Sites away from the coast lack this temperature buffering and have extreme "continental" climates (like Wichita). 0 & 1 & 2 Winds, water density, and tides all drive ocean currents. Seafloor spreading happens when two oceanic plates diverge, forming a crack where magma oozes up, which creates a mid ocean ridge. Ocean water is constantly moving, and not only in the form of waves and tides. Sites on islands or coasts benefit from the moderating effect of the ocean and have "maritime" climates (like San Francisco).
