Coal is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers called coal beds

Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time

5 Formation

5.1 Formation

Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal.

Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
