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 may have triggered an ice age and increased biodiversity. It also discusses the challenges of future Mars colonization, focusing on food independence and sustainable living. Researchers suggest that asteroid dust caused global cooling, transforming ecosystems and leading to a mass extinction. For Mars, the focus is on developing a food-independent society using methods like hydroponics and insect farming, highlighting the dependency on Earth for initial supplies.

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

• A volcanic eruption

• A massive asteroid breakup

• A shift in ocean currents

• A change in Earth's magnetic field

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

• A decrease in atmospheric oxygen

• A significant increase in interplanetary dust

• A rise in sea levels

• 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 varied climates across different regions

What marked the end of the Ordovician period?

• The beginning of the Jurassic period

• The first recorded global extinction

• The formation of a new supercontinent

• The emergence of mammals

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

• Finding a breathable atmosphere

• Creating artificial gravity

• Establishing a food-independent society

• Building underwater habitats

Why is farm-raised meat unlikely to be a staple on Mars?

• Inability to transport livestock

• Lack of water resources

• High resource and space requirements

• Lack of sunlight

What alternative protein source is suggested for Mars colonization?

• Insect farming

• Lab-grown meat

• Fish farming

• Soy-based products
