The rupture of rocks by physical or chemical processes at their place is called weathering. Weathering is a static process because it does not involve the transport of broken materials of rocks. Erosion involves the actions of transport. Thus weathering is a static action while erosion is a dynamic action. The addition of weathering and erosion is denudation, which involves both actions (static and dynamic). All physical and chemical characteristics of rocks are included in the structure such as hardness and mineral composition of rocks. The physical properties and mineral composition of rocks determine how they will be affected by weathering. For example, the process of chemical weathering in rocks with porous and soluble minerals is rapid. Let's know more about Weathering And Erosion.
