Question

Quizplus · Accepted Answer

Geologists believe that when the thick and high part of a mountain belt becomes too high and gravitationally unstable, gravitational collapse and spreading occurs. This is known as a process called mountain building orogenesis. Massive landslides may occur as a result of this process, but they are not the primary mechanism for the mountain belt collapse. Volcanic eruptions, rapid downcutting, and basalt flows are also not typically associated with this process.
