my school told us to do "events that changed the world" this time, so i made this
the extinction happened in the end of the cretaceous era. days before it impacted, it looked like a big, bright star that would appear at day and night. this asteroid caused volcanoes, massive earthquakes, massive fires, and tsunamis. after the asteroid impaced, fires dominated forests worldwide and there were more, smaller asteroids. dinosaurs survived by going into caves that got covered up by debris. after this, the world's atmosphere was covered with ash, preventing sunlight, which prevented plants, which prevented dinosaurs.
