How are metamorphic rock formed?

Answer 1

Metamorphic rocks are formed from a protolith, or parent rock, which can be of any rock type (igneous, sedimentary, or metamorphic). The parent rock is exposed to varying degrees of pressure and/or heat either from depth of burial, exposure to a plutonic body of intense heat, or from pressures resulting from the collision of tectonic plates. Exchanges of elements can also occur from hot fluids associated with plutonic intrusions.The heat and/or pressure can transform the minerals inside the parent rock to new minerals, cause recrystallization of existing minerals, or reorganize the existing minerals into bands and layers. All of these processes take place without any melting of the parent rock.

Answer 3

Weathered products of existing rocks are transported , deposited , compacted , and cemented.

Answer 4

they are formed by pre-existing rocks in a solid heat pressure or chemical activity

Answer 5

metamorphic is new rock that forms when existing rock is heated or squeezed.

Answer 6

Metamorphic rocks form when igneous or sedimentary (or even a metamorphic rock) are put under immense heat and pressure.
