Contact metamorphism _____.
1.) is caused by high temperatures
2.) usually affects a very large area
3.)happens when mountains are formed
4.)occurs along fault lines

The answer is in this paragragh!!!!!!

[Diagram of location where contact metamorphism occurs] Contact metamorphism also happens at low pressure, but at high temperature. Magma from an intrusion contacts preexisting rock. It seeps into tiny spaces and heats the rock. Contact metamorphism affects a small area and forms fine-grained, non-foliated rock.
