Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change as rocks.
Metamorphic rocks can be found on the surface in the highly eroded features of old mountains, in upwardly thrust exposures at certain beach areas, and in glacial drift they can be found as erratics, rocks that are not native to an area. Metamorphic Rocks can be found in the Earth's crust. In fact, a lot of Earth's crust is made up of metamorphic rocks. Metamorphic rocks are the rarest of the three types.(Sedimentary,Igneous, Metamorphic)
Metamorphic rock really is found deep underground, at the base of mountains, in zones radiating from intrusions of magma underground, on glaciated terrain after transportation by ice, or on the surface of eroded mountains.
Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are. this is how they are formed.
It is just a change in existing rock, when its above 150 degrees Celsius, and pressure is above 1500 bars. All this causes changes in the Physical and/or chemical state.
You would mainly find this occurring in the earths interior.
Metamorphic rock is formed deep underneath the earth's surface, where it is under tons of pressure. Sedimentary and igneous rock slowly sink farther and farther down beneath the earth's surface until they are under so much pressure, they change into a new kind of rock, which would be a metamorphic rock.
they can be found anywhere, even under water;considering th fact that pres-
ent day oceans were not always oceans.
Quartzite is a metamorphic rock formed from sandstone.
Marble is the metamorphic rock formed from limestone. =)
Rock can be changed into metamorphic rock by heat and pressure.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Hornfels or gneiss are possible metamorphic rock with a greywacke protolith.
Quartzite is a metamorphic rock formed from sandstone.
Metamorphic Rock
Probably the metamorphic rock phyllite.
metamorphic.
Marble is the metamorphic rock formed from limestone. =)
both are correct metamorphic rock can form from both.
Rock can be changed into metamorphic rock by heat and pressure.
Slate is formed out of a sedimentary rock called Shale. It is a foliated metamorphic rock.
Metamorphic rocks are formed from sedimentary rocks.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Slate is a metamorphic rock formed from the parent rock shale.
