This course is a course that discusses exogenous and endogenous forces which are forces that change the face of the earth into a new face of the earth. This course also discusses the structure of the earth as a result of endogenous forces and geological time, fossils, and geological laws in order to deepen understanding of the layering field. The discussion in more detail is the weathering processes, followed by erosion and deposition carried out by water, wind or snow/ice/glaciers which will continuously form a new surface of the earth. Furthermore, the new earth face that is formed simultaneously or in the following period will be damaged by tectonic, volcanic and seismic forces to form another new earth face, which is the next discussion. Discussion about unconformities, faults, folds or cracks in the earth, which are earth structures formed due to destructive (endogenous) forces, is the next discussion. In studying these topics, the use of information technology (IT) is very helpful in making mastery easier and is used to convey information from analysis results. Achievement of learning competencies by using a project based learning approach with inquiry, discussion, question and answer, assignment methods. Assessment is carried out by performance and written tests.
