Which mineral can be found in all samples of rhyolite and andesite?

• pyroxene

• quartz

• biotite

• potassium feldspar

The three statements below are observations of the same rock sample:

• The rock has intergrown crystals from 2 to 3 millimeters in diameter.

• The minerals in the rock are gray feldspar, green olivine, green pyroxene, and black amphibole.

• There are no visible gas pockets in the rock.

This rock sample is most likely

• sandstone

• gabbro

• granite

• phyllite

Which two properties are most useful in distinguishing between galena and halite?

• cleavage and color

• luster and color

• hardness and streak

• streak and cleavage

What is the approximate density of a mineral with a mass of 262.2 grams that displaces 46 cubic centimeters of water?

• 1.8 g/cm³

• 5.7 g/cm³

• 6.1 g/cm³

• 12.2 g/cm3

Which of the following elements is not found in Plagioclase Feldspar?

• Na

• Al

• Si

• Pb

The minerals talc, muscovite mica, quartz, and olivine are similar because they

• have the same hardness

• are the same color

• contain silicon and oxygen

• break along cleavage planes

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

Which process most likely formed a layer of the sedimentary rock, gypsum?

• precipitation from seawater

• solidification of magma

• folding of clay-sized particles

• melting of sand-sized particles
