Quizplus · Accepted Answer

Metamorphism most commonly takes place in the solid state, meaning that the rock remains in its solid form during the process. Fluid activity, such as the presence of hot water or other solutions, can enhance the process, but it still occurs in the solid state. While metamorphism can occur at great depths, it can also occur at shallower depths, depending on the conditions. Magma can also initiate metamorphism, but it does not have to be in direct contact with the rock, and it is not necessary for metamorphism to occur only at great depths. Therefore, only choice B accurately describes metamorphism.
