Geology Chapter 3 - Minerals

What is the classic geological definition of a mineral?

• Naturally occurring, inorganic, solid at room temperature, regular crystal structure, defined chemical composition

• Naturally occurring, organic, solid at room temperature, regular crystal structure, defined chemical composition

• Naturally occurring, organic, liquid at room temperature, irregular crystal structure, defined chemical composition

• Artificially created, inorganic, liquid at room temperature, irregular crystal structure, undefined chemical composition

Which process does NOT increase mineral precipitation?

• Changing pressure

• Evaporating water

• Cooling a fluid

• Heating a fluid

What does the formula (Fe, Mg)SiO4 for olivine indicate?

• The mineral contains Fe or Mg, but not both

• The amounts of Fe and Mg in the mineral are equal

• The mineral took Fe and Mg from the magma as it formed

• The mineral loses Fe and gains Mg over time

The most common mineral created by living organisms is (a)   .

• Quartz
• Apatite
• Calcite
• Dolomite

When a mineral precipitates from solution, it:

• Shrinks in size

• Likely will seep into the ground

• Forms a crystal

• Eventually evaporates
