Peat layer (black) over bedrock in a cliff. Peat is of organic origin,comprising plant debris that decomposed in anaerobic (airless) conditions,such as in a waterlogged area like a marsh. Peat can be used as a fuel and as a fertiliser. Photographed near Quito,Ecuador,at an altitude of 3800-4000 metres on the paramo,a region of high-altitude grasslands in the Andes mountains | |
