How does mountains formed ?
You mean "How are mountains formed?"Well there are several ways and it is much too lengthy to be able to answer here. Here is a link that explains it~http://www.universetoday.com/29833/how-mountains-are-formed/
Two tectonic plates that are underground end up colliding together and one goes on top of each other and the ground moves upward and thus: Mountain!:)
2 tectonic plates collide and they both, because of all the pressure, get forced upward forming a mountain. Think of it like this: if your 2 hands, flat, were tectonic plates and they collided, wouldn't they go up? Where else would they go?
try googling it.. i did once and i think it said, when plates go over each other, and the land there is elevated.. something like that.
mountains can be formed from molten magma or can be formed from sediments of rock by winds, erosion, e.t.c
two rocks pile up for every grammatical error
