    • Exposed to the elements

      Some meteorites, such as Dalgety Downs, sit outside for thousands of years before they're discovered. Rain, wind, heating and cooling can cause weathering of the surface  —rust and cracks that eventually break a meteorite to pieces. Weathering begins as soon as moisture in the air contacts the meteorite's surface. Even slight weathering begins to destroy clues to the rock's original composition.
