GLY 2010C Lecture Notes - Lecture 14: Soil Horizon, Aluminium Oxide, Regolith
Document Summary
Distinct zones within a soil, distinguished from each other by factors such as chemical composition and organic content. (page 195) Sediment that has undergone changes at the surface of the earth, including reaction with rainwater and the addition of organic material. (page 195) The layer of regolith in which water dissolves ions and picks up very fine clay; these materials are then carried downward by infiltrating water. (page 195) The top soil horizons, which are typically dark and nutrient-rich. (page 196) A type of soil consisting of roughly equal parts of sand, silt, and clay; it tends to be good for growth of crops. (page 197) A hard, brick-red, soil formed from iron-rich rock in a tropical environment; it consists primarily of insoluble iron and aluminum oxide and hydroxide and forms due to extreme leaching. (page 199) The removal of soil by wind and runoff. (page 199)
