Meteorites
Shapes and Sizes
Meteorites come in all sizes and shapes.
Meteorites come in many different shapes such as square, weird, rounded and some you never would guess.Meteorites come slamming into the atmosphere and break up into nearly any shape and into pieces from dust to the largest weighing many tons. Meteorites have several distinguishing characteristics that make them different from terrestrial (Earth) rocks. Meteorites which have fallen recently may have a black "ash-like" crust on their surface. When a meteorite falls through the Earth's atmosphere a very thin layer on the outer surface melts. This thin crust is called a fusion crust. Most meteorites contain at least some iron metal (actually an alloy of iron and nickel). You can see the metal shining on a broken surface. Most meteorites contain some iron-nickel metal and attract a magnet easily. A magnet will stick to the meteorite if it contains much metal.
Fusion Crust
This is caused when the surface melts as it falls from the sky.
Iron Meteorite
Iron meteorites have a dense, silvery appearing interior with no holes or crystals.
Meteorites are magnetic!
You can use an ordinary refrigerator magnet to test this property.
