Metamorphic rock forms when:
A) seawater precipitates.
B) sediments are lithified.
C) magma cools and solidifies.
D) igneous, sedimentary, or other metamorphic rocks change because of high temperature and/or pressure, or compositional changes, or are deformed during mountain building.

Question

Quizplus · Accepted Answer

Metamorphic rock forms when pre-existing rocks, such as igneous, sedimentary, or other metamorphic rocks, undergo changes due to high temperature and/or pressure, or compositional changes, or are deformed during mountain-building processes. This can result in the formation of new minerals and texture changes in the rock. Seawater precipitation can lead to the formation of sedimentary rocks, while magma cooling and solidification results in the formation of igneous rocks.
