WEATHERING, EROSION, AND DEPOSITION2Weathering, Erosion, and DepositionWeatheringWeathering refers to the process of disintegration of rocks and minerals present on theearth surface (LaVergne, 2017). There are several agents of weathering. Some of these agents arechange in temperature, animals, plants, salts, acids, ice, and water. There is no rock on the earthsurface that cannot undergo the process of weathering.There are two major types of weathering. These are mechanical and chemical weathering.Mechanical weathering is also referred to as physical weathering. This type of weatheringnormally makes rocks to crumble. Some causes of mechanical weathering are thawing andfreezing (frost action), abrasion, exfoliation, heating and cooling, pressure unloading, andorganism (LaVergne, 2017). Below are figures showing mechanical weathering:Figure 1: Mechanical weathering (Butz, 2018).
WEATHERING, EROSION, AND DEPOSITION3Figure 2: Mechanical weathering (Butz, 2018).In chemical weathering, there occurs a change in the molecular structure of soil or rock.A good case of chemical weathering is where carbon dioxide from the air reacts with water toform carbonic acid during the process of carbonation. The carbonic acid formed dissolves therocks. Once the rocks are dissolved, huge cracks or networks of caves are formed (figure 3).
