Question

Quizplus · Accepted Answer

Metamorphic grade refers to the intensity of metamorphism, which can be determined by the presence of specific minerals that are sensitive to temperature and pressure. The higher the grade, the more intense the metamorphism and the greater the change in the original rock. Option A is incorrect because economic value depends on various factors such as availability, demand, and use. Option B is a joke and not related to the question. Option D is incorrect because recrystallization and original grain size are factors that affect texture, not grade.
