Identify ONE Process That Causes The Metamorphism Of An Igneous Rock Into A Metamorphic Rock class=

Answer :

Answer:

Heat

Explanation:

 Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.

Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.

What is metamorphic rock?

Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.

Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.
