Asteroid Impact and Its Consequences

What was the estimated size of the asteroid that caused the extinction of the dinosaurs?

• 15 to 20 miles wide

• 6 to 9 miles wide

• 3 to 5 miles wide

• 10 to 12 miles wide

How did the Earth's climate 66 million years ago differ from today?

• It was cooler with less humidity

• It was colder with more oxygen

• It had similar temperatures and humidity

• It was hotter with extreme humidity

What was one of the long-term effects of the asteroid impact on the dinosaurs?

• Dinosaurs evolved into mammals

• Immediate extinction of all dinosaurs

• Gradual extinction over thousands of years

• Dinosaurs migrated to other planets

What role did mammals play after the extinction of the dinosaurs?

• They became the dominant species

• They went extinct as well

• They remained unchanged

• They became aquatic creatures

How might modern technology help us if a similar asteroid were to approach Earth today?

• It would make the asteroid change its course

• It would prevent the asteroid from entering the atmosphere

• It would help us detect the asteroid in advance

• It would allow us to destroy the asteroid

What immediate effects would a modern-day asteroid impact have on Earth?

• It would cause minor earthquakes

• It would create a new ocean

• It would cause massive earthquakes and tsunamis

• It would have no significant impact

What is an 'impact winter'?

• A period of volcanic activity

• A period of increased rainfall

• A period of extreme heat following an impact

• A period of extreme cold due to blocked sunlight

What challenges would humans face in surviving after a catastrophic asteroid impact?

• Lack of sunlight and food

• Improved climate conditions

• Increased oxygen levels

• Abundant resources

What is the likelihood of new life forms emerging after an asteroid impact?

• Likely, as new conditions could foster evolution

• Impossible

• Certain, as life always finds a way

• Very unlikely

What might be a potential strategy for human survival after an asteroid impact?

• Building floating cities

• Living underground

• Colonizing other planets

• Living underwater
