Solution:Entisols: Weakly developed soils with no horizons. Entisols lack any other layer except for the A-horizon. They are unaltered from their parents' rock. This is a very diverse group of soils with one thing in common, little profile (horizon) development.
Inceptisols: Soils having weakly or quickly developed horizons. These soils are in the beginning stages of soil profile development. The differences between horizons are just beginning to appear.
Histosols: There soils have a very high quantity of organic matter in the upper layers. Organic matter (20-30%) and are 40 cm thick.
Oxisols: There are highly weathered and old soil with the subsurface horizon being highly oxidised. Key processes include leaching and weathering.
