What If the Asteroid Never Killed the Dinosaurs?

What was the significant event that changed the course of life on Earth 66 million years ago?

• A massive volcanic eruption

• A sudden ice age

• A global flood

• A giant asteroid impact

What was one of the immediate effects of the asteroid impact on Earth?

• Increase in oxygen levels

• Rise in sea levels

• Formation of new continents

• Blocking out of the sun

What is one theory about the state of dinosaurs before the asteroid impact?

• They were thriving and increasing in numbers

• They were already in decline

• They had just begun to evolve

• They were migrating to new continents

If the asteroid had missed Earth, what is one possible outcome for the dinosaurs?

• They would have become extinct due to a new predator

• They would have continued to evolve and dominate

• They would have migrated to other planets

• They would have become smaller in size

What is one reason why mammals might not have risen if the asteroid had not hit Earth?

• The climate was too harsh for mammals

• Mammals were not adaptable

• Dinosaurs would have continued to dominate the food chain

• Mammals were too large to survive

What is a potential evolutionary trait that some dinosaurs might have developed over millions of years?

• Photosynthesis

• Underwater breathing

• Human-like intelligence

• Ability to fly

What is one argument against the idea that dinosaurs would have evolved to look like humans?

• Dinosaurs were cold-blooded

• Dinosaurs were too large

• Human-like evolution is not the only possible outcome

• Dinosaurs were not intelligent enough

What is one alternative scenario that could have led to dinosaur extinction besides the asteroid?

• A solar flare

• A massive earthquake

• A new ice age

• Global warming and climate change

What major geological event occurred during the Mesozoic Era?

• Creation of the Grand Canyon

• Break-up of Pangaea

• Formation of the Great Barrier Reef

• Formation of the Himalayas

What was the impact of the asteroid on the evolution of mammals?

• It had no impact

• It delayed their evolution

• It accelerated their evolution
