What is the name of the type of metamorphism in which molten magma intrudes into the upper, relatively cold part of the Earth's crust?
Understand the Problem
The question is asking for the specific term used to describe a type of metamorphism that occurs when molten magma intrudes into the cooler upper part of the Earth's crust.
Answer
Contact metamorphism.
The type of metamorphism where molten magma intrudes into the upper, relatively cold part of the Earth's crust is called contact metamorphism.
Answer for screen readers
The type of metamorphism where molten magma intrudes into the upper, relatively cold part of the Earth's crust is called contact metamorphism.
More Information
Contact metamorphism occurs when existing rocks are subjected to high temperatures but relatively low pressures, typically around intrusive igneous activities like magma intrusions.
Tips
A common mistake is confusing contact metamorphism with regional metamorphism, which involves high pressure and temperature over large areas.
