What processes were involved in the formation of the model? How is the model similar to the real metamorphic sample? How is the model different from the real metamorphic sample?

Metamorphic Rock - Forms when pressure, temperature, or chemical processes change existing rock. Igneous Rock - forms when magma or lava cools and hardens to become solid. Sedimentary Rock - Form when minerals that form from solutions or sediment from older rocks get pressed and cemented together. The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Hope this helps!
