How is a metamorphic rock formed?

Explanation:

igneous, sediments, composition and grain size

Metamorphic rocks are formed from pre-existing rocks altered through heat and pressure.

Explanation: Metamorphic rocks are rocks produced when either igneous rocks or sedimentary rocks are been altered through the action of heat and pressure to produce a rock that have metamorphosize.

1. The answer is; buried deep within

The deeper you go into the earth’s crust, the higher the pressure. This is due to the weight of the overlying layers of rock. Due to this pressure, there is also great heat. This heat and pressure cause the molecules of the rocks to realign themselves and the crystals of the room change causing the rock to metamorphose into a different rock.

2. The answer is; magma

Apart from the heat that is associated with the enormous pressure in the great depths of the earth crust due to the weight of overlying rock layers, magma in magma chambers in the crust also part of the intense heat in these regions. This heat changes rocks into metamorphic rocks.  

3. The answer is; foliated

The pressure and temperatures in the earth's crust are not uniform. A part of rock may be subjected to a slightly higher temperature and pressure compared to another region of the rocks. This unevenness causes different crystal structures and orientations at different points in the rocks making the rock appear layered or banded.

The complete question

What is meant by the statement "every metamorphic rock has a parent rock"? view available hint(s)

a) all metamorphic rocks are created only through the change of preexisting rock.

b) all metamorphic rocks form from the cooling of previously melted rock.

c) metamorphic rocks share no similarities with the original material from which they formed.

d) all metamorphic rocks are created only from previous metamorphic rocks.

e) all metamorphic rocks are created only through accumulation of pieces of previously existing rocks.

Every metamorphic rock has a parent rock

All metamorphic rocks are formed from preexisting rocks. The parents rocks might be sedimentary, igneous or even metamorphic. The parent rocks undergo deep burial where heat and pressure act on it to form metamorphic rock. The new rock may change in mineral assemblage or texture. The transformation usually takes place in the solid state. Example is the transformation of limestone to marble. Marble is a metamorphic rock.

Explanation:

a) all metamorphic rocks are created only through the change of preexisting rock.

All metamorphic rocks are formed from preexisting rocks. The rock might be sedimentary, igneous or even metamorphic rocks. The rock are changed by the process known as metamorphism. The changes occur during burial of the parent rocks where pressure and heat act on it.

b) all metamorphic rocks form from the cooling of previously melted rock.

Not all metamorphic rock are usually formed from the cooling of previously melted rocks. For examples igneous rocks are formed from the solidification of magma. The rocks where once semi liquid before it solidified to form igneous rocks. Metamorphic rocks are formed from these igneous rocks through cooling, the pressure that act on the parents rocks are not enough to melt it. The transformation to metamorphic rocks takes place in the solid state.

c) metamorphic rocks share no similarities with the original material from which they formed.

Metamorphic rocks are formed through the process of metamorphism. Metamorphism occurs after burial of the parent rocks. Heat and pressure act on the original rocks changing the mineral assemblage , texture or both to form a new kind of metamorphic rock. The new rock formed  might be different from the original rock in texture or mineral assemblage. This new rocks might end up not sharing any similarities with the original rock. But some metamorphic rocks share great similarities with the original rock.

d) all metamorphic rocks are created only from previous metamorphic rocks.

Metamorphic rocks can be created from previous metamorphic rocks if the pressure and temperature is right to form the new metamorphic rock. Not all metamorphic rocks are created from previously existing metamorphic rocks.

e) all metamorphic rocks are created only through accumulation of pieces of previously existing rocks.

Not all metamorphic rocks are created through the accumulation of pieces of previously existing rocks. But all metamorphic rocks are created from previously existing rocks.

Hey do you still need the answer i have the first one but im still working on the rest im in k12 to xD

1)    *The oldest rock layers of rocks are found on the bottom, well the youngest rocks are found on top. The different colors of these layers are caused by many different minerals and materials and a main two of the main rolls are iron and climate

that is what i have for the first one

To form metamorphic rocks, rocks do not melt but they are still heated up and their mineral structures change. 
"Morph" means to change

It forms from other rock as a result of intense heat, pressure, or chemical processes.
