What are metamorphic rocks?​

Answer 1

Answer:

Quartzite and marble are the most commonly used metamorphic rocks. They are frequently chosen for building materials and artwork. Marble is used for statues and decorative items like vases (Figure). Quartzite is very hard and is often crushed and used in building railroad tracks.

Answer 2

Answer:

Rocks are used for many purposes but some of them that we can see in our daily life are cited below :

Making Cement (Limestone) (Sedimentary Origin)

Writing (Chalk) (Sedimentary Origin)

Building Material (Sandstone) (Sedimentary Origin)

Bath Scrub (Pumice) (Igneous Origin)

Kerb Stone (Granite) (Igneous Origin)

Explanation:

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
