Describe what needs to occur in order for a metamorphic rock to form.
katovenus [111]

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under <u>extreme pressure</u> or <u>extreme heat</u><u>.</u> and there are two types of metamorphic rocks, <u>contact</u> <u>metamorphism</u> and <u>regional metamorphism</u><u>.</u>

Those mean pretty much exactly what they say.

If you have any more questions, ask, but i think I covered the most important parts of the answer.

best of luck
