As the degree of hydration decreases in a rock undergoing metamorphosis, certain minerals cannot exist. New minerals then form that do not require water for their formation. This environment of heat, pressure, and lack of water is necessary for the formation of certain minerals.

Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
What do Metamorphic and Sedimentary rocks have in common?
It is more likely that igneous and metamorphic, or igneous and sedimentary rocks would have something in common than sedimentary and metamorphic. The reason is because the processes involved in making metamorphic rocks is completely different than the processes needed to make sedimentary rocks. Only high temperature, high pressure minerals such as olivine, pyroxene, amphibole can withstand these kinds of conditions. Take quartz and feldspar, two of the most abundant minerals found in sedimentary rocks, these minerals would not be found in abundance in metamorphic rocks because they are not high temperature, high pressure rocks. But the most simple answer is that all the major groups of rocks are made of minerals. Metamorphic has high pressure and Igneous does to and both made from a particle called magma.
Are metamorphic rocks forms only by igneous rocks?
despite what most people think, metamorphic rocks are not formed only by igneous rocks. an example is slate, which forms from shale, a sedimentary rock
What happen to minerals when rocks becomes a metamorphic rocks?
Metamorphic rocks are created from rocks that are deformed by tectonic forces and/or are brought to temperature that are much different from those that they were first formed in (usually hotter). The effect of increased temperature is the growth of minerals from others that are no longer stable under the changed pressure and temperature conditions (e.g. diamond is formed from graphite under very high pressure and garnet growths at high temperatures and pressures from aluminium rich usually sedimentary rocks). The effect of shear stress on the rock (i.e. directed force creating not only compression but also deformation) is the change of shape of minerals as well as rotation and alignment of platy minerals into bands. These processes lead to the usually banded appearance of metamorphic rocks.
Do many metamorphic rocks have fossils in them?
it shows fossils because when sedimentary rocks are formed waste and decayed matter get cement( crushed ) togather. The change of mineral forms metamorphic rocks, but the fossils will remain in the rocks only the minerals will change. eg Limestone ----- marble. Limestone forms marble which is used to build taj mahal.
Why Some Minerals Only Occur In Metamorphic Rocks.?
because if the metamorphic rocks are big they will shrink
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
Why is metamorphic rock hard?
because a metamorphic rock is made up of different rocks.
Do metamorphic rocks have different kinds of minerals from their parent rocks?
Of course they can. The overall compositions of the rocks will remain the same (assuming a closed system, which isn't always the case), but mineralogically there will be changes due to metamorphic pressures and temperatures. There are a whole list of minerals which only formed from metamorphic processes.

Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.

Explain why some minerals only occur in metamorphic rock?
When the rock was forming other minerals that were near the forming place of the metamorphic rock were mixed in after the pressure has been made on the metamorphic rock. I am a seventh grade teacher so I know the answer. We are going over this in class right now.

Do metamorphic rocks have holes?
