Front

What are metamorphic rocks?

Back

Metamorphic rocks are rocks that have been changed from their original form due to extreme heat, pressure, or chemically active fluids.

all types of rocks.

Front

What causes the extreme heat during the formation of metamorphic rocks?

Back

The extreme heat is usually caused by the fiery hot magma in the Earth's mantle.

What is the texture of foliated metamorphic rocks?

Back

Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals.

Front

What type of environment do metamorphic rocks typically form in?

Back

Metamorphic rocks typically form in environments with high heat and high pressure.

Front

What is nonfoliated metamorphic rock?

Back

Nonfoliated metamorphic rock is a type of metamorphic rock that does not have a layered or banded appearance.

Front

What is the role of tectonic plates in the formation of metamorphic rocks?

Back

The collision of tectonic plates can create the extreme pressure and heat necessary for the formation of metamorphic rocks.

Front

How does sedimentary rock become a metamorphic rock?

Back

Sedimentary rock can become a metamorphic rock through the processes of heat and pressure over time.
