A TED-Ed Animation Explaining Some of the Physics Behind How Oceans Move

Our Earth, covered by 71% water, moving in one enormous current around the planet.

In this TED-Ed animated lecture, educator Sasha Wright explains the physics behind our oceans’ concentration gradient, and how that causes the contents of any given ocean to fight over space.

The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers — the concentration gradient — and illustrates how our oceans are continually engaging in a universal struggle for space.
