Answer:
If the climate and the position of a place are relative to each other, then the initial location of Antarctica 250 million years ago is in Gondwana Subcontinent
. Gondwana Subcontinent is one of the two subcontinent of Supercontinent called Pangea. And around 280 to 230 million years ago, the Pangea started splitting.
Explanation:
According to the experts Pangaea or Pangea was a supercontinent that broken into two subcontinent. The continents today was a product of continuous continental shifts and movements. These all-in-one supercontinents includes Columbia (Nuna), Rodinia, Pannotia and Pangaea.
Around 280 million to 230 million years ago, Pangaea started splitting. Part of the process was Pangaea cracked into northernmost and southernmost subcontinents. The northern landmass was called Laurasia comprises the now continents of Europe, Asia and North America. Gondwana was half of the Pangaea, the southern landmass opposite to Laurasia. Gondwana includes Africa, South America, Australia, Antarctica, Indian subcontinent and Arabian Peninsula.
During the Gondwana supercontinent, the planet was warmer and there was no Antarctica ice sheet. It was covered with lush rainforest and dinosaurs were roaming the Earth. And by around 170 million and 180 million years when Gondwana began its own split.
There are theorists that believes in the "hot spots", where the magma is close to the surface, bubbled up and rifted the supercontinent apart. However in 2008, University of London researchers suggested that Gondwana splitted into two tectonic plates that broke them apart.
