Final answer:
The interaction between the atmosphere and the hydrosphere that causes most surface, ocean currents is the water cycle.
Step-by-step explanation:
The interaction between the atmosphere and the hydrosphere that causes most surface, ocean currents is the
water cycle. The water cycle is driven by the Sun's energy, which warms the oceans and other surface waters. This leads to evaporation of liquid surface water and sublimation of frozen water, moving large amounts of water into the atmosphere as water vapor. Over time, this water vapor condenses into clouds and eventually leads to precipitation, which returns water to Earth's surface and creates currents in the ocean.
