Metamorphic rocks are rocks that?
Usually have a rougher texture
What describes the thin flat layering in most metamorphic rocks?
The thin flat layering found in most metamorphic rocks is called foliation
What sound does two metamorphic rocks make when they hit together?
Listen to: Tangerine Dream - Thru Metamorphic Rocks
Metamorphic rocks that are nonfoliated?
Usually have a rougher texture
How does metamorphic rocks become an igneous rock?
they are melted together
How do metamorphic rocks form from metamorphic rocks?
Sedimentary rocks form from layers of sand, silt or clay, sometimes mixed with pebbles, and the bodies of living things (that may the be fossilised) The rocks are often quite soft. Metamorphic rocks form when rocks (usually sedimentary rocks) are subjected to extreme heat and/or pressure, usually deep underground. The rocks are changed in form, often becoming harder. Fossils are usually destroyed by the process.
How do geologists classify metamorphic rock?
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
What are the texture groups for metamorphic rocks?
usually smooth i think.
What are metamorphic rocks created by?
Metamorphic rocks are created by the transformation of existing rocks through heat, pressure, or chemical processes without melting. This process usually occurs deep within the Earth's crust or mantle.
What needs to be applied to igneous or sedimentary rocks to form metamorphic rocks?
Metamorphic rock is usually formed from the application of heat and/or pressure to existing rock.
What rocks have foliated structure?
"Foliated" rocks are usually metamorphic rocks like phyllite, slate, schist, and gneiss.
What do the crystals in metamorphic rocks look like?
they are put together and squated
