Overview of Geologic Structures Part 1: Rock Deformation, Stress and Strain

The video tutorial covers the geologic time scale, focusing on the four eons: Haitian, Archaean, Proterozoic, and Phanerozoic. It explains how rocks deform over time due to mechanical properties and environmental conditions like pressure and temperature. The concepts of stress and strain are introduced, along with Young's modulus, which describes material response to stress. The tutorial also discusses rock competence and the four deformation mechanisms: brittle, elastic, plastic, and viscous. Finally, it explores the causes of earthquakes and the role of plastic deformation in the Earth's crust and mantle.
