Step-by-Step Timeline of the Asteroid That Killed the Dinosaurs

The video explores the catastrophic asteroid impact that led to the extinction of dinosaurs. It details the immediate effects, such as shockwaves and molten debris, and the long-term environmental consequences, including mass extinction and climate changes. The video also discusses scientific theories and debates surrounding the event.

What was the initial reaction to the glowing star in the sky?

• It was ignored as a routine shooting star.

• It was immediately identified as an asteroid.

• It was considered a sign of good luck.

• It was thought to be a new planet.

What was the immediate effect of the asteroid's impact on Earth's atmosphere?

• It created a rainbow.

• It made the ocean freeze.

• It increased the ocean's temperature.

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

• Plants grew larger than before.

• Plants became more colorful.

• Plants died due to lack of sunlight.

• Plants started producing more oxygen.

What evidence supports the asteroid impact theory for the mass extinction?

• Presence of iridium in rock layers.
