What would happen if the Earth was hit by a meteor?

This would have killed some plants, disrupting the food chain. Later calculations (especially by Jay Melosh at the University of Arizona) indicated that for the first few hours after the impact, rocky debris would have fallen back into the high atmosphere, creating a storm of glowing fireballs in the sky.

Now, scientists think they know where that object came from. According to new research, the impact was caused by a giant dark primitive asteroid from the outer reaches of the solar system’s main asteroid belt, situated between Mars and Jupiter.

What killed the dinosaurs that killed dinosaurs?

The asteroid impact led to the extinction of 75\% of life, including all non-avian dinosaurs.

What if the asteroid that killed the dinosaurs missed Earth?

In this scenario, today’s world might be full of reptiles and short on mammals — including people. But even if the asteroid hadn’t hit, dinosaurs and other Cretaceous life forms might have become extinct anyway. Some dinosaur species had started to dwindle long before the asteroid’s impact.

What happened after dinosaur extinction?

After the dinosaurs’ extinction, flowering plants dominated Earth, continuing a process that had started in the Cretaceous, and continue to do so today. ‘All of the non-bird dinosaurs died out, but dinosaurs survived as birds. Some types of bird did go extinct, but the lineages that led to modern birds survived.
