The Brooks Range in Alaska is a result of plate tectonics:
* Collision: The Brooks Range formed due to the collision between the North American Plate and the Pacific Plate.
* Subduction: The Pacific Plate is subducting (diving) beneath the North American Plate. This process causes the North American Plate to buckle and fold, creating the Brooks Range.
* Uplift: The collision also causes uplift, pushing the mountains upwards.
* Erosion: Over millions of years, erosion by wind, water, and glaciers has shaped the Brooks Range into its current form.
The Brooks Range is a relatively young mountain range, having formed in the Cenozoic Era (the last 66 million years).
