Meteors consist of rock or gravel grain and sometimes fall into the soil atmosphere, but it is unusual. Most often the grains are so small that they burn up before reaching the ground.
Stones from space found on earth are called meteorites. When a larger meteor hits the ground, a crater can be caused by the impact.
The most recent example of a collision occurred in Russia in 1908, when a fireball strong as the sun seemed over a sparsely populated area in Siberia.
