At the poles the oceans get colder.  Freshwater is removed from the ocean as icebergs form.  This leaves behind the salt.   This process _______ the density of the ocean water.  

• increases

• decreases

How do ocean currents affect the temperature of water?

• They cool down the water uniformly

• They heat up the water by the Sun's radiation

• They distribute water that has been unevenly heated by the Sun's radiation

• They have no effect on the temperature of water
