As the plants grew, some died and fell into the swamp waters. … The weight of the top layers and the water and dirt packed down the lower layers of plant matter.

Why swampy areas are ideal places where coal can form?

The formation of coal begins in areas of swampy wetlands where groundwater is near or slightly above the topsoil. Because of this, the flora present produces organic matter quickly – faster in fact than it can be decomposed. … It is these layers of organic material that then form coal.
