Question

Which of the following statements about thermohaline circulation is true?

A_ In thermohaline circulation, the upwelling of warm waters in the tropics circulates denser water toward the poles.

B-Thermohaline circulation brings surface waters from the poles toward the equator, where the water then sinks and returns toward the poles.

C-Thermohaline circulation is created by the expansion of ocean water as it cools and becomes less dense

D- In thermohaline circulation, surface waters become more dense as evaporation and cooling occur.

Which of the following statements about the Gulf Stream is true?

A-The Gulf Stream is a fastmoving current of air that impacts weather and thermohaline circulation in the Northern Hemisphere.

B-The Gulf Stream carries warm water northward from Florida toward the northeastern U.S. and Europe.

C-The Gulf Stream is a small river that carries runoff from the midwestern U.S. into the Gulf of Mexico.

D-The Gulf Stream circulates warm ocean currents in the Gulf of Mexico.

answes :1) In thermohaline circulation, surface waters become more dense as evaporation and cooling occur.

evaporation nad decrese in temperatures leads to the increase on salinity/denisty of waters and hence the water will sinks to the bottom

2) The Gulf Stream carries warm water northward from Florida toward the northeastern U.S. and Europe

gulf stream is a fast moving warm current of ocean water that originates in gulf of mexico and transport warm waters to the poles
