula: This is the northernmost part of West Antarctica, extending towards South America and experiencing relatively warmer temperatures.
It's important to note that the division between East and West Antarctica is based on the Transantarctic Mountains, not purely geographical coordinates. This means there can be some overlap, especially when discussing regions like Queen Maud Land.
