What is the primary cause of the Younger Dryas, according to the megaflood hypothesis?

• A massive volcanic eruption

• An asteroid impact in the Atlantic Ocean

• The sudden draining of a giant freshwater lake into the ocean

• A shift in Earth's orbital path around the sun

How did the influx of freshwater from Lake Agassiz affect the Atlantic Meridional Overturning Circulation (AMOC)?

• It made the AMOC stronger and faster

• It diluted the North Atlantic water, causing the AMOC to slow down or stop

• It caused the AMOC to reverse direction

• It had no significant effect on the AMOC

Which of the following was an impact of the Younger Dryas period?

• Expansion of forests and grasslands

• The disappearance of the Clovis culture
