WebJun 10, 2024 · The higher the degree of weathering and the longer the water–rock reaction time, the more favorable the dissolution and enrichment of Sr in groundwater. Moreover, the large weathering thickness and fracture development of the rocks in the Tianjiazhai area provide favorable conditions for the formation of Sr-rich groundwater. WebWeathering is the breakdown or loosening of surface minerals of rocks after exposure to weathering agents such as water, oxygen (air), organic and inorganic chemicals, and temperature. Weathering occurs in place (in situ). Weathering is the event that comes before the action of erosion.

How does rocks undergo weathering

WebRocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. In this activity, you will model how abrasion works. Web1. The longer a rock is exposed to the agents of weathering, the greater the degree of alteration, dissolution and physical breakup.
