11) Igneous rocks can go three different ways. Under heat + pressure, it can turn into a metamorphic rock, if it starts melting, it can form back into melting, or with weathering and erosion, it could turn into sediments and then into a sedimentary rock.
12) B<span>ecause crystals in granite had more time to form as the magma cooled slowly. C</span><span>rystals that form on the surface are tiny because they cooled very quickly T</span><span>he more time crystals have to form, the more likely they are going to be larger in size</span>
B. is the correct answer. please mark as brainiest
; )
The heat causes contact metamorphism. The correct option among all the options that are given in the question is the first option or option "A". Contact metamorphism is the type of metamorphism that is caused due to proximity or contact with an igneous intrusion. I hope the answer has helped you.
