La circulación termohalina

The video explains the great ocean conveyor belt, a global current that regulates climate by distributing heat. It is driven by the sinking of cold, salty water in the Nordic oceans, which pulls in warmer tropical waters. This cycle takes about 1000 years to complete. The Gulf Stream, part of this system, is crucial for Western Europe's climate. The process is continuous, with water traveling from the Arctic to the Indian and Pacific Oceans and back.

What is the primary function of the great ocean conveyor belt?

• To generate ocean waves

• To distribute heat around the planet

• To create ocean tides

• To produce marine life

What happens to ocean water when it freezes in the Nordic regions?

• It becomes less salty

• It expels salt and becomes denser

• It evaporates

• It turns into freshwater

How does the sinking of cold, salty water affect the conveyor belt?

• It speeds up the conveyor belt

• It stops the conveyor belt

• It draws in warmer tropical waters

• It causes the water to evaporate

Which ocean current is crucial for warming Western Europe?

• The Gulf Stream

• The Antarctic Flow

• The Indian Ocean Current

• The Pacific Stream

How long does it take for the surface current to travel from the Arctic to the American continent?

• 500 years

• 100 years

• 50 years

• 10 years
