Geological Processes and Faults

The video tutorial covers rock deformation, focusing on faults and folds. It explains fault types, including normal, reverse, and strike-slip faults, and their formation processes. The concept of isostatic adjustment and subsidence is discussed, highlighting their role in geological formations. Folding processes and their classifications, such as synforms and anticlines, are detailed. The video also explores metamorphism, rock cleavage, and the formation of metamorphic rocks like gneiss, blueschist, and greenschist.
