Question

Rock like peat , lignite and anthracite called carbonaceous Rock give reason

Answer 1

Rocks like peat, lignite , anthracite are used as fuel materials which are mainly made out of carbon composition (almost 60-90%).

Due to this majority of carbon composition in these rocks, these are known as the carbonaceous rock.
