Erosion
Strips away loosened clasts and transports via gravity, glaciers, flowing water, or wind
Transport
Movement of sediment away from source, by water, wind, or ice
Rounding
By abrasion
Sorting
Separated by grain size
- Size decreases with distance transported

Clastic
Cemented grains or clasts of other rocks
Intrusive and Extrusive
Felsic, Intermediate, Mafic, Ultramafic
Sedimentary Rock Classes
