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.
Concentration gradients can be found in all systems on earth and throughout the universe. They drive much of the movement of ions, temperature, and other materials.
