Why Some Minerals Only Occur In Metamorphic Rocks.?
because if the metamorphic rocks are big they will shrink
Why do some minerals only occur in metamorphic rocks?
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.
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.
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.
What do metamorphic sedimentary and igneous rock have in common?

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.
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
Do metamorphic rocks have holes?
only on wednesdays
