What is made up of rock that has undergone great heat and pressure?
Metamorphic rock
Are some rocks metamorphic AND sedimentary?
No. If a sedimentary rock has undergone even a low grade metamorphism, it is considered a metamorphic rock.
How can an igneous rock become a metamorphic?
A metamorphic rock can become a igneous rock by melting and cooling
What change has occurred to metamorphic rock?
Metamorphic rock has undergone changes in temperature, pressure, or chemical composition, causing it to recrystallize and form new minerals.
Marble was an metamorphic rock that was origanally what?
Marble was an metamorphic rock that was originally a sedimentary rock, which consist of limestone that has undergone heat and pressure metamorphosis under temperatures in excess of 1800ºF.
What is a rock that has undergone change?
A rock that has undergone change is called a metamorphic rock. This type of rock forms under high pressure and temperature conditions, causing the original rock to change its mineral composition and texture. Examples of common metamorphic rocks include marble (from limestone) and schist (from shale).
What refers to how much the metamorphic rock differs from parent rock?
Metamorphic grade refers to the degree of metamorphic change a rock has undergone compared to its parent rock. It encompasses changes in mineralogy, texture, and structure that occur during the metamorphic process.
What part of the rock cycle is marble at now?
Marble is a metamorphic rock, which means it has undergone transformation from its original rock form through heat and pressure. In the rock cycle, marble is currently in the metamorphic rock stage.
For metamorphic rock to become igneous rock what steps are necessary?
Metamorphic rock can not become igneous rock, however igneous rock can become metamorphic. This process happens over time as the rocks are shifted, compressed and heated by the Earth.
What can a metamorphic rock become?
A pre-existing, igneous, sedimentary and metamorphic rock.
What rocks change into metamorphic rocks?
