Answer:
The correct answer is wind.
Step-by-step explanation:
Wind is a major factor that causes surface ocean currents in the open ocean that drags the surface of water as it moves. In this case the wind is responsible in pulling surface water to create current in form of waves and tides. Enabling the control of climate since heat is able to move from the equator to the poles using ocean currents. The currents further play a significant role in sea life by carrying nutrients and food to organisms living deep within the sea.
