Detailed explanation-1: -She wanted to know what could cause a sedimentary rock to become a metamorphic rock. Which processes must occur in order for a sedimentary rock to change into a metamorphic rock?-compaction and cementation.

Detailed explanation-2: -Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Detailed explanation-3: -Extrusive, or volcanic, igneous rocks are formed when molten hot material cools and solidifies. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes-such as melting, cooling, eroding, compacting, or deforming-that are part of the rock cycle.

Detailed explanation-4: -The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Detailed explanation-5: -A rock cycle is a fundamental concept that shows the transitions among the three basic rock types (metamorphic, igneous and sedimentary). In simple terms, it is a chain of processes that produce and transform the rock types in Earth’s crust.
