because it gets cold on the way.
Because the middle of the earths surface is the hottest on earth and the equator is right in the middle and the poles is at the end of the earths surfaces
the equator daaa
The heat transfers through the entire ocean, since its technically one big global ocean.
it is a mushed 3d sphere
The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles.
I'm not positive on this but I'm pretty sure. The equator is just warmer because the sun is shining brightest on it. The earth is round so the center of the earth or the equator is closer to the sun the tips or the north or south pole. Because the equator is warmer, the oceans are warmer too.
The temperatures at the equator tend to be warm to hot (except where there are mountains); the temperatures at the poles tend to be below freezing.
90 ... at the north and south poles.
Along warm water currents from the equator to the poles.
