How are mountain ridges made?

Answer 1

I'm guessing all you want to know is how are mountains made. if you are, here is the answer.

as you may know, the continents and oceans are sitting on top of tectonic plates. there are two types of plates that i know of, oceanic, which is very dense, and continental, which is less dense than oceanic. when these plates shift, they cause an earthquake. sometimes, the plates collide. ---><--- like these arrows show. when this happens, the denser plate subducts (goes under) the less dense plate. so whenever plates collide, the oceanic plate will go under the continental plate. when the plate subducts, it melts, and somewhere else new plates are being formed. the plate subducting causes the continental plate to rise up, creating mountains. this is a very slow process, though. mountains grow about 2.5 centimeters per year. that's as fast as your fingernails grow. so, it takes thousands of years to form mountains. like the Himalaya's, where mt. Everest is located.
