That's right, not all rocks are from Earth. Sure you can debate whether a meteorite is a rock, but you definitely find them all over the Earth. Some super big ones have created massive craters across the globe. Most scientists now believe that a super-massive meteorite hit the Earth and created an extinction event for the dinosaurs. There are also millions of tiny meteorites. They look just like rocks until you break them open. Meteorites are mainly made of iron and nickel. You will also find many smaller trace elements. The key thing to remember about meteorites is that they have much different percentages of elements than rocks on Earth. Many trace elements found on these space travelers are nearly impossible to find on Earth.
