What type of stress created the Sierra Nevada mountain range?

The Sierra Nevada mountain range was primarily formed through a combination of tectonic forces, specifically compressional stress associated with the subduction of the Farallon Plate under the North American Plate. This tectonic activity led to the uplift of the Sierra Nevada as well as extensive faulting and volcanic activity. Additionally, the region experienced significant erosion from glacial and water activity, which shaped its current rugged topography.
