Summary:"Meteoroids are pieces of rock that once were part of another celestial body. These pieces of rock can be of microscopic size to several meters across. When the rock enters the earth's atmosphere, it is referred to as a meteor or """"""""shooting star."""""""" If the rock strikes the surface of the planet, we change the terminology again and refer to the object as a """"""""meteorite."""""""" Most meteors burn up in the atmosphere, and those that impact our planet are usually extremely small. Few meteorites are ever found and therefore are extremely rare. Only thirteen confirmed meteorite falls or finds have been documented in the state of Indiana. For more information related to Indiana meteorites, refer to Poster 11 published by the Indiana Geological Survey. Only a small number of meteorites that strike the earth's surface actually create a significant impact crater. These impacts typically result in circular-shaped craters. Impacts at extremely low angles create elongated craters. This lesson is designed to examine how the volume, mass, and speed of meteorite impact will affect the dimensions of the resulting crater produced on the earth's surface."
