What type of material is peat primarily made from?

Wood
Coal
Moss
Sand

The correct answer is: Moss

Peat is primarily made from partially decayed plant material, particularly moss. This accumulation occurs in waterlogged conditions where the decomposition of organic material is slowed down due to the lack of oxygen. Sphagnum moss is the most common type found in peatlands, and as it dies, it accumulates and forms layers that contribute to peat formation over thousands of years. The unique anaerobic environment preserves the organic matter, which is why peat is rich in carbon and is considered an important carbon sink. This characteristic makes peat distinct from materials such as wood, coal, or sand, which do not have the same composition or formation process.
