When you think of the moon, you think of craters. You can have a rock that is from the moon or Mars or you can anasteroid and these can have all sorts of different names. Most typically the ones that end up hitting planets they were calling chondrites.You get iron meteors that hit planets. When they impact they can come in at all sorts of different angles. The angle of impacts affects what direction the ejecta travels. This is the cloud of material that gets thrown out of the ground and spewed in different directions. There are a lot of really complicated processes that go into this. You hit downward and material gets flung upwards as the energy is being released. It just ends upleading to this nice happy little perfectly round crater. You can get craters that end up with multiple rings of material around them. You end up with craters that have neat layers layered through them with all sorts of different morphologies depending on where you hit. Anyone can find a meteor. They are all over the planet. They are easiest to findin deserts and in Antarctica. But you could find one in your back yard if you’re lucky.
