Mountain formation

Episode 5 of Plate Tectonics focuses on orogeny, the process of mountain formation. Building upon our knowledge of plate tectonics, continental drift, seafloor spreading, and subduction, we will explore the different types of mountain ranges and how they form. We will delve into the forces involved in mountain building, including compression, uplift, and faulting. This episode will also cover the relationship between mountain formation and other geological phenomena, such as earthquakes and volcanism. Understanding orogeny is key to comprehending the dynamic evolution of Earth's surface.
