Why aren't metamorphic rocks 'unmetamorphosed' as temperatures drop?

Metamorphic rocks are created when compressed at high temperatures, as temperatures drop, they just start to solidify more, instead of becoming liquid again.
A similar process is drying clay, as the clay dries, it becomes harder.

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.

Why Doesn't metamorphic rock occur at temperatures 1000 degrees or higher?
if rock melts it will form magma, which leads to the formation of igneous rocks
What rocks are formed by the effect of heat and pressure on other rocks?
the metamorphic rocks are formed by heat and extreme pressure from other rocks
How can mudstone be changed into a metamorphic rock?
It can be buried, and huge pressures and temperatures can change them into metamorphic rocks.
What rocks are formed from high temperature and pressures?
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.
Which metamorphic rocks are most likely to have formed the highest temperatures and pressures?
Gneiss is a metamorphic rock that meets those criteria.
Which metamorphic rocks are most likely to have formed at the highest temperatures and pressure?
Gneiss is a metamorphic rock that meets those criteria.
What type of rock do heat and pressure make?
Metamorphic rocks are created when existing solid rocks are exposed to high temperatures and pressures.
What rocks are changed by high tempatures and high pressure?
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.

Where or under what settings would a metamorphic rock most likely form?
Metamorphic rocks are formed beneath the Earth's surface It changes into Igneous rocks through extremely high temperatures and intense pressure.
Which metamorphic rocks form under high stress and low to moderate temperatures in subduction zones?
Blueschist
Which type of rocks are produced from other type of rocks under high temperature and pressure?
Metamorphic rock can result from the exposure of existing igneous, metamorphic, and sedimentary rock to high temperatures, high pressure, or a combination of both.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Are unakite rocks Sedimentary rocks Metamorphic rocks or Igneous rocks?
metamorphic
