Metamorphic Rock

Front

What is a metamorphic rock?

Back

A metamorphic rock is a type of rock that has been changed from its original form due to high heat, high pressure, or chemically active fluids.

Front

Which rock is an example of a metamorphic rock?

Back

Schist is an example of a metamorphic rock.

Front

What are the two main types of metamorphic rocks?

Back

The two main types of metamorphic rocks are foliated and nonfoliated.

Front

What characterizes foliated metamorphic rocks?

Back

Foliated metamorphic rocks have visible bands or layers.

Front

What characterizes nonfoliated metamorphic rocks?

Back

Nonfoliated metamorphic rocks do not have visible bands or layers.

Front

How are metamorphic rocks classified?

Back

Metamorphic rocks are classified by their texture (foliated or nonfoliated).

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

True or False: The deeper a rock is buried, the greater the pressure on it.

Back

True.

Front

What is the role of heat in the formation of metamorphic rocks?

Back

Heat causes the minerals in the rock to recrystallize, leading to changes in texture and mineral composition.

Front

What is the role of pressure in the formation of metamorphic rocks?

Back

Pressure can cause the minerals in the rock to become denser and can also lead to foliation.
