| Feature | Himalayas | Andes |
|---|---|---|
| Location | Asia | South America |
| Height | Highest in the world (e.g., Mount Everest) | Very high, but generally lower than Himalayas |
| Length | Approx. 2,400 km | Approx. 7,000 km (longest continental range) |
| Formation | Collision of Indian and Eurasian plates | Subduction of Nazca and Antarctic plates beneath the South American plate |
| Key Peaks | Mount Everest, K2, Kangchenjunga | Aconcagua, Ojos del Salado |
| Climate | Varies from subtropical to arctic | Varies from tropical to alpine desert |
Similarities: Both are major young fold mountain ranges formed by tectonic plate collisions, featuring high altitudes, significant biodiversity, and geological activity.
Differences: The Himalayas are higher and shorter, formed by continental-continental collision, while the Andes are longer, formed by oceanic-continental subduction.
