Oceanography Test Review

The thermocline is

• 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

A SINGLE water molecule is held together by

• 1 hydrogen bond

• 2 hydrogen bonds

• 1 covalent bond

• 2 covalent bonds

Which of the following would INCREASE salinity in a location?

• Runoff from land

• Ice melting

• Evaporation

• Heavy rainfall

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.

The water of the Amazon River often looks brown, due to run-off of sediment upstream. This water has a _____________________.

• b. High turbidity

• a. Low salinity

• c. High temperature

• d. Low pH

_____ Downwelling delivers water from the surface to the deep that is rich in

• fish

• nutrients

• oxygen

• kittens

The Ocean Conveyor Belt is also called thermohaline circulation because it is driven by

• winds

• Coriolis Effect

• differences in temperature and salinity

• El Nino

Which of the following is not true of the Gulf Stream?

• it is strongest in the winter

• it has a warming effect on the climate of western Europe

• it influenced the downwelling in the North Atlantic where thermohaline circulation begins

• if it weakened or stopped, climate would be dramatically affected
