Chapter 2 Minerals Test

Minerals are grouped according to their

• structure
• composition
• density
• mass

To identify a mineral, scientists may scratch a mineral against a surface. The color of the powder left behind is the mineral's

• element
• streak
• luster
• fluorescence

All minerals are

• cubic
• hexagonal

• mining the mineral

Which of the following is one of the way to tell which of the two minerals is harder?

• the harder mineral will mark a penny
• the harder mineral will attract a magnet
• the harder mineral will scratch the softer mineral
• the harder mineral cannot be scratched by steel

The best way to tell a pyrite sample from a gold sample of similar size is to compare their

• lusters
• colors
• densities
• bonds

An ore contains enough of a mineral that it

• has the same properties of the mineral
• has the opposite properties of the mineral
• can be mined easily
• can be mined for profit

If a mineral has perfect cleavage, it

• breaks easily
• scratches easily
• scratches smooth surfaces
• breaks along smooth surfaces
