1. The diagrams below represent the crystal shape and type of cleavage of
two different minerals. The crystal shape and type of cleavage of these
two minerals are determined mainly by the minerals
Crystal shape: cubic
Cleavage: three directions
- all at right angles
O A) color and type of luster
Crystal shape: rhombohec
Cleavage: three directions
- not at right angles
B) streak and hardness
OC) composition and atomic arrangement
OD) density and magnetism
