• Sedimentary

• Bituminous

• Igneous

• Metamorphic

Multiple Choice

When rocks undergo weathering, they become

• Magma

• Igneous rocks

• Sediment

• Volcanic cones

Multiple Choice

The formation of metamorphic rocks depends on all of the following except

• The composition of the parent rocks.

• Earth's magnetic field.

• Temperature

• Pressure

Multiple Choice

Rocks found on Earth are generally classified as sedimentary, metamorphic, or igneous. On which basis are these classifications made?

• Where the rocks are found

• How the rocks were formed

•  The color and shape of the rocks

• The chemical composition of the rocks

Multiple Choice

A student wants to study how igneous rock changes to sedimentary rock. Is this a good project if the student needs to complete the study within a month?

• Yes because the changes will happen quickly and be significant.

• Yes because the changes will be easily observed since they are very obvious.

• No because the difference between igneous rock and sedimentary rock is not noticeable.

• No because the changes will take much longer than a month to occur.

• Intrusive

• Extrusive

• Foliated

• Nonfoliated

Multiple Choice

During a summer vacation in Hawaii, Carlos found several rock samples to share with his Earth Science class. Most of the rocks were black, containing only few light colored crystals. All of the crystals were large and the rocks had a coarse texture. Based on this information which of the following statements is true about the rocks Carlos found?

• The rocks were obsidian.

• The rocks were extrusive.

• The rocks were intrusive.

• The rocks were metamorphic.

Multiple Choice

What is the difference in a rock and a mineral?

• A rock is made of only one mineral.

• A mineral is made of only one mineral and a rock is made of many minerals.

• A rock is harder than a mineral.
