Metamorphic Rocks

Front

What are metamorphic rocks?

Back

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

Front

What is the process of metamorphism?

Back

Metamorphism is the process by which existing rocks are transformed into metamorphic rocks through heat, pressure, and/or chemical processes.

Front

What is the parent rock of slate?

Back

The parent rock of slate is shale.

Front

What type of metamorphism occurs due to heat from magma?

Back

Contact metamorphism occurs when magma heats the surrounding rock and changes it.

Front

What is the role of pressure in metamorphism?

Back

Pressure increases with depth in the Earth's crust, which can cause rocks to change their structure and composition.

Front

True or False: Heat and pressure can change sedimentary rock shale into slate.

Back

True.

Front

What is regional metamorphism?

Back

Regional metamorphism occurs over large areas under high pressure and temperature, often associated with tectonic forces.

Front

What is the difference between contact and regional metamorphism?

Back

Contact metamorphism occurs near magma, while regional metamorphism affects larger areas due to tectonic processes.

Front

What type of rock can be transformed into marble?

Back

Limestone is the parent rock that can be transformed into marble through metamorphism.

Front

What is foliation in metamorphic rocks?

Back

Foliation is the alignment of mineral grains in a metamorphic rock, often resulting in a layered appearance.
