TOP SOIL= Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.
ELUVIATED =Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.
SUBSOIL= Rich in minerals that leached .
BEDROCK=A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.
