How many places on Earth have evidence of asteroid impacts

There are about 160 places on Earth that display evidence of asteroid impacts. Depending on the size of an asteroid, it can have significant effects on the planet. If an asteroid strikes the ocean, it can create huge destructive tsunamis or tidal waves. If an asteroid strikes land, it can create a huge crater, cause earthquakes, and propel debris into the atmosphere, creating major climatic changes.

Meteor Crater near Flagstaff, Arizona, was the first definitive site to provide physical evidence that meteors have crashed into the Earth in the past.
