Multiple Choice

When identifying minerals, how do color and streak differ?

• Color describes the mineral's outer appearance. Streak is the color of the powder.

• Streak describes the mineral's outer appearance. Color is the pigment of the powder.

Multiple Choice

How does sedimentary rock form?

• when hot, molten rock crystallizes and solidifies.
