6 dni temu · Ocean currents are patterns of water movement that influence climate zones and weather patterns around the world. They are primarily driven by winds and by seawater density, although many other factors – including the shape and configuration of the ocean basin they flow through – influence them.
19 paź 2023 · Ocean currents flow like vast rivers, sweeping along predictable paths. Some ocean currents flow at the surface; others flow deep within water. Some currents flow for short distances; others cross entire ocean basins and even circle the globe.
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density. Ocean water moves in two directions: horizontally and vertically.
The currents, defined as persistent directed movements of seawater, aid in spreading the tidal bulges across the globe’s oceans. Simultaneously, waves, disturbances that traverse through a medium, transport the tidal energy across the ocean surface. Therefore, both currents and waves are crucial in molding the tides visible along our coastlines.
In this TED-Ed by Jennifer Verduin, directed by Cabong Studios, we learn how surface currents, deep ocean currents, wind, salt, gyres, the Coriolis Effect, and other powerful factors affect how water moves around the planet.
Winds and other forces cause ocean water to be constantly in motion. Large amounts of ocean water move around Earth in patterns called currents. Ocean currents may be warm or cold. Warm currents tend to bring warm weather and rain to nearby land. Cold currents tend to cause a dry climate.
