Ocean Currents

Differences in water temperature in the ocean create movement because–

• as water heats up, the atoms of water more faster.

• warm water is pulled more by gravity than cold water.

• warm and cold water mix and reach the same temperature.

• bodies of water at different temperatures have different densities.

One of the characteristics of ocean water that causes ocean currents is salinity. Differences in salinity can generate movement in the ocean because the amount of dissolved salt in ocean water correlates to–

• how quickly it evaporates.

• its ability to conduct electricity.

• the latitude where it is found.

• the density of the water.
