What interpretation can be made from an igneous rock body such as granite) that has baked or metamorphosed the adjacent rocks?
A) When the granite was molten, the heat from the magma altered the preexisting rocks around it.
B) The adjacent rocks reacted with the solid granite to create a zone of metamorphism.

Question

Quizplus · Accepted Answer

Granite, when in its molten form (magma), can release a significant amount of heat. This heat is capable of altering the surrounding preexisting rocks, a process known as contact metamorphism. This occurs because the high temperatures from the molten granite are sufficient to change the mineral composition and texture of the adjacent rocks without melting them completely.
