Asked by delilah:)

An unknown mineral specimen is not scratched by a penny and does not exhibit cleavage. The mineral is most likely to be:


obsidian

halite

fluorite

I think it's either obsidian or fluorite!
Answered by DrBob222
Fluorite has cleavage.
Halite has cleavage.
Obsidian is about 5.5 or so on the Mohs scale while a penny is about 3; therefore, a penny will not scratch obsidian.
