Incoming solar radiation is almost double at the equator then at the poles, causing the water closer to the equator to be warmer. The heat difference also causes the oceans to swirl so the water that is around the equator will eventually end up at the poles and keep circulating around.
As tectonic plates move things like volcanoes and mountain ridges form. The plates converge causing new physical features to form. They can also move apart creating ridges.
