tectonism
Planetary crust movement
Tectonism is the process by which the Earth's crust deforms, folds, and fractures due to forces within the planet.
It encompasses the large-scale movements that build mountains, create rift valleys, and shift continents.
Geologists study tectonism to understand earthquakes, volcanic activity, and the formation of major landforms over millions of years.
