The weight of the rocks in the crust and upper mantle.
Pressure, Heat, Chemically active fluids (water and CO2 in rocks), Time(obviously), and the parent rock composition.
where do metamorphic rocks form, the mantle crust or core?Metamorphic rocks are rocks that have "morphed" into another kind of rock. These rocks were once igneous or sedimentary rocks. How do sedimentary and igneous rocks change? The rocks are under tons and tons of pressure, which fosters heat build up, and this causes them to change. If you exam metamorphic rock samples closely, you'll discover how flattened some of the grains in the rock are. this is how they are formed.
Igneous rocks form when lava or magma cools.But when cooling there are air bubbles that are trapped in the lava.Prime examples of this event are found in pumice and scoria

Weight causes density, density causes pressure, pressure causes heat. Heat and pressure change rocks into other rocks, which are metamophic.
Sedimentary rock, its rarely found in metamorphic and never found in igneous rock because it would make the fossil of the animal worped and changed. It wouldn't be with the original form on metamorphic and igneous would destroy the whole fossil.
Heat and pressure causes Metamorphic Rocks to form.
The weight of the rocks in the crust and upper mantle.
Erosion is the wearing away of rocks by wind and water, which causes them to break down and form soil.
The weight of the rocks in the crust and upper mantle results in the pressure that allows diamonds to form.

Metamorphic rocks can form from both igneous and sedimentary rocks

No, its erosion that causes rocks to change
