It seems there might be a typo in your question regarding "as a De range." If you meant to ask about a specific mountain range, such as the "Andes" or "Himalayas," please clarify.
In general, many mountain ranges do cover large areas. For example, the Himalayas in Asia span about 1,500 miles (2,400 kilometers) and include some of the highest peaks in the world, while the Andes in South America stretch over 4,300 miles (7,000 kilometers). Each range has a significant impact on climate, ecology, and human activity in the regions they traverse.
If you can provide the correct name or clarify the specific range you're interested in, I'd be happy to provide more detailed information!
