Which of the following describes the event and feedbacks believed to have caused the biggest mass extinction seen in the geologic record? (This mass extinction was during the Permian period and is often called “The Great Dying.”)

• When a supercontinent broke apart, chemical weathering caused CO2 levels in the atmosphere to decrease, resulting in extreme global cooling.

• Huge volcanic rifting events release lava and large amounts of CO2 to the atmosphere. This caused runaway warming and ocean acidification.

• The rise of mammals. Packs of small mammals competed for food and preyed on eggs.

• A 10-kilometer wide asteroid caused a period of extreme cold that was followed by extreme warmth.
