Question

Pick four ways that the minerals found in rocks can be classified.
A.
weight

B.
color

C.
luster

D.
streak

E.
shape

F.
hardness

Answer 1

B, C, D, F — color, luster, streak, and hardness.

(Weight is not a standard diagnostic property—specific gravity is used instead—and shape/ crystal habit can help but is less commonly one of the primary four tests.)
