Uplift refers to the vertical elevation of the Earth’s surface due to tectonic forces, such as those caused by plate collisions, volcanic activity, or the rebound following the melting of ice sheets. Uplift is significant in geology for understanding mountain building, landscape evolution, and the interaction between tectonics and erosion.
