Hematite A mineral that is often found in meteorites. It does not attract a magnet. When it is rubbed against an object harder than itself, it leaves a reddish-brown stain. Hematite is also sometimes called bloodstone . Igneous A type of rock that is formed when magma cools.
Igneous rocks can be either of volcanic or plutonic origin.
Some object, like a particle or crystal, that is embedded within another object. An analogy would be that of a chocolate chip in a chocolate chip cookie. Kamacite A mineral that is an alloy of nickel-iron. The bright streak of light that appears in the sky as a result of friction between a meteoroid and the air molecules in our atmosphere. Entering the atmosphere at speeds between 10 and 70 kilometers per second, the friction-generated heat is hot enough to melt the surface layer of the object and ionize the air.
