Weathering Processes and Factors

The video tutorial introduces the concept of intemperismo, a process of rock degradation influenced by external climatic factors. It explains the three types of intemperismo: physical, chemical, and biological. Physical intemperismo involves mechanical transformations due to temperature and pressure changes. Chemical intemperismo is driven by chemical reactions, primarily involving water. Biological intemperismo results from the influence of living organisms, such as fungi, bacteria, and plant roots. The video concludes with a call to action for viewers to engage with the content.
