The movement of the CO2 from the surface layer to the middle and deep layers of the ocean occurs through cooling and sinking of water at high latitudes and biological activity in the surface waters.
a. True b. False

Ocean and atmospheric circulation redistributes the heat around the planet, however more heat is transported in the oceans than in the atmosphere.
a. True b. False

Western intensification, is a result of the increase in the Coriolis force with latitude.
a. True b. False

The polar structure of the water molecule (H2O) permits weak magnetic bonds to be formed between individual water molecules when in the liquid state. These weak magnetic bonds are referred to as hydrogen bonds.
a. True b. False

Most of the excess heat gained in the low latitudes is redistributed to higher latitudes through convection.
a. True b. False

Geostrophic flow occurs when the Coriolis deflection is balanced by an opposite pressure gradient force.
a. True b. False
