Asteroid Impact Effects and Consequences

The video explores the catastrophic impact of a massive asteroid 66 million years ago, which led to the extinction of the dinosaurs. It discusses the mechanics of such an impact, including the ejection of material into the atmosphere and the global effects that would ensue. The video also examines the potential increase in carbon dioxide levels and the greenhouse effect, comparing it to modern fossil fuel emissions. Finally, it considers the survival challenges and long-term scenarios humanity might face if a similar event occurred today.

What major event occurred 66 million years ago that had a significant impact on Earth?

• A major earthquake

• A global ice age

• A large asteroid impact

• A massive volcanic eruption

What happens to the Earth's crust during an asteroid impact?

• It melts and forms new land

• It remains unaffected

• It is thrown into the atmosphere

• It sinks into the ocean

How would a modern-day asteroid impact affect the world?

• It would only affect the oceans

• It would have no significant effect
