Why are the Rocky Mountains taller and sharper than the Appalachian Mountains in north America?

Answer 1

The Rockies and the Appalachians are similar geologically (although the Appalachians are a little more diverse) however the Appalachians were emplaced a lot longer ago and have been exposed at the surface longer and therefore are more eroded down. By contrast the Rockies are still quite young (they were pushed up roughly in the Cretaceous, probably 100-200 million years after the Appalachians) and haven't been weathered down very much yet.

Answer 2

The simpilest answer is age. The Appalachian Mountains are much older than the Rockies, as Mountains age, the wind, sand, rain, and other weather gradually (over millennia) wear down the Mountains.
