Impact Craters
Impact craters are circular depressions on the surface of a planet, moon, or other solid body in space that are formed when a smaller object, such as a meteoroid or asteroid, collides with the surface at high velocity. The impact of the smaller object creates a shock wave that travels through the solid body, causing the material to be compressed and heated, and then rebound and eject from the impact site. The resulting crater can range in size from a few meters to hundreds of kilometers in diameter, depending on the size and velocity of the impacting object, as well as the properties of the target material. Impact craters are important features for understanding the geological history of a planet or moon, as they can provide information about the age and composition of the surface material, as well as the frequency and intensity of impact events over time.
