What is salinity a measure of?

• The amount of dissolved oxygen in the water

• The amount of dissolved salt in the water

• The temperature of the water

• The depth of the water

How does temperature affect the density of water?

• It does not affect the density.

• Water with colder temperatures is less dense.

• Water with higher temperatures is more dense.

• Water with colder temperatures is more dense.

What do convection currents in the ocean do?

• Move cold water towards the surface and warm water deep into the ocean.

• Move warm water towards the surface and cold water deep into the ocean.

• Keep warm water at the surface and cold water at the bottom without movement.

• Cause the ocean water to freeze.
