D)in a valley

Question

Quizplus · Accepted Answer

Metamorphic rocks are formed from pre-existing rocks that have undergone a change in response to high temperature and pressure conditions. Such conditions are typically found deep within the lithosphere, where tectonic forces and/or magma chambers can cause heat and pressure to rise significantly. They are less likely to be found on the seafloor or in a valley, which are typically areas of lower temperature and pressure. While some metamorphic rocks may be associated with volcanic mountain ranges, this is not a necessary condition for their formation.
