Geological Processes and Natural Disasters

The video explores Earth's structure, starting with its layers: core, mantle, and crust. It introduces Alfred Wegener's continental drift theory and its initial rejection. Harry Hess's work during WWII, using sonar, led to the development of plate tectonics theory. The video explains plate movements: divergence, convergence, and transform, and their role in forming landforms. It covers earthquakes, their causes, and the Richter scale. Tsunamis and hot spots, like those forming Hawaii and Yellowstone, are discussed. The video concludes by linking these geological processes to the creation of mountains like Everest.
