1. Explain the characteristics that distinquish how metamorphic rocks are classified.

2. Explain that metamorphic rocks are most important due to their economic uses and in hard rock mining.

Multiple Choice

Which type of rock is formed by the cooling and crystallizing of molten rock?

• Igneous

• Sedimentary

• Metamorphic

Multiple Choice

Which type of rock can form from living things, pieces of other rocks, and minerals dissolved in water?

• Igneous

• Sedimentary

• Metamorphic

Multiple Choice

Which type of rock can ONLY form from pre-existing protoliths (parent rocks)?

• Igneous

• Sedimentary

• Metamorphic

Multiple Choice

During metamorphism the minerals melt due to the extreme heat and pressure

• True

• False

Multiple Choice

Limestone contains the mineral calcite which dissolves in acid.

Limestone is the parent rock of Marble.

Will Marble also dissolve with acid?

• Yes

• No

Multiple Select

What happens to the minerals in a rock when it becomes a metamorphic rock?

• They precipitate

• They re-crystallize

• They are forced out

• They stay the same

Multiple Choice

When Magma is forced up into existing layers of rocks beneath the surface:

• Subduction

• Hot Spot

• Igneous Intrusion

• Rock Invasion

Multiple Choice

Metamorphic rocks are often formed at convergent boundaries where 2 continents smash together and form:

• Volcanoes

• Folded Mountains

• Islands

• Ocean Trenches

Multiple Select

Which 2 factors cause metamorphism?

• Intense Heat

• Extreme Pressure

• Excessive Erosion

• Strong Weathering

Multiple Choice

Where are almost all Metamorphic rocks formed:

• On Earth's surface

• Below Earth's Surface

Multiple Choice

Collision and subduction zones are where Earth's tectonic plates are pushed together. These areas cause:

• Contact metamorphism

• Regional Metemorphism

Multiple Choice

Igneous intrusions force magma into rocks underground. The touching hot magma causes:

• Contact metamorphism

• Regional Metemorphism

Multiple Choice

Which is NOT a source of extreme pressure responsible for metamorphism?

• Igneous intrusions

• Gravity

• Earth's moving crust

• Lava

Multiple Choice

Which is NOT associated with metamorphic rocks?

• Stratification

• Foliation

• Re-crystallization

• Change

Multiple Choice

Classification of Marble?

• Foliated

• Non-foliated

Multiple Choice

Classification of Slate?

• Foliated

• Non-foliated

Multiple Choice

Classification of Gneiss?

• Foliated

• Non-foliated

Multiple Choice

Classification of Quartzite?

• Foliated

• Non-foliated

Multiple Choice

What happens when foliation occurs?

• The rock gets compressed and denser

• The minerals arrange in bands (stripes)

• Minerals re-crystallize

• All of these processes occur during foliation

Multiple Choice

Which is a higher quality of coal that will produce more heat energy?

• Anthracite Coal

• Bituminous Coal
