• A region with no temperature change

• A region with increased salinity

What is the primary function of the AMOC?

• To regulate ocean salinity

• To transport heat globally

• To decrease ocean acidity

• To increase atmospheric pressure

Who coined the term 'cold blob'?

What drives the Gulf Stream?

• Tidal forces

• Volcanic activity

• Surface winds and Earth's rotation

• Thermohaline circulation

What could happen if the AMOC collapses?

• Increased global temperatures

• Decrease in sea levels

• Significant cooling in the Northern Hemisphere

• Stabilization of weather patterns

How might the AMOC's weakening affect the North Atlantic?

• Decrease in marine biodiversity

• Increase in sea level rise
