Question

Quizplus · Accepted Answer

Metamorphic rocks are formed from pre-existing rocks that undergo a physical or chemical change due to high pressure and/or temperature. Deep burial can exert such high pressure on rocks to cause them to recrystallize and form metamorphic rocks, such as marble or slate. Sedimentary rocks are formed from the accumulation of sediment, chemical rocks form from precipitation of minerals, and igneous rocks form from the cooling and solidification of magma or lava.
