Fulgurite (named from the Latin fulgur for lightning) occurs when lightning strikes soil, melting the minerals in the soil into a tube-shaped cast of the shape of the lightning bolt. It is sometimes referred to as "fossilized lightning" because of this.
Meteorites are chunks of rock from space that fall to the Earth. Meteorites come from Meteors. Typically meteors burn up in the Earth's atmosphere (causing shooting stars) however, sometimes meteors don't fully disintegrate during this process. Meteorites are these un-burnt portions of meteor. Every day, 50 tons of space debris fall onto the surface of Earth, however, 99% of the debris is the size of dust particles. These particles of space debris are called Micrometeorites. The largest meteorite discovered on the Earth's surface is the Hoba meteorite. The Hoba is 119,000 lbs and still sits in its original landing place in Namibia, it's too heavy to be moved!
