Metamorphic Rocks Flashcard

Front

What is a metamorphic rock?

Back

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

Front

What is the parent rock of Quartzite?

Back

The parent rock of Quartzite is sandstone, which is primarily composed of quartz grains.

Front

What process primarily changes rocks during contact metamorphism?

Back

During contact metamorphism, rocks are primarily changed by heat from magma.

Front

What is regional metamorphism?

Back

Regional metamorphism is the process where rocks are changed over large areas due to high pressure and temperature, typically associated with tectonic forces.

Front

What is contact metamorphism?

Back

Contact metamorphism occurs when magma intrudes into existing rock, heating and altering it.

Front

What is the role of pressure in metamorphic rock formation?

Back

Pressure plays a crucial role in metamorphic rock formation by causing physical and chemical changes in the rock structure.

Front

What type of metamorphism occurs at tectonic plate boundaries?

Back

Regional metamorphism occurs at tectonic plate boundaries due to the immense pressure and heat generated.

Front

What is the difference between contact and regional metamorphism?

Back

Contact metamorphism is localized and caused by heat from magma, while regional metamorphism affects larger areas due to pressure and temperature changes.

Front

What is the significance of hot chemical fluids in metamorphism?

Back

Hot chemical fluids can facilitate the metamorphic process by introducing new minerals and altering the chemical composition of the rock.

Front

What type of rock is formed from limestone through metamorphism?

Back

Marble is formed from limestone through the process of metamorphism.
