Metamorphism is the name of the process (of heat and pressure) that causes the chemical; and therefore mineralogical; properties of a rock to change. Marble (changed from limestone) may represent the lowest grade of metamorphism, whilst the schists are a more common higher grade of that same process. At the extreme, the rocks will melt, but that is considered beyond the definition of metamorphism, for it will change the actual chemical nature of the rock. So - it is the application of heat and pressure; perhaps accompanied by shear; that are the metamorphic change agents. Usually caused by deep burial.

What is the only kind of rock that can form directly from magma?
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
How does the metamorphic rock change into a igneous rock?
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
What causes waves in the rock layers?
depending on the rock. sedimentary rocks are formed under water and may have water wave ripples. metamorphic rock has been pressed into waves. igneous rocks flowed in waves
How does a garnet form?
Garnets are formed inside metamorphic rock, which is rock that has been changed by some force. This force also helps to form the garnet, and usually involves heat or pressure.
What type of rock always forms directly from another rock?
Metamorphic. By contrast, igneous rocks form from lava or magma, and sedimentary rock form from sediment. Those things are formed from previous rocks, but constitute intermediate stages: igneous and sedimentary rocks are formed indirectly from previous rocks.
What type of rock was the metamorphic rock schist formed from?
Probably the metamorphic rock phyllite.
Type of rock formed by heating and squeezing other rocks?
metamorphic.
How can a rock be transformed into a metamorphic rock?
Rock can be changed into metamorphic rock by heat and pressure.
What kind of rock does a metamorphic rock start as?
Metamorphic rocks are formed from sedimentary rocks.
Is slate a metamorphic rock which transforms from shale?
Slate is a metamorphic rock formed from the parent rock shale.
What rock can be formed uplifted metamorphic rock?
Dick
What metamorphic rocks are formed from mudstones?
Slate,schist,gneiss are the metamorphic rock formed from mudstone.
What is a metamorphic rock formed from a shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Are metamorphic rock only made out of from igneous?
No, metamorphic can be formed by either igneous or sedimetary rock.
Is slate a foliated metamorphic rock?
Yes, slate is a foliated metamorphic rock formed from the sedimentary rock shale.
Can sedimentary rock be turned into metamorphic rock?
Yes it can, a sedimentary rock goes through heat and pressure and is formed into a metamorphic rock.
What is metamorphic rock forms from?
Metamorphic rock is formed when Igneous rock and Sedimentary rock go through intense heat and pressure.
