Question: How do temperature and pressure affect the metamorphic rock formation
(5 points)
If the rocks are buried deep, temperature and pressure will get increased.
Contact metamorphism creates no-foliated metamorphic rocks.
Magma will bake the surrounding rocks due to difference in temperature.
Deformed rocks with foliation/lineation is brought by pressure and
recrystallization of minerals.
Pressure is the main factor of contact metamorphism
Slate and gneiss are examples of foliated rocks.

Answer:
Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.
Explanation:
Metamorphic rocks are rocks that have undergone a transformation.
Metamorphic rocks began as another kind of rock, but have undergone significant transformations from their initial igneous, sedimentary, or metamorphic state. When rocks are exposed to intense heat, high pressure, hot mineral-rich fluids, or a combination of these conditions, metamorphic rocks occur. These kinds of conditions can be found deep beneath the Earth or when tectonic plates collide.
Metamorphism: Metamorphism is a process that changes rocks into denser, more compact rocks rather than melting them. Rearrangement of mineral components or interactions with fluids that penetrate the rocks produce new minerals. Even previously metamorphosed rocks can transform into new kinds due to pressure or temperature. Squished, smeared, and crumpled metamorphic rocks are common. Despite these unpleasant circumstances, metamorphic rocks do not melt, otherwise they would turn into igneous rocks.
