Soil order (type) of the United States Natural Resources Conservation Service Soil Classification System.
These soils have horizons in the early stages of pedogenesis.
This process continues for many cycles until the ice wedge reaches its maximum size.
Deposition of humus, chemical substances, and fine mineral particles in the lower layers of a soil from upper layers because of the downward movement of water through the soil profile. Species that migrate into an ecosystem or that are deliberately or accidentally introduced into an ecosystem by humans.
Some of these species are beneficial, whereas others can take over and eliminate many native species.
Compare with indicator species, keystone species, and native species.
Inference of a generalized conclusion from particular instances.
Many of these soils are found on glacial drift deposits.
Contour line that is accentuated in thickness and is often labeled with the appropriate measure of elevation.
