Earth Science Unit 6 Review

A rock that contains a fossil is most likely

• igneous.
• sedimentary.
• metamorphic.
• felsic.

The large, well-developed crystals found in some samples of granite are a sign that

• the magma from which it formed cooled rapidly.
• the magma contained a lot of dissolved gases.
• the magma from which it formed cooled slowly.
• water deposited minerals in the rock cavities.

How does coal differ from breccia?

• Coal is an example of sedimentary rock, and breccia is an example of metamorphic rock.
• Coal is an example of metamorphic rock, and breccia is an example of igneous rock.
• Coal is an example of organic rock, and breccia is an example of clastic rock.
• Coal is an example of clastic rock, and breccia is an example of a conglomerate.

Which term describes the metamorphic rock texture in which minerals are arranged in bands?

• Stratification
• Cementation
• Foliation
• Precipitation

What occurs when heat from nearby magma causes changes in the surrounding rocks?

• Contact metamorphism
• Fluid metamorphism
• Intrusive metamorphism
• Regional metamorphism

What type of sedimentary rock is formed when angular clastic materials cement together?

• Chemical
• Organic
• Breccia
• Conglomerates

What type of rock is formed when heat, pressure, and chemical processes change the physical properties of igneous rock?

• Igneous
• Metamorphic
• Sedimentary
• Sandstone

The splitting of slate into flat layers illustrates its

• contact metamorphism.
• formation.
• sedimentation.
• foliation.

One example of chemical sedimentary rock is

• an evaporite.
• coal.
• sandstone.
• breccia.

One example of an extrusion is a

• stock.
• dike.
• batholith.
• lava plateau.
