Answer:
rapid burial of vast amounts of vegetation
Explanation:
The organic matter is always decomposing, just that it depends on the conditions at what kind of a rate the decomposition will happen. If the climate is warmer and humid, then the decomposition is very quick. This results in a rapid burial of enormous amounts of vegetation. As the vegetation dies out, it piles up constantly, decomposes very quickly, and if there is something that can cover it, like mud for example, it will be buried in the ground. This is actually how the big deposits of coal have got the basis to form in the Carboniferous period.
