Answer:

Match List I(Original Rock) with List II(Metamorphic Rock) and select the correct answer using the code given below:

List I(Original Rock)

List II(Metamorphic Rock)

(A) Granite (I) Diamond

(B) Coal (II) Marble

(C) Limestone (III) Slate

(D) Shale (IV) Gneisis

Slate

Slate is a low-grade and fine-grained metamorphic rock that can be separated into thin pieces. It is a type of foliated metamorphic rock that is produced by the metamorphism of shale. Slates are predominantly realigned clay minerals.

Marble

Marble is among the non-foliated metamorphic rocks produced from the metamorphism of dolostone or limestone. It takes high polish and is often used for sculpture and as building material. Marble is mainly composed of calcium carbonate

Gneiss

Gneiss is a foliated metamorphic rock made up of granular mineral grains. It contains a lot of feldspar minerals and bands of quartz and sometimes mica. It normally has a banded appearance and is sort of laminated. It appears similar to granite.

Diamond

When the plants die, they decay and turn into peat. Then the peat can eventually turn into a sedimentary rock called coal (which is entirely made of carbon atoms). Finally, if the coal is under pressure, it can become the metamorphic rock graphite (also made of carbon atoms, but they’re arranged in a different way). Carbon can also metamorphose into diamonds.

So option D is correct.
