What is the longest mountain range within Europe?

Timoteo, The term is a portmanteau of the words Europe and Asia. Although the physical combination of Europe and Asia constitutes the geologic Eurasia, the land boundary between those two continents is not universally agreed upon (?) The continents of Europe and Asia, for example, are actually part of a single, enormous piece of land called Eurasia. But linguistically and ethnically, the areas of Asia and Europe are distinct. Because of this, most geographers divide Eurasia into Europe and Asia. (?) Depends on your perspective but you canNOT simply change peoples minds about it

I don't really get why we talk geographically about Europe as a continent separate from Asia. Politically I can understand it but not geographically. It's Eurasia. The Himalayas and the Alps are found in Eurasia.
