Dinosaur Extinction Theories and Effects

The video explores the mystery of dinosaur extinction, focusing on two main theories: the asteroid impact and volcanic eruptions. The asteroid theory suggests a massive impact at the Chicxulub crater caused environmental changes, while the volcanic theory points to eruptions in India. Both could have blocked sunlight, leading to a mass extinction. Despite these events, some species survived, highlighting life's resilience.

What is the main mystery discussed in the video?

• The evolution of birds

How long ago did the dinosaurs go extinct?

• 65 million years ago

• 160 million years ago

• 200 million years ago

• 50 million years ago

What is the name of the crater formed by the asteroid impact?

• Asteroid Crater

• Yucatán Crater

• Chicxulub Crater

• Dino Crater

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

• Global cooling

• Increased sunlight

• Massive fires and earthquakes

• Rise in sea levels

What is the alternative theory to the asteroid impact?

• Tsunami waves

• Solar flares

• Volcanic eruptions

• Comet collision

Where did the significant volcanic eruptions occur?

• Mexico

• India

• Australia

• Africa

What common effect did both the asteroid and volcanic theories suggest?
