A Correct answer
Explanation

The five major mass extinctions are the Ordovician-Silurian extinction, the Devonian extinction, the Permian-Triassic extinction, the Triassic-Jurassic extinction, and the Cretaceous-Paleogene extinction.

Multiple choice

The Permian-Triassic extinction was the:

  1. Largest mass extinction in Earth's history

  2. Second largest mass extinction in Earth's history

  3. Third largest mass extinction in Earth's history

  4. Fourth largest mass extinction in Earth's history
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Permian-Triassic extinction was the largest mass extinction in Earth's history, with an estimated 96% of all marine species and 70% of all terrestrial vertebrate species becoming extinct.

Multiple choice

The Cretaceous-Paleogene extinction was caused by:

  1. An asteroid impact

  2. A volcanic eruption

  3. A combination of an asteroid impact and a volcanic eruption

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Cretaceous-Paleogene extinction was caused by a combination of an asteroid impact and a volcanic eruption, which led to a global climate change and the extinction of many species, including the dinosaurs.

Multiple choice

The recovery from mass extinctions is typically:

  1. Rapid

  2. Slow

  3. Variable

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The recovery from mass extinctions is typically variable, with some ecosystems recovering more quickly than others. The rate of recovery depends on a number of factors, including the severity of the extinction, the availability of resources, and the presence of resilient species.

Multiple choice

Which of the following is an example of a vicariance event?

  1. The formation of the Isthmus of Panama

  2. The breakup of the supercontinent Pangea

  3. The rise of the Rocky Mountains

  4. The retreat of the glaciers during the last ice age
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vicariance is the process by which a population is divided into two or more geographically isolated populations. The breakup of Pangea is an example of a vicariance event because it resulted in the isolation of many different groups of organisms.
