The video tutorial explains mass wasting, a process driven by gravity that causes sediment and debris to move downhill. It covers rapid events like landslides and rockslides, which can cause significant destruction, and slower processes like creep. The tutorial also highlights mud flows, using a 1996 Iceland event as an example, where a volcanic eruption under a glacier led to a massive flow of water, mud, ice, and rock. The video emphasizes the potential threats these natural processes pose to life and infrastructure.
