Metamorphic Rocks Lesson

Metamorphic Rocks Lesson

By Eryn Keating

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
