Metamorphic Rocks

Front

What are metamorphic rocks?

Back

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

Front

How do metamorphic rocks form?

Back

Metamorphic rocks form from all types of rocks: igneous, sedimentary, and other metamorphic rocks.

Front

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

Back

The deeper a rock is buried in the Earth's crust, the greater the pressure on that rock, which can lead to metamorphism.

Front

What is foliation in metamorphic rocks?

Back

Foliation is a texture in metamorphic rocks where minerals are aligned in layers or bands.

Front

What is a non-foliated metamorphic rock?

Back

Non-foliated metamorphic rocks do not have a layered or banded appearance and are typically composed of one mineral.

Back

Marble is an example of a non-foliated metamorphic rock.

Front

What is the difference between igneous and metamorphic rocks?

Back

Igneous rocks form from the cooling and solidification of magma or lava, while metamorphic rocks form from the alteration of existing rocks due to heat and pressure.

Front

What is the significance of temperature in metamorphism?

Back

Temperature increases can cause minerals in rocks to recrystallize, leading to the formation of metamorphic rocks.

Front

What are the two main types of metamorphism?

Back

The two main types of metamorphism are contact metamorphism and regional metamorphism.
