This annotated slide set shows how the introduction of rain water changes the elemental composition of parent material as it is weathered into first immature and then mature soil.
The site illustrates and explains the chemical weathering of aluminum, iron, silicon, calcium, magnesium, sodium, and potassium minerals under minimal, moderate, and intensive weathering conditions. Captions also explain in which climates each type of weathering occurs.
