What is the principal cause of the Late Devonian Extinction:

• Ice age and falling sea levels

• Lack of oxygen in the oceans (possibly caused by plant overgrowth and climate change)

• Massive volcanic eruptions, global warming, and toxic gases

• Volcanic eruptions and sudden climate change.

What is the principal cause of the : Ordovician-Silurian Extinction:

• Ice age and falling sea levels

• Lack of oxygen in the oceans (possibly caused by plant overgrowth and climate change)

• Massive volcanic eruptions, global warming, and toxic gases

• Volcanic eruptions and sudden climate change.

What is the principal cause of the: Triassic-Jurassic Extinction

• Ice age and falling sea levels

• Lack of oxygen in the oceans (possibly caused by plant overgrowth and climate change)

• A meteorite struck Earth, causing fires and blocking sunlight

• Volcanic eruptions and sudden climate change.

What is the principal cause of the Cretaceous- Paleogene Extinction

• Ice age and falling sea levels

• Lack of oxygen in the oceans (possibly caused by plant overgrowth and climate change)

• A meteorite struck Earth, causing fires and blocking sunlight

• Volcanic eruptions and sudden climate change.
