Question

Quizplus · Accepted Answer

Metamorphism is caused by changes in the physical and sometimes chemical conditions of a rock, primarily through heat, pressure, and the activity of fluids. These processes alter the mineralogy and texture of the rock, transforming it into a metamorphic rock. Weathering, melting, and crystallization are not processes that cause metamorphism; instead, weathering breaks down rocks, melting leads to the formation of igneous rocks, and crystallization is a process that can occur during the cooling of magma or the precipitation of minerals from solutions, not specifically related to metamorphism.
