Question

c. how big was the asteroid/comet that caused the extinction of the dinosaurs?
type your response here:

Explanation:

Scientists estimate that the asteroid/comet that caused the dinosaurs' extinction was approximately 10 - 15 kilometers in diameter. This size is inferred from the geological evidence such as the Chicxulub crater in Mexico, which is about 180 kilometers in diameter. The impact of an object of this size would have released an enormous amount of energy, causing global environmental changes like wildfires, a "nuclear winter" - like effect (blocking sunlight), and acid rain, which led to the mass extinction of dinosaurs and many other species.

Answer:

The asteroid/comet was approximately 10 - 15 kilometers in diameter.
