How are Metamorphic Rocks Formed Quizlet
Metamorphic rocks are a type of rock that forms when existing rocks are subjected to high pressure and temperature conditions, causing changes in their mineral composition and structure.
The Process of Metamorphism
Metamorphism occurs when sedimentary or igneous rocks are buried deep within the Earth’s crust, often due to tectonic forces such as plate convergence or mountain building. As the rocks are subjected to increasing pressure and temperature, they undergo changes that can lead to the formation of new minerals and textures.
Factors Affecting Metamorphism
The rate and extent of metamorphism depend on several factors, including:
- Pressure:** As rocks are buried deeper, pressure increases, leading to changes in their mineral composition.
- Temperature:** High temperatures can cause minerals to recrystallize or form new ones.
Kinds of Metamorphism
There are several types of metamorphism that occur under different conditions:
Isobaric Metamorphism
This type of metamorphism occurs when rocks are subjected to increasing pressure at a constant temperature, resulting in changes such as recrystallization and the formation of new minerals.
The Types of Metamorphic Rocks
Metamorphic rocks can be classified into several categories based on their mineral composition and texture:
Schistosity
This type of metamorphism results in the formation of schist, a type of metamorphic rock characterized by its platy or flaky texture.
The Importance of Metamorphic Rocks
Metamorphic rocks play a crucial role in our understanding of the Earth’s history and the processes that shape our planet:
These rocks provide valuable information about the conditions under which they formed, including temperature, pressure, and time.
