2. Introduction
Have you ever wondered what a
metamorphic rock is? Are you about
to explode, because you don’t know
how a metamorphic rock is formed?
Well if you read on, you will find out
everything about a metamorphic
rock that you’ve been wanting to
know!
3. What Is A
Metamorphic Rock?
A metamorphic rock is a rock that has been
changed in shape.
Before the components of a metamorphic rocks
are Igneous, Sedimentary, Metamorphic or other
types of rocks pushed together by gravity and
pressure.
The texture might even have no sign of its
components, but will have crystallizations.
4. One Kind Of Metamorphic
Rock- Marble
Marble is a metamorphic rock that comes from
metamorphosed limestone, calcite, or dolomite.
Color: Various but usually gray or white.
Marble is usually used for making sculptures and flooring.
Marble tends to be considered an elegant material. It is also
tied closely to the classical Greek and Roman periods. A
relatively expensive, and difficult to maintain stone, it is most
often used in delicate and upscale applications.
5. Another Kind Of
Metamorphic Rock-
Quartzite
Quartzite is a coarse-grained metamorphic rock
derived from sandstone.
Color: Usually white, light gray, yellowish, or light
brown.
Quartzite is used for floorings, construction materials
and is part of the ingredients in glass.
It has a uniform texture and is very hard, 7 on the Mo's
Scale.
6. Last Kind Of Metamorphic
Rock That We Will Define-
Gneiss
Gneiss is a medium to course grained metamorphic rock.
Color: Usually black and white.
Gneiss is used for gravestones, and flooring material.
Gneiss is found in New England, the Piedmont (Part of
North America), the Adirondacks, and the Rocky Mts. Some
gneisses are used as facing stone on buildings.
7. Properties Of A
Metamorphic Rock
Metamorphic rocks are composed of Ingenious,
Sedimentary, Metamorphic or any other kind of
rock pushed together by gravity, heat, and
pressure.
8. Glossary
Metamorphic- A metamorphic rock is a rock that has
been changed in shape.
Heat- Heat is when something turns very hot and
melts into hot liquid.
Crystallization- When hot liquid freezes. This
hardens into different shapes and lusters.
Pressure- Is when something or someone is using
much force to push or move an object and is the
friction from pushing or moving the object.
