The land mountains were formed due to collision of the tectonic plates (earth's solid foundations). Collision of the tectonic plates was induced when the earth started to spin. The marine mountains (under water oceanic ridges) were formed (and still forming) from the lava flowing from cracks in the oceans' floors.
Formation of the mountains The earth started its motions after the creation of the heavens and the earth was completed. As a result of the spinning motion of the earth, parts of the earth's crust were compressed and pushed upward thus forming the land mountains.
