Peat

Blocks of peat for human use

Peat is partly decayed plant material found in layers, usually in marshes.

Peat is composed mainly of the mosses sphagnum and hypnum, but also of sedges, trees, and other plant matter. Under the right geological conditions, peat forms coal. It is used as a mulch and burned as a fuel source for domestic heating.[1]
