Question

Select the correct statement from the given:

• A. Peat is the most abundant rank of coal
• B. Peat has a heating value between 8300 and 13000 British Thermal Units per pound on a mineral-matter-free basis.
• C. Peat is an organic sediment.
• D. Peat has a carbon content of between 60 and 70%

Answer 1

Answer: (C)

Peat is an organic sediment.

The rank of coal is based on the degree to which the original plant material has been transformed into carbon.

The ranks are as follows:

(i) Anthracite (ii) Bituminous coal (iii) Sub-bituminous coal (iv) Lignite

Peat is mainly composed of wetland vegetation. Therefore, principally bog plants including mosses, sedges and shrubs. So, it is organic sediment.
