How Big Is the Ocean? A TED-Ed Animated Lecture

In this TED-Ed animated lecture, educator Scott Gass discusses the mind-boggling scale of the ocean, which encompasses 99% of the earth’s biosphere and is the site of the world’s largest mountain range. The animation was created by Sandro Katamashvili.

While the Earth’s oceans are known as five separate entities, there is really only one ocean. So, how big is it? As of 2013, it takes up 71% of the Earth, houses 99% of the biosphere, and contains some of Earth’s grandest geological features. Scott Gass reminds us of the influence humans have on the ocean and the influence it has on us.
