Antarctica is not 'split up'. The surface of the continent is trans-sected by the Trans-Antarctic Mountain Range, and often this demarcation separates east from west Antarctica.
Nation-states have laid claim to Antarctic territory, in pie-shaped 'slices' that follow lines of longitude, all of which converge at the South Pole. Some of these claims overlap each other The Antarctic Treaty acknowledges all claims and holds them in abeyance, and prohibits future claims.
You may be thinking of the Trans-Antarctic mountain range that divides east and west Antarctica.
You may be thinking of the Trans-antarctic Mountains.
You may be thinking of the Trans Antarctic mountain range.
You may be thinking of the Trans-Antarctic mountains.
The Transantarctic Mountains divide Antarctica into eastern and western regions. These mountains stretch across the continent and act as a physical barrier, separating the coastal regions from the interior of Antarctica.
Antarctica is a continent of approximately 14,000,000 sq km. The Transantarctic Mountains divide Antarctica into east and west. East Antarctica constitutes the bulk of the land mass and is the oldest part of the continent. West Antarctica is the newer and smaller area which includes the Antarctic Peninsula and consists of four land areas separated by deep water.
The Antarctic is divided, east and west, by the Transantarctic Mountain Range.
The Transantarctic Mountain range is not one single mountain but a long, continuous range of mountains that divides East Antarctica from West Antarctica. The highest peak in this range is Mount Kirkpatrick, which is 14,526 feet (4,428 meters) tall.
The Transantarctic Mountain Range stretches from Victoria Land on the Ross Sea to the Rockefeller Plateau in the interior of Antarctica. It divides East Antarctica from West Antarctica and is one of the longest mountain ranges in the world, with peaks exceeding 14,000 feet.
The Prime Meridian effectively divides the continent of Antarctica in half. Since prime meridians are arbitrary this is based on the Greenwich Prime Meridian.
First the nucleus divides. Then the cytoplasm divides.
The prime meridian passes through Europe, Africa, and Antarctica. It serves as the starting point for measuring longitude and divides the Earth into Eastern and Western Hemispheres.
