Waves in Motion

the foamy surface of the ocean

The ocean is constantly in motion, and it's not just the waves that crash ashore. Wind moves the water at the surface and deep underwater currents, driven by temperature and salinity, move across ocean basins. From beyond the Earth's atmosphere the Moon and Sun pull at the ocean and as a result, on Earth, we experience tides. Even the Earth’s rotation affects ocean movement, causing moving water to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
