The Ocean: A Driving Force for Weather and Climate

Learn how the ocean relates to weather and climate in this video from NASA. Uneven heating from the Sun drives ocean and atmospheric circulation. Animations and satellite data show how ocean currents and eddies distribute energy and nutrients around the world. Heat exchanges between the ocean and th

The Sun's Energy

In this video from NOVA’s Sun Lab, explore nuclear fusion and the balance of energy in the Sun. Intense heat and pressure in the Sun’s core cause protons to fuse together to form helium atoms, a process that releases large amounts of energy. This nuclear reaction—the same process that takes place in
