Metamorphic Rocks

Where can most metamorphic rock be found?

• As part of mountain ranges

• At the bottom of oceans

• Lake beds

• Deep in the Earth, near the mantle

Which of the following are mechanisms that drive metamorphism?

• heat

• confining pressure

• erosion

• lithification

At a continental-continental convergent boundary, which type of metamorphism should be occurring?

• contact metamorphism, due to the intense heat of the magma chamber

• regional metamorphism, due to the intense heat of the magma chamber

• regional metamorphism, due to the intense pressure

• contact metamorphism, due to the intense pressure

Many metamorphic rocks resemble most closely:

• Coarse-grained igneous rocks

• Fine-grained igneous rocks

• Detrital sedimentary rocks

• Chemical sedimentary rocks
