Quizplus · Accepted Answer

Metamorphic rocks are formed by the alteration of existing rocks through heat, pressure, or a combination of both. This process changes the mineral composition and physical properties of the rock. Sedimentary rocks are formed by the accumulation and lithification of sediments, while igneous rocks are formed by the cooling and solidification of magma or lava. Plutonic rocks are a type of igneous rock that forms below the Earth's surface, and extrusive igneous rocks are formed by volcanic activity above the Earth's surface.
