Angles and Edges

If a rock has angles and edges but no fusion crust, then it is not a meteorite

For small meteoroids, 90% of the mass is lost to ablation as they come through the Earth’s atmosphere. Edges, “corners,” rough surfaces, and any other protuberances are the first parts to ablate away. Put an ice cube in water and wait for 90% to melt. The “cube” that is left will have no edges or points. It is like that with meteorites.
