Question

Drag each tile to the correct box. Arrange the events involved in the formation of coal in the order they occurred.

A) Peat formation, Lignite formation, Bituminous coal formation, Anthracite coal formation
B) Lignite formation, Peat formation, Bituminous coal formation, Anthracite coal formation
C) Peat formation, Anthracite coal formation, Lignite formation, Bituminous coal formation
D) Bituminous coal formation, Anthracite coal formation, Lignite formation, Peat formation

Answer 1

The events involved in the formation of coal occur in the order of Peat, Lignite, Bituminous, and then Anthracite. This sequence reflects the increasing grade and energy content of the coal with time and pressure.

Step-by-step explanation:

The correct order of the events involved in the formation of coal is Peat formation, Lignite formation, Bituminous coal formation, and finally Anthracite coal formation. This sequential transformation occurs due to the burial of plants under sediment, where they are subjected to high temperatures and pressures over millions of years, beginning with peat and ending with high-grade anthracite. As we move from using Anthracite to Lignite coal, more mass of coal would need to be mined to achieve the same energy output, due to Lignite's lower energy content.
