• an ocean layer where rapid change in temperature occurs

• an ocean layer where rapid change in salinity occurs

• an ocean layer where rapid change in density occurs

• an ocean layer where rapid change in turbidity occurs

Why does ice float?

• As water freezes, it expands and its density decreases.

• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.

• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.

• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
