Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A metamorphic rock can also be thought of as rock that changes. What causes the rock to change?
A
Layers of sediment building up over time and pressing down, forming rock
B
rain, wind, freezing, thawing, and plant roots growing cause the rock to erode away, leaving behind sediment
C
Extreme heat and pressure from deep within earth cause changes to the rock’s appearance, structure, and composition.
D
the rock slowly changes over time into a new rock
Explanation: 

Detailed explanation-1: -During metamorphism the mineral content and texture of the protolith are changed due to changes in the physical and chemical environment of the rock. Metamorphism can be caused by burial, tectonic stress, heating by magma, or alteration by fluids.

Detailed explanation-2: -Process of Metamorphism: New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks. Pressure or temperature can even change previously metamorphosed rocks into new types. Metamorphic rocks are often squished, smeared out, and folded.

Detailed explanation-3: -At a certain depth, temperature and pressure are so high that it may affect the mineralogy, texture or chemical composition of rocks. Rocks undergo a process called metamorphism. Most metamorphic rocks are produced in the middle and lower crust at a depth of 10 to 30 km.

Detailed explanation-4: -Which among the following statement(s) is true about metamorphic rocks? They are formed when rocks change their original shape and form due to intense heat or pressure.

Detailed explanation-5: -formation: when parent rocks are squeezed (pressured), heated, or exposed to hot fluids. flat shaped caused by foiliation results when uneven pressures cause flat minerals to line up giving the rock a layered appearance.
