Physical Weathering: Among the most commonly found tangible weathering examples are ice wedging, growing of plant roots in rock cracks. As interesting as these types of weathering is, one example would be that of lichens that are found in rocks, causing it to open and be more vulnerable to weathering. Some prominent chemical weathering examples would include oxidation, the salinity of seawater, etc.īiological Weathering: When the mineral weathering is started or accelerated by the microorganisms present in the soil, it is called biological weathering. Oxidation, the salinity of seawater are some of the prominent examples of chemical weathering. The main agent of mechanical weathering is the water, either in liquid form or in solid form.Ĭhemical Weathering: The type of weathering, that causes the molecular structure of the rocks and soil to change, is called chemical weathering. Mechanical Weathering: Mechanical weathering is also regarded as physical weathering. Below you can find further detail about these types. There are mainly three types of weathering, which are Mechanical Weathering, Chemical weathering, and Biological Weathering. There are Primarily Three Different Types of Weathering Processes: Often confused with erosion that occurs with the movement of rocks, soil, minerals via water, gravity, snow, wind, weathering, on the other hand, only occurs in rocks, soil, and minerals that stay in one place. The causes of weathering can be the effect of continuous biological, chemical, and physical processes, as seen on rocks, wood, soils, and minerals. Such a process, in its elaborate form, is called weathering. Be it because of rains, snow, wind, or sunshine, the rocks break down or disintegrate into smaller units. The rocks are harmed by these processes’ repeated action.Several naturally-occurring processes influence the world that we see around us, and that's why the terrain and the sea are diverse. Physical weathering is caused by applied forces, such as water pressure, thermal expansion forces, and gravity forces. Very rarely does any one of these processes operate independently. Weathering is classified into three types:Īll three processes are together found to be in operation. Weathering is a complex process dependent on factors like climatic, topographic, and vegetative factors. Weathering helps form minerals and soil formation, which encourages agriculture and human settlements. Weathering derives energy from insolation guided by the surface of the Earth, including the atmosphere. As minimum material movement occurs in the weathering phenomenon, it can be called the in-situ weathering process. The surface and subsurface rocks break up, dissolve and decompose to disintegrate into fragment materials. Weathering is the primary stage of denudation. The weather and climatic factors can either act individually or collectively to break the surface materials into fragments (disintegration). temperature and rainfall) over Earth materials. Weathering can be defined in simple terms as the action of weather and climatic factors (e.g. Difference Between Weathering and Erosion.UPPSC RO ARO Previous Year Question Papers.UPSC Geo Scientist Eligibility Criteria.UPSC EPFO Previous Year Question Papers.
