Question
What does the metamorphic grade of a rock tell you?A.How far the rock is from its original locationB.How steep the slope that contains the rock isC.How much rock went through metamorphosisD.How high the temperature was during metamorphism
Solution
The metamorphic grade of a rock tells you D. How high the temperature was during metamorphism.
The metamorphic grade refers to the intensity of metamorphism that the rock has undergone. This is determined by the heat and pressure conditions that the rock was subjected to. Low-grade metamorphism occurs at relatively low temperatures and pressures, while high-grade metamorphism takes place at high temperatures and pressures. The minerals that form during these different conditions can be used to estimate the metamorphic grade.
