This TED-Ed lesson featureshow ocean currents work. It starts with a story of how rubber ducks got swept away by ocean currents. Then, it gets into what influences ocean currents. For example, the wind, tides, water density, rotation, and even ocean floor topography influence currents in th...
The oceans of the world, however, are not homogeneous. Horizontal variations in temperature and salinity cause the horizontal pressure gradient to vary with depth. This is the baroclinic field of mass, which leads to currents that vary with depth. The horizontal pressure gradient in the ocean is...
major surface currents of the oceansMajor surface currents of the world's oceans. Subsurface currents also move vast amounts of water, but they are not known in such detail. Maps of the general circulation at the sea surface were originally constructed from a vast amount of data obtained from...
D. New Guinea is on the north of it. 3. Why is the water at the poles less salty? A.Little of it turns into steam. B.There is abundant rainfall there. C.The ocean currents are slow there. D.Melting snow adds water to the ocean. 4. We can infer from the passage that___. A...
The Pacific Northwest is one of the world"s best areas for beachcombing(海滩搜寻) because winds and currents join here, and as a result, there is a group of serious beachcombers in the area. Ebbesmeyer got to know a lot of them and asked for their help in collecting information about ...
If you've ever lost your hat or a pair of sunglasses in the ocean, then you know that the sea doesn't stay still. If you didn't retrieve the lost item immediately, it was likely well on its way to the other side of the world, carried away by ocean currents. ...

Ocean currents refer to the mass flow of water driven by winds, transferring heat, influencing weather and climate, distributing nutrients, and dispersing marine organisms in the oceans. They are a form of kinetic energy that plays a crucial role in the Earth's climate system and have the pote...
