TED-Ed: How big is the ocean? - Scott Gass

The video explores the vastness and unity of the ocean, emphasizing its role as a single massive body of water covering 71% of Earth's surface. It holds 97% of Earth's water and 99% of the biosphere, making it crucial for life. The ocean's geological features include the mid-ocean ridge, the largest mountain range, and the Challenger Deep, the deepest canyon. Despite its enormity, human activities impact the ocean, with half the world's population living near coastlines. The video highlights the ocean's significance and the human responsibility to protect it.
