All the named rocks are igneous, metamorphic, or sedimentary.
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
metamorphic
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
Metamorphic rocks
It is a type of Metamorphic rock
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.
Sedimentary rocks have layers, not metamorphic rocks.
