Wind, Water, Gravity, Glaciers
The top most soil horizon that is filled with organic living and dead material.
Horizon O
The change in the physical form or chemical composition of rock materials exposed at the earth’s surface
Weathering
chemical weathering that involves an acid base reaction between the mineral and CO2 in the water.
Carbonation
Type of mechanical weathering that involves water or wind or other materials hitting against a piece of rock.
Abrasion
Things like rockfalls and mudslides are examples of these.
