- The reason why dinosaurs were wiped off earth was because at the time that the asteroid hit earth, the dinosaur ecosystems had already weakened due to loss of biodiversity.
- Result of the violent collision that occurred 66m yrs ago in the present Mexico:
- Tsunamis across oceans.
- Powerful earthquakes.
- Release of enough amount of heat to trigger huge fires.

- Sun’s warmth was blocked.
- Earth cooled temporarily by about 10°C.
