 * There are Three main types of tetonic boundaries. They are The convergent boundarie were plates move into one another, Transform boundary when plates move sideways in relation to each other, and Divergent boundaries when plates move apart from each other.

convergent boundries-** convergent boundary is a boundary between two plates that are moving toward each other or converging. Convergent boundries occur when a plate of ocean dives which is a process callled subduction under a landmass.As the convergent boundries oceanic plate desends it is forced into higher temperature. When the materials reach the subducting plate the melting temperature and patrial melting begins. The buoyant magma is the surrounding mantle which is a magma chamber, if it rises to a surface without any solidfying magma will brake through thats how a volcano will erupt. The cascade mountain Range is were an volcano erupted from the volcanoes above the melting oceanic plate. The mountain ranges are formed as the convergent boundaries overlying plates lift up. Convergent boundaries have two broad classifications for convergent boundaries which are subduction and collision boundries. Subduction boundaries occurs when an oceanic plate plunges beneath another plate. The collison boundrie occurs when two continents collide and are welded into a single, larger continent. Convergent boundaries can be found at the Island of Indonesia, Mariana Islands, Western coast of South america, and the Himalayas. The Himalayas is the worlds tallest mountain that was formed at a collision boundary.This is the Convergent boundarys sub types, plate motion, and some examples of plate mootion how and were it happen.

 * Divergent Boundaries**- Divergent Boundaries are located between two lithospheric plates that are moving apart. Most Divergent boundaries are located along the ocean floor and have rift valleys that are deep valleys located at the center of the mid-ocean ridge. Sea floor spreading is a process were molton rocks force their way upward through cracks, and rifts along the valley. they cool and harden which forms oceanic crust while the old oceanic crust moves away from the mid-ocean ridge. Fracture zone are located perpendicular to the ridge.Earthquakes have been a sourse of movement around the fracture zone. The divergent boundarie has hydrothermal vents that are located on the Mid-Atlantic Ridge. The East Pacific Rise also, have hot springs which rise up from the hydrothermal vents on the ocean floor. The characteristic features of a divergent boundary is the mid-ocean ridges, rift valleys, earthquake activity at fracture zones along the mid-ocean ridges, and volcanic activity. This is divergent boundarys sub types, plate motion, and some examples of the plates motion.

 * Transform Boundarie****s-** Transform boundaries are located between two plates that are sliding past each other. The North American and Pacific Plate are sliding passes each other along the San Andreas Fault in California is one place were an earthquake was caused by a Transform boundary in 1906 because of the two plates passing each other which is known as the strike slip faults. North Anatolian Fault located in Turkey is were another earthquake took place because of the Arabian and African plate are sliding passed each other. There is a modern day indian and Australian plate located near India and Aisa.When a a segment offsets a fracture zone on the mid-ocean ridge it is known as a transform boundarie.. Transform boundaries movement are not uniform. This is how transform boundariess sub types, motion, and some examples of the plates motion and were it took place.
