Metamorphic Rocks and Processes Quiz

What is the primary process that changes a rock into a metamorphic rock?

• Erosion

• Metamorphism

• Sedimentation

• Volcanism

Why is metamorphism not typically observed at Earth's surface?

• It requires volcanic activity

• It is a rapid process

• It occurs deep within the Earth

• It only happens in oceanic crust

What are the three major variables in forming metamorphic rocks?

• Temperature, pressure, and fluids

• Wind, water, and ice

• Sunlight, air, and soil

• Gravity, magnetism, and electricity

What is foliation in metamorphic rocks?

• A form of sedimentation

• Apparent layering due to stress

• A process of erosion

• A type of mineral

How is a slate different from a shale?

• Slate is softer and more crumbly

• Slate is a type of igneous rock

• Slate is harder and used for roofing

• Slate is formed by volcanic activity

What type of metamorphism occurs when an igneous rock alters surrounding rocks?

• Contact metamorphism

• Fault metamorphism

• Regional metamorphism

• Shock metamorphism

Which type of metamorphism is associated with tectonic plate collisions?

• Contact metamorphism

• Shock metamorphism

• Regional metamorphism

• Fault metamorphism

What is shock metamorphism?

• Metamorphism due to volcanic eruptions

• Metamorphism due to ocean currents

• Metamorphism caused by meteor impacts

• Metamorphism from tectonic shifts

What is the significance of shocked quartz in geology?

• It indicates volcanic activity

• It shows evidence of meteor impacts

• It is a sign of tectonic movement

• It forms during sedimentation

How do metamorphic rocks complete the rock cycle?

• By turning back into molten rock

• By transforming into sedimentary rocks

• By forming new igneous rocks

• By being weathered and eroded
