Medamorphic rock is created by lava and magma.

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.

Metamorphic rock is created by magma, heat, and pressure.

metamorphic starts out as a different then changes with pressure and heat

Metamorphic is made from magma and lava.

Lava and Magma is created into a metamorphic rock

Metamorphic rocks change from one to another through heat and pressure.

metamorphic rock is created when rocks change into other rock.

I mean heat and pressure

Metamorphic rocks is created by heat and pressure.And the types are foliated and nonfoliated

Metamorphic rocks are formed by heat and pressure.

Metamorphic rocks have been modified by heat, pressure and chemical process usually while buried deep below Earth's surface. Exposure to these extreme conditions has altered the mineralogy, texture and chemical composition of the rocks. There are two basic types of metamorphic rocks: 1) foliated metamorphic rocks such as gneiss, phyllite, schist and slate which have a layered or banded appearance that is produced by exposure to heat and directed pressure; and, 2) non-foliated metamorphic rocks such as marble and quartzite which do not have a layered or banded appearance. Pictures and brief descriptions of some common types of metamorphic rocks are shown on this page.

Metamorphic rocks morphed with rocks igneous or sedimentary rocks.

Metamorphic rock, is made from lots of heat and pressure.

Ella T. said...

Metamorphic rocks are formed when sediments sink into the Earth, then heat and pressure compact the sediments creating layers, and then once it's cooled, it becomes a metamorphic rock.

when anouther rock gets alot of heat and pressure it turns into a metamorphic rock thatshow a metamorphic rock is created.
