The image below shows the characteristic surface currents of the ocean. Deep below the surface, there are currents that are controlled by water density, which depends on the temperature and salinity of the water. Sites away from the coast lack this temperature buffering and have extreme "continental" climates (like Wichita). When two continental plates diverge, rifts/valleys and volcanoes are formed.
