Earth Science Chapter 3

Which of the following is true about rocks?

• Rocks are composed of only one mineral.

• Rocks do not contain any mineral matter.

• Coal is not considered a true rock.

• Most rocks are a mixture of minerals.

Which of the following is NOT one of the three types of

rock?

• igneous

• sedimentary

• magma

• metamorphic

Metamorphic rock forms as a result of

• heat and pressure.

• the cooling of magma.

• compaction of sediments.

• the melting of rock.

All of the energy that drives Earth’s rock cycle comes from

• the wind.

• Earth’s interior and the sun.

• the breakdown of organic matter.

• the movement of water over Earth’s surface.

processes responsible for the formation of sedimentary

rocks?

• erosion, weathering, compaction, cementation, deposition

• compaction, cementation, deposition, weathering, erosion

Sedimentary rocks with ripple marks suggest that the rocks

formed

• along a beach or stream bed.

• when an ancient animal swam over them.

• from shell fragments of ancient sea-dwelling animals.

• when wet mud dried and shrank.

What rock-forming process occurs when hot magma forces

its way into rock?

• regional metamorphism

• biochemical sedimentation

• contact metamorphism

• deposition

A foliated metamorphic rock forms when crystals

• combine but do not form bands.

• combine and form visible bands.

• become less compact.

• align themselves parallel to the direction of the forces

  acting on them.
