Question
Coal is formed in which of the following depositional environments?
A. A river channel
B. A glacier
C. A swamp
D. A beach
Solution
Coal is formed in C. A swamp.
Here's the step by step process:
-
Coal begins to form when plants in a swampy area die and fall into the water.
-
Over time, more and more plant material accumulates and is buried under mud and water.
-
As the plant material is buried deeper and deeper, it experiences more and more heat and pressure.
-
This heat and pressure transforms the plant material into peat, then into lignite, then into bituminous coal, and finally into anthracite coal.
So, the correct answer is C. A swamp.
