Question

what is meant by lignite​

Answer 1

Answer:

A soft brownish coal showing traces of plant structures, intermediate between bituminous coal and peat.

Answer 2

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent.  One of the main elements in Restore is the lignite extract. Lignite comes from decomposed prehistoric matter. As plants decay, they first form peat, which then turns into humate, then lignite, then leonardite and finally to coal. All of these are rich in carbon.
