Ocean Salinity

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.

Which of these characteristics will produce the least dense water?

• High salinity, high temperature

• High salinity, low temperature

• Low salinity, high temperature

• Low salinity, low temperature

What is the driving force of the deep water ocean conveyor belt?

• Winds push the deep water into the Pacific and Indian oceans.

• Gravity from the moon pulls the water towards the equator.

• The spinning of Earth makes the deep water current run in circular paths.

• Very cold temperatures at the poles create very cold, salty water that pushes the deep water current.
