PAST SIMPLE TENSE

A big meteorite crashed into Earth, changing the climatic conditions so dramatically that dinosaurs could not survive.

Dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.

A huge rock from outer space (called an asteroid) smashed into the Earth.

It crash-landed near Mexico. It shook the ground. It made big waves in the sea

All the above.
