WebConvection penetrates to a level where the density of the sinking water matches that of the surrounding water. It then spreads slowly into the rest of the ocean. Other water must replace the surface water that sinks. This sets up the thermohaline circulation. WebMar 31, 2024 · The ocean absorbs heat from the Sun and ocean currents move that warm water all around the planet. Ocean currents are like highways that carry water around the world. Heat (along with salt) is a major source of power for ocean currents. Cold water near the North and South Poles sinks deeper into the ocean. Water near the equator is warmed …
