Question

Which quality of coal is generally found in the Gondwana coal reserves?

Mention two uses of coal.

Name two states in India which have huge deposits of Gondwana coal.

What are tertiary coal fields?

Answer 1

Bituminous coal is found in Gondwana coal reserves
Uses of Coal
1)The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Steam coal - also known as thermal coal - is mainly used in power generation. Coking coal - also known as metallurgical coal - is mainly used in steel production.
2)It is used as a fuel
Tertiary Coal Field
The Gondwana coal is mainly bituminous or anthracite in which the carbon content varies between 60 to 90 per cent. The bituminous coal is converted into coke before being used in the iron and steel industry..TERTIARY COAL. Tertiary coal is found in the rocks of the Oligocene period of the Tertiary Era

Answer 2

• Bituminous coal is generally found in the Gondwana coal reserves. Bituminous has 60-80% of carbon in it.
• Two uses of coal- 1. Thermal electricity: heat is obtained from coal, especially substandard varieties such as lignite and brown coal.

                                     2. Fossil fuel: coal is a fossil fuel. It is used a fuel in various household and economic works.

• Jharkhand and Odisha have huge deposits of bituminous coal in India.
• Tertiary coal fields are almost 15 to 60 million years old, formed during the Tertiary Era. The coal here is called brown coal which has very low percentage of carbon content.
