Understanding Weathering, Diagenesis, and Sedimentary Rocks
Weathering: Alteration of Surface Rocks
Weathering is the alteration of surface rocks in contact with air and water.
Physics of Weathering
The physical aspect of weathering involves the disintegration or division of rocks into fragments without modifying their chemical and mineralogical composition. Living organisms also play a role.
Gelifraction (Freeze-Thaw)
Gelifraction occurs when water penetrates cracks in rocks, freezes, and expands, increasing its volume and causing fractures.
Haloclastia (Salt
