Dinosaurs and Their Extinction

The video explores why dinosaurs went extinct, highlighting that scientists are unsure but suggest a massive asteroid and volcanic eruptions as possible causes. These events could have blocked sunlight, leading to the extinction of many species. However, some dinosaurs survived and evolved into birds, linking modern birds to their dinosaur ancestors.

What is the main reason scientists are unsure about the exact cause of dinosaur extinction?

• Dinosaurs are still alive today.

• There are multiple possible causes for the extinction.

• The extinction happened too recently to study.

• There is no evidence of dinosaurs ever existing.

What major event is believed to have contributed to the extinction of dinosaurs?

• A global flood

• A solar eclipse

• A large asteroid impact

• A massive earthquake

How did volcanic eruptions potentially affect dinosaur life?

• By increasing oxygen levels

• By providing more food

• By blocking sunlight with dust

• By creating new habitats

What happened to the dinosaurs that survived the extinction event?

• They moved to another planet.

• They became extinct later.

• They evolved into mammals.

• They evolved into birds.

What modern-day animals are considered descendants of dinosaurs?

• Mammals

• Amphibians

• Reptiles

• Birds
