This helps in understanding that Antarctica was once located in the tropical region, where a large number of trees were present, which were died and buried under the soil and rocks, and as the tectonic plates are continuously moving from one place to another, so Antarctica has now reached the south pole of the earth.
Antarctica is found to be comprised of fossilized trees in its rocks. These trees were deposited long time back in the geological time scale. They are often found to be comprised of coal beds.

The presence of this fossilized trees gives an idea of how plates move from one location to another around the globe.
1. gravity keeps the water moving downward or just in general 2. the water has to move across the surface for so long till eventually it just erodes away. those are the only two i know sorry.
