Antarctica, which literally means ‘opposite of the Arctic’, lies around the SouthPole. It is surrounded by the Indian Ocean, Atlantic Ocean, and the Pacific Ocean, the southern extremities of which together form the Southern Ocean. The continent is almost circular in shape with a narrow piece of land extending northwards towards the southern tip of South America. The eastern part is bigger and is called Greater Antarctica. The smaller western portion is Lesser Antarctica. There are two broad inlets of water, namely the Weddell Sea and the Ross Sea. Mt Erebus, an active volcano, is located in the Ross Sea.
