Contact metamorphism occurs over a localized area when magma moves into the crust. true or false

TRUE

Explanation:

When the hot and less dense magma rises up towards the surface, the country rocks are heated due to the increasing temperature of the magma. This results in the formation of an aureole that surrounds the intruded magma body. This aureole is commonly known as the metamorphic aureole and contact metamorphism occurs in this area. This type of process occurs at a comparatively smaller area, and where there is a high temperature and low-pressure condition. For example, Hornfels and Marble.

Thus, the above-given statement is True.
