An area of rock deformation caused at plate boundaries where there is extreme pressure and heat.
In comparison to Contact metamorphism where existing rock undergoes neocrystalization because of extreme heat from being in close proximity to lava.
Regional metamorphism
The two groups of metamorphic rock are foliated and nonfoliated. Metamorphic rocks can also be classified as contact and regional.
regional metamorphism
it is formed by high-grade regional metamorphic processes
regional and contact
True
Regional

Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
uh, i think you mean 'metamorphic'....
yes, slate is metamorphic rock
contact metamorphism is what happens when something is really hot. regional metamorphism on the other hand involves much larger packages of rocks.
