And don't forget Hawaii has mountain ranges as the question refers to USA, not just North America.

To find a comprehensive list of mountain ranges in the USA, you can start by visiting Wikipedia.org. In the search bar, type "list of mountain ranges in North America" and click on the corresponding page. Once you're on the page, you can scroll down until you find the section specifically about mountain ranges in the United States.
You will find a list that includes the Rockies, Sierra Nevada, Cascades, and Appalachians, which you have already mentioned. Additionally, there are other mountain ranges such as the Alaska Range, Coast Ranges, White Mountains, and many more. It's important to note that even though these mountain ranges are primarily located in the United States, some may extend into adjacent countries.
Lastly, it's important not to forget about the Hawaiian Islands, which contain several mountain ranges, like Mauna Kea and Mauna Loa. While Hawaii is not located on the continental United States, it is still a part of the United States.
