Definition
Noun: A peat bog is a type of wetland area characterized by wet, spongy ground composed of accumulated layers of partially decayed vegetation, primarily mosses like sphagnum. This environment is acidic and nutrient-poor, with very slow drainage, making the soil unsuitable for agriculture. The accumulated plant material, known as peat, can be cut, dried, and used as fuel.
