How Big is the Ocean?

How big is the ocean? It's really big! You know it covers more of the Earth's surface than land does, but the exact proportions may surprise you. Considering how big the ocean is, we don't pay as much attention to its vastness, because we don't live there. But most of Earth's living things do. Scott Glass makes it all real in the TED-Ed video.
