A metallic shine on the surface of the rock, Small rounded pieces of stones on the surface (these are known as chondrules), A black or brown coating known as fusion crust (this is produced by the extreme heat of flying through the atmosphere), Small dents covering the surface of the rock (this is regmaglypt texture or thumbprints). Achondrites, on the other hand, do not contain chondrules and are thought to be fragments of larger asteroids that have been broken up by collisions.

A witness fall is when a meteorite falls in the sky as a result of credible observers observation. Thats because the process of creation of a volcanic rock includes extreme heat, which creates air bubbles while cooling down.
