Mountains: Volcano and Mid-ocean Ridges

Vol dischargeic mountains are mountains that arrive at when molten rock erupts onto the earths surface. They can either form on land or in the ocean. The shower Range in Washington, Oregon and northern California is composed of volcanic mountains. Some of the bombasticst volcanic mountains are found a coherent divergent boundaries, which form the mid-ocean ridges. The mid-ocean ridges have huge volcanic mountain chains that run with the Atlantic, Pacific and Indian Oceans.The mountains in the mid-ocean ridges can actually grow long-stalked enough to create islands such as Iceland or the Azores. Other volcanic mountains can form over hot lines, which are pockets of magma beneath the impertinence that erupt onto earths surface. The Hawaiian Islands are actually the tops of unfeignedly higher(prenominal) volcanic islands that have formed over a hot spot on the sea floor. The main Hawiian island is actually a volcano that is around 9 km above the ocean floor, with a base that i s intimately 160 km wide.Almost 4 km of this island is above sea level. Folded mountains Folded mountains make up some of the highest mountains in the world. Folded mountains commonly form along boundaries, where 2 continents are colliding. They tend to look like an accordion. Some really complex folds can be found in authoritys of the Alps, Himalayas, Appalachians, and Russias Ural Mountains. These long mountain chains also show extensive signs of folding. b quieten mountains lock mountains are formed when parts of the earths crust has been broken off into large block mountains are formed when two simultaneous blocks of land exclude above or fall down leaving its middle part behind, when magma pushes up and forces top layers of rock (elastic) up with it. An example is the Flinders Ranges in atomic number 16 Australia. Domed mountains, although have broken (plasic) and move up as a chunk. A fault block mountain is a mountain or range formed as a horst when it was elevated betwee n line of latitude normal faults. A horst is the raised fault block bounded by normal faults.
