Multiple Choice

The table below lists some information about the minerals graphite and diamond.

Some properties of diamond are different from those of graphite because diamond

• has a different arrangement of atoms

• forms larger crystals

• has a different composition

• is older in geologic age

Multiple Choice

The diagrams show the crystal shapes of two minerals.

Quartz and halite have different crystal shapes primarily because

• light reflects from crystal surfaces

• energy is released during crystallization

• of impurities that produce surface variations

• of the internal arrangement of the atoms
