Underwater Volcano

The video explores the causes of ocean currents, focusing on volcanic activity. An experiment is conducted to simulate an underwater volcano, demonstrating how temperature differences create convection currents. The process involves using hot and cold water, food coloring, and a glass tank. The video explains how convection occurs due to density differences, with hot fluids rising and cold fluids sinking. This principle is also applied to air currents, showing how thermals allow hang gliders to fly.
