What are mountains?

Hey, guys, what's up? I just learned that the oceanic crust is recycled at a subduction zone where one leading edge of convergent lithospheric plates is subducted beneath the other and remelted.  This all means that the crust is melted and made (or formed) again once it is hardened. Other parts of the oceanic crust is formed by volcanos.

Wow, continental crust is composed of materials less dense than oceanic crust so it flows on the mantle rather than being subducted into the athenosphere. The highest mountain range in the world, the snow-capped Himalays, is an example of a continent-to-continent.

K-2 is the second highest mountain in the world, I wish I was the second highest mountain in the world. Anyway, K-2 formed when two plates moved together and created a mountain.Well see you guys later!
