Metamorphic Rocks Quiz

What conditions lead to the formation of metamorphic rocks?

• Low pressure and low temperature

• High heat, high pressure, and mineral-rich fluids

• Freezing temperatures and high winds

• Low humidity and high altitude

Which of the following is NOT a common metamorphic rock?

• Phyllite

• Schist

• Basalt

• Marble

What happens to metamorphic rocks under high pressure?

• They melt into magma

• They become squished, smeared out, and folded

• They evaporate

• They turn into sedimentary rocks

What is recrystallization in metamorphic rocks?

• Formation of new minerals without melting

• Melting of original minerals

• Formation of layers in rocks

• Creation of a porous structure

Which of the following is a characteristic of foliation in metamorphic rocks?

• Uniform structure

• Layered or banded appearance

• Porous texture

• Random mineral alignment

Which of the following rocks is an example of a non-foliated metamorphic rock?

• Schist

• Gneiss

• Marble

• Slate

What causes the formation of foliation in metamorphic rocks?

• Random pressure

• Alignment of minerals under directional pressure

• Melting of minerals

• Cooling of magma

What is Regional Metamorphism?

• Occurs over large areas due to tectonic forces creating high pressure and heat

• Occurs when rocks are heated by nearby magma or lava

• Happens when hot, mineral-rich water flows through rock fractures

• Occurs in small, localized areas with low pressure

What causes Contact Metamorphism?

• High pressure and heat over large areas

• Nearby magma or lava heating rocks

• Mineral-rich water altering rock composition

• Erosion and weathering of rocks

How does Hydrothermal Metamorphism occur?

• Through tectonic forces creating high pressure

• By nearby magma or lava heating rocks

• When hot, mineral-rich water flows through rock fractures

• Due to volcanic eruptions
