Did This Ancient Asteroid Cause an Ice Age? - SciShow News

The video explores the impact of asteroids on Earth's history, particularly during the Ordovician period, when an asteroid breakup led to a significant increase in biodiversity and a global cooling event. It also discusses the challenges of future Mars colonization, focusing on food independence and sustainable living on the red planet.

What significant event is suggested to have increased biodiversity during the Ordovician period?

• A massive asteroid breakup

• A volcanic eruption

• A shift in ocean currents

• A supercontinent formation

What was the primary effect of the asteroid breakup on Earth's climate?

• A significant increase in interplanetary dust

• A rise in sea levels

• A decrease in atmospheric oxygen

• Increased volcanic activity

How did the Ordovician ice age affect Earth's ecosystems?

• It caused widespread desertification

• It led to a uniform warm climate

• It increased volcanic eruptions

• It resulted in diverse climate zones

What marked the end of the Ordovician period?

• The formation of a new supercontinent

• The first recorded global extinction

• The rise of dinosaurs

• The beginning of a new ice age

What is a major challenge for establishing a human settlement on Mars?

• Establishing a breathable atmosphere

• Building large cities

• Providing a sustainable food supply

• Lack of water resources

What alternative protein source is suggested for Mars colonization?

• Lab-grown meat

• Fish farming

• Insect farming
