Question

I AM a metamorphic rock either grey or white in colour.I AM used in the construction of buildings and statues.

Answer 1

Answer:

The correct answer can be both marble or sandstone.

Both are metamorphic rocks,i.e. rocks that are generated by the transformation of the existing rock forms caused by heat and pressure changes.

Most sandstones are formed of quartz or feldspar whereas marbles are recrystallized carbonate minerals.

Both are also used for buildings as well as for making statues as they are quite hard and sturdy.

Answer 2

Answer:

• Here I refers to marble which is a metamorphic rock composed of recrystallized carbonate minerals, like calmite, or dolomite.

• Marble is mostly not foliated and are used in the construction of buildings and statues primarily.

• Metamorphic rocks were once igneous or sedimentary rocks, and they can be changed by the pressure and heat.

• In the case of marble, you can find some changes due to pressure and hear because they have crystalline materials and they are porous.
