What three factors can change a sedimentary into a metamorphic rock?

Answer 1

heat,pressure,&chemically active fluids

Answer 2

The parent rock (sedimentary or igneous) 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. The heat and/or pressure can transform the minerals inside the parent rock to new minerals, cause recrystallization of existing minerals, cause a chemical transfer of material through fluids, or reorganize the existing minerals into bands and layers. All of these processes take place without any melting of the parent rock.

Answer 3

A metamorphic rock can be changed into:

1. another metamorphic rock by a new temperature/pressure environment.
2. can be broken down by the forces of weathering and erosion at the surface.
3. can be broken down by chemically active groundwaters.

Answer 4

both temperature, pressure and fluid (PTX).

Answer 5

Temperature, Pressure and Fluids, such as Magmatic Fluids.

Answer 6

Heat, pressure, and temperature
