Describe what a metamorphic rock is
WebMetamorphic rocks that are not layered are called massive or isotropic . There are several types of foliations: Compositional layering - Foliation defined by alternating layers composed of different minerals. Always easily recognized by differences in color of layers. WebMetamorphic rocks have been subjected to tremendous heat and/or pressure, causing them to change into another type of rock. They are usually resistant to weathering and erosion and are...

WebMetamorphic rocks, meta- meaning change and – morphos meaning form, is one of the three rock categories in the rock cycle (see Chapter 1 ). Metamorphic rock material has been changed by temperature, pressure, and/or fluids. The rock cycle shows that both igneous and sedimentary rocks can become metamorphic rocks. WebMetamorphic rocks are formed from other rocks which change due to heat or pressure. The original rocks are usually sedimentary rocks or igneous rocks. Sometimes one metamorphic rock...

The melt originates deep during the Earth near active plate boundary or hot blot, then rises toward and surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the liquified sway solidifies.Intrusive Fiery … WebRegional metamorphism is associated with the major events of Earth dynamics, and the vast majority of metamorphic rocks are so produced. They are the rocks involved in the cyclic processes of erosion, sedimentation, burial, metamorphism, and mountain building ( orogeny ), events that are all related to major convective processes in Earth’s mantle.
WebSep 3, 2024 · Metamorphic rocks start off as igneous, sedimentary, or other metamorphic rocks. These rocks are changed when heat or pressure alters the existing rock’s physical or chemical make up. One ways rocks may change during metamorphism is by rearrangement of their mineral crystals.
