How many years can a mountain exist before it's washed into the ocean?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

The ages of some mountain ranges include 50-100 million years for the Rocky Mountains (still tall and jagged), about 480 million years for the Appalachians (low and rolling), and over 3 billion years for the Barberton greenstone belt in South Africa.
