Weathering

Science / Geology / Weathering: The set of all processes that decay and break up bedrock, by a combination of physically fracturing or chemical decomposition.

Mechanical Weathering

Science / Geology / Mechanical Weathering: A general term applied to a variety of weathering processes that result in the particle size reduction of rock materials with no change in composition. Frost action, salt crystal growth and pressure r MORE

Zone Of Weathering

Science / Geology / Zone Of Weathering: A subsurface area, above the water table, where mineral and organic materials are subject to weathering. MORE

Chemical Weathering

Science / Geology / Chemical Weathering: The breaking down of surface rock material by solution or chemical alteration. Common alteration processes are oxidation and hydrolysis. MORE

Shale

Science / Geology / Shale: a clastic sedimentary rock that is made up of clay-size (less then 1/256 millimeter in diameter) weathering debris. It typically breaks into thin flat pieces. Picture of Shale. MORE

Karst

Science / Geology / Karst: A landscape that is characterized by the features of solution weathering and erosion in the subsurface. These features include caves, sinkholes, disappearing streams and subsurface drainage. MORE
