Insitu theory and drift theory are related to the____________________?
Correct answer: A. Origin of coal
- A. Origin of coal
- B. Origin of petroleum oil
- C. Coalification
- D. Variation of coal quality with depth
Explanation
In-situ theory proposes that coal formed where the original plant material grew, whereas drift theory proposes transport and deposition before burial. Both theories therefore explain the origin of coal.
