All of the factors below play a role in creating ocean currents. Which factor has the greatest influence on weather patterns?

earth's rotation

heat capacity

salinity

bottom topography

I think the correct answer from the choices listed above is the second option. Of all the factors, it is heat capacity that has the greatest influence on weather patterns. Ocean currents move warm and cold bodies of water around. Water has a specific heat capacity thousands of times that of air, and as a result are able to chill or heat the air over them, as well, as are the source of vapor that becomes clouds and precipitation.
