Transcript of mountain type

Types Of Mountains by Kelsey and Nicole and vincci Dome Mountains The Dome Mountains were formed by Magama pushing its way up under the earths crust without actually erupting onto the surface. The magma pushes up overlayed rock layers at some point the magma cools and forms hardened rock, which are layers. The uplifted area created by the magma is called a Dome because of looking like the top half of a sphere. The rock layers of the hardened magma are warped upward to form the dome but the rock layers of the surrounding areas remain flat. Fold Mountains It's the most common mountain and the worlds largest mountain ranges. The ranges were formed over million over years. They're formed when two plates collide head-on and they're edges crumble like how a piece of paper folds when pushed together. Anticline (A submerged border of a continent that slopes gradually and extends to a point of steeper descent to the ocean bottom.) Sincline (syncline is a downward curving fold in a rock formation, where the strata dip toward the center of the structure.)

Examples of Fold Mountains:
-Himalayan Mountains in Asia --> formed when India crashed into Asia and pushed up the tallest mountain range on the continent
-The Alps in Europe
-The Andes in Sount America --> formed by the collision of the Sounth America continental plate and the oceanic Pacific Plate.
-The Rockies in North America
-The Urals in Russia Fault- Block Mountains Formed when large areas of bedrock (the solid rock beneath a layer of soil, or gravel) are widely broken up by faults creating large vertical displacement (In tectonics, vertical displacement is a shifting of land in vertical direction, resulting in a permanent changes elevation) of continenetal crust (the basement complex of rock, that is, metaphorsed (to metamorphosis or metamorphism.) sedimentary and volcanic rock with assoiciated igneous rocks mainly granitic, that underlies the continents and the continental shelves(A submerged border of a continent that slopes gradually and extends to a point of steeper descent to the ocean bottom.) two types of block tilted and lifted.
Examples: seirra nevada mountains in north america and the aarz mountains in germany.
Plateau Mountains Formed by erosion or layers of lava, rivers and streams erode away at valleys everntually leaving mountains on each side of the valley. Volcanic Mountains Is an opening or rupture (The process or instance of breaking open or bursting. The state of being broken open) in a planet surface or crust which allows hot magma or ash and gases to escape below the surface. Formed do to volcanic eruptions and when magma erupts and piles on the surface.

Example:
- Mount St.Helens in North America
- Mount Pinatubo in the Philippines
-Mount Kea and Mount Loa in Hawaii VOLCANIC MOUNTAINS Strata (Composite) Volcanic Mountain: Shield Volcanic Mountain: Cinder (Ash) Volcanic Mountain: Seamounts Volcanic Mountain: Calderas Volcanic Mountain: Throws out - besides lava - much ash into the air. Through this the volcanic cone is built up from alternate layers of ash and cinder. An older volcano with a large crater which can be 62 miles (100 km) wide. In this crater many little new caters are formed. An underwater mountain rising from the ocean floor and having a peaked or flat-topped summit below the surface of the sea.
This is a borad, shallow volcanic cone, which arises because the running lava, which is fluid and hot, cools slowly. A tall, cone-shaped mountain in which layers of lava alternate with layers of ash and other volcanic materials, also know as a stratavolcano Mount St. Helens Mount Punatuba Mount (Mauna) Loa Mount (Mauna) Kea Sierra Nevada Mountains Himalayan Mountains The Alps Mountains The Andes Mountains The Rockies (Not sure if it's right...) The Urals Mountains The END. :) keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing. keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.keepgoing.
