How do you know asteroids have hit the earth?

Answer 1

The evidence that asteroids have collided with earth before, depends on the surface. The way you can find this if there is unusual shapes in the ground( e.g. really deep ditch, that is too big for a human too dig).

Answer 2

Scientists study impact craters, which are formed when asteroids hit the Earth. They analyze the size, shape, and composition of these craters to determine if they were caused by asteroid impacts. Additionally, they look for evidence like shocked quartz and impact melt rocks that are typically found around impact sites.

Answer 3

As with any massive collision there are chunks of debris. Many times asteroids from the asteroid belt that collide are sent hurling out of the belt. This is where a large portion of meteors an near earth objects come from.

Answer 4

Craters are a significant sign of collisions with asteroids therefore yes asteroids collide with Earth
