Exploring Earth's Ocean Zones and Salinity

Miacademy & MiaPrep Learning Channel

This comprehensive earth science video takes students on a deep dive into the mysteries and mechanics of Earth's oceans. Starting with the surprising fact that we know more about the surface of Mars than our own ocean floor, the lesson breaks down complex oceanographic concepts into three main sections: the origins of ocean salinity, the five distinct zones of the ocean based on depth and light penetration, and the critical role oceans play in regulating the global climate and providing oxygen.
