Major Mountain Ranges:
* The Himalayas: This massive mountain range, home to Mount Everest, formed due to the collision of the Indian and Eurasian tectonic plates. The collision began in the Cenozoic and is still ongoing, leading to continuous uplift.
* The Alps: Located in Europe, the Alps formed from the collision of the African and Eurasian tectonic plates. This collision, which began in the Late Cretaceous, continued through the Cenozoic, creating the towering peaks we see today.
* The Andes Mountains: Stretching along the western coast of South America, the Andes are the longest mountain range in the world. They were formed by the subduction of the Nazca Plate under the South American Plate, a process that began in the Cenozoic.
* The Rocky Mountains: Found in North America, the Rockies were formed by the compression and uplift of the North American Plate, driven by the subduction of the Farallon Plate. This process occurred mainly during the Laramide Orogeny, which spanned the Late Cretaceous and the Paleocene epochs of the Cenozoic.
* The Sierra Nevada Mountains: Located in California, the Sierra Nevada range is a result of the subduction of the Farallon Plate under the North American Plate. The uplift of the mountains occurred in the Cenozoic, with much of the shaping of the Sierra Nevada's iconic granite peaks occurring during the Pleistocene epoch (about 2.6 million to 11,700 years ago).
Other Notable Mountain Ranges:
* The Appalachian Mountains: While the initial formation of the Appalachians occurred much earlier, the mountains were significantly uplifted during the Cenozoic due to the collision of the African and North American plates.
* The Caucasus Mountains: Located between the Black and Caspian Seas, the Caucasus Mountains were formed by the collision of the Arabian and Eurasian plates. This collision began in the Cenozoic and is still ongoing.
* The Pyrenees Mountains: Situated on the border of France and Spain, the Pyrenees were formed by the collision of the Iberian and Eurasian plates. The uplift of the Pyrenees occurred during the Cenozoic, reaching its peak during the Oligocene epoch.
It's important to note that this list is not exhaustive. Many smaller mountain ranges and mountain chains also formed during the Cenozoic, and their formation is often tied to the ongoing movement and interaction of Earth's tectonic plates.
