The researchers increased either winds, saltiness, or surface temperatures, while holding all other variables steady. The best explanation for the lower humidity is that, Warm air rises at the equator, cools, and sinks at 30* latitude, Open oceans produce the largest share of Earth's biomass because the net primary productivity (NPP) of the oceans is, Low, but the large expanse of the oceans supports enormous numbers of producers such as phytoplankton, Surface oceanic circulation results most directly in the, Distribution of heat from tropical to temperate and polar regions. Ocean currents flow like vast rivers, sweeping along predictable paths. This cold, salty water near the poles (primarily in the North Atlantic and near Antarctica) sinks and spreads along the bottom and eventually rises back towards the surface of the ocean. c. adaptive radiation Driven in large part by wind, each of them moves as much water as all the worlds rivers combined.

Hover over or click on the icons to learn more about these human causes of change and how they influence, or are influenced by, ocean circulation. Currents can be broken down into two forms of circulation.
