Different soil types develop in different climates. Soils-4-8 Image: Image: T. Loynachan
United States Department of Agriculture Soils are very different, depending on how they form
Prairie soils have a dark surface layer (horizon), are rich in minerals, and form in grasslands widespread across Earth’s middle latitudes. Soils-4-2 Images: NRCS
Forest soils have a light gray upper horizon, a horizon rich in aluminum and/or iron, and form in warm to cool humid regions where coniferous forests grow. Soils-4-3 Image: Bruce Molnia Image: Soil Classifiers of Michigan
Tropical soils are reddish and iron-oxide rich, depleted in nutrients, and form in humid and warm regions. Soils-4-4 Images: National Cooperative Soil Survey, University of Nebraska
Organic soils are dark colored, rich in decomposed organic matter, and form in poorly drained lowlands such as swamps and wetlands. Soils-4-5 Images: Bruce Molnia, Soil Classifiers of Michigan
Desert soils form in arid settings and are commonly rich in calcium carbonate. Soils-4-6 Images: Martin Miller, NRCS
Tundra soils form in Arctic environments, have a dark organic-rich upper layer, and a mineral rich layer over frozen ground. Soils-4-7 Images: Travis Hudson, Alaska/Yukon Society of Professional Soil Scientists

Berdasarkan konvensi Ramsar Lahan basah” mencakup ekosistem yang lebih luas daripada yang dipahami oleh masyarakat umum. Pasal 1.1 dari Konvensi Ramsar menetapkan bahwa lahan basah adalah “daerah paya, rawa, lahan gambut atau perairan, baik alami maupun buatan, permanen atau sementara, dengan air yang diam atau mengalir, segar, payau atau asin, termasuk daerah perairan laut dengan kedalaman pada saat surut tidak melebihi enam meter”.
