Exploring Ocean Facts and Concepts

This video from Mumu Math and Science explores the ocean biome, which covers 70% of Earth's surface. It discusses the five major oceans—Pacific, Atlantic, Indian, Southern, and Arctic—and their subdivisions into seas. The ocean is rich in life, from large whales to microscopic plankton, and features like coral reefs and the mid-ocean ridge. The ocean influences weather and has been a vital trade route. Despite its vastness, only 5% has been explored. The video encourages viewers to appreciate the ocean's diversity and significance.
