How impact craters form

How are craters formed? What can craters on the Moon tell us about earth? For centuries many have observed the large black markings on the Moon and wondered what they were but we now know that they’re large impact basins or crater that would have formed when a comet or Asteroid collides with a planet. It’s easy to assume that all craters are the same but they can vary wildly depending on the size, shape and the speed of the asteroid or comet that created it. The following 3 films explore how and why craters are formed, and what they can tell us about both the earth and the early solar system.
