What two things can cause a rock to become metamorphic rock?

Answer 1

A. Pressure and heat. Both found in the mantle of the Earth.

Answer 2

Heat and pressure are the two main factors that can cause a rock to become metamorphic. When existing rock is subjected to high temperatures and pressures deep underground, its mineral composition and texture can change, resulting in the formation of metamorphic rock.

Answer 3

Heat, such as volcanic activity and extreme pressure such as overburden (metamorphic rocks become changed by being at extreme depths below other rock).

Answer 4

the two things that primarily take place for a rock to be a metamorphic rock is mainly extreme heat, and pressure. when these two collide, you get a meta-morph-ic rock

Answer 5

Heat and pressure.
