  __Convergent Boundaries: __ Convergent boundaries occur where a plate of ocean dives, in a process called subduction, under a landmass.

 Here's how convergent boundaries work: As the plate on top lifts up it forms mountain ranges. The "diving plate" or the one being pushed under melts and most of the time is spewed out into volcanic eruptions. An example of this would be the Andes mountains formed in South America. So basically convergent boundaries are just 2 plates colliding as this is going on one gets pushed under. The one pushed under is melted and destroyed. Ocean- Ocean Convergiences:  During ocean to ocean convergiences, one plate usually "dives" beneath the other. This forms deep trenches like the Marina Trench in the North Pacific Ocean... this is the deepest point on Earth. These collisions may also form under water volcanoes,that may eventually build up to islands. A n example of this would be the Hawaiin islands. Where the pacific plate worked itself to eventually build up volcanoes. Which then turned into islands. Ocean-Continental Convergiences:  Long, narrow,curvy trenches that are created by subduction. These trenches can be as large as thousands of kilometers long and 8 to 10 kilometers deep cutting the ocean floor. This is all caused by oceans crashing into continents. An example of this would be: off the coast of South America along the Peru-Chile trench oceanic plate Nazca is pushing and being subducted under the continental part of South America's plate.  Continental-Continental Convergiences:  When two continents meet head on neither of them is subducted. Because,continental rocks are light like colliding icebergs, they resist a downward motion. Instead the crust buckles and is pushed upward or sideways. Basically it forms mountains. I think the best example of this would be the Himalayan mountains. About 55 million years ago the Indian and Asian plates collided. Slowly giving rise to the Himalayan mountains, the highest mountain system on Earth. As the continents mash-up the mountains get higher. Mount Everst is the highest point on Earth. Because of these convergiences we can witness something truly amazing. (see picture above)

 Divergent Boundaries: At divergent boundaries in oceans, magma from deep in the Earth's mantle rises toward the surface and pushes apart two or more plates. Here's how divergent boundaries work: Mountains and volcanoes rise along the seam. This process renews the ocean floor and widens the giant basins already there. The single mid-ocean ridge system connects the world's oceans making the ridge the longest mountain range in the world. Divergent boundaries work a tad different on land however. On land giant troughs are formed. Such as the Great Rift Valley in Africa. (see picture above) This happens where plates are tugged apart. If these plates in Africa continue to diverge in millions of years from now Eastern Africa will split from the continent to form a new landmass. WOW!!! That's pretty amazing! A mid-ocean ridge would then mark the boundary between the plates. Another example from divergent boundaries would be... As for any place where divergent boundaries occur new crust is formed as<span style="font-family: "Comic Sans MS",cursive; font-size: 120%;"> the plates are pushed away <span style="font-family: "Comic Sans MS",cursive; font-size: 149%;"><span style="font-family: "Comic Sans MS",cursive; font-size: 120%;"> from each other. <span style="font-family: "Comic Sans MS",cursive; font-size: 149%;"> Divergent Plate Boundary Oceanic: When the divergent boundary occurs beneath the oceanic lithosphere, a rising convection current below lifts the lithosphere. This produces a mid-ocean ridge. An example of this type of divergent boundary would be the Mid-Atlantic Ridge. This is a specific high area compared to the sea floor surrounding it. Because of the lift from the convection current flow. Obviously the plate used here would be the atlantic plate. <span style="font-family: "Comic Sans MS",cursive; font-size: 149%;"> Divergent Plate Boundary Continental: When the divergent boundary occurs beneath a thick continental plate, the pull-apart s not vigorous enough to create a clean, single break through such a thick plate material. Instead it usually gets fractured into a rift-shaped structure. The consequence of this is usually earthquakes. An example of this would be the Red Sea. The Red Sea is a completely developed rift.

<span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">__​Transform Boundaries:__ A transform boundary is where 2 plates grind past each other along what are called "strike-slip faults". <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;"> An example of the effects of these boundaries would be the San Andreas Fault in California. As we know California experiences many earthquakes. That's because of the giant tectonic plate it is laying on. The San Andreas Fault was caused by two plates grinding past each other. This triggerd an earthquake causing a giant crack to form right in our sight. The plate involved in this was: the Juan De Fuca Plate. Located right along California. (fault pictured at very bottom) <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;"> Another example of this would be: in the Phillipines. For the last 35 years the Phillipines have been affected by 10 earthquakes all with magnitudes greater than 7.0. Of course this was all thanks to the Phillipines plate. <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;"> My final example will deal with once again the Phillipine plate as well as the Pacific plate. The Pacific plate is constantly moving northwest. This causes it to subduct itself under the eastern ridge of the Phillipine plate. This causes major earthquake activity.(pacific plate pictured above) <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">
 * R**<span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">These boundaries don't produce amazing features like mountains or oceans. However, the haulting motion of the plates often triggers earthquakes. Transform boundaries are also known as the conservative plate boundary. Unlike other movements of our tectonic plates transform boundaries neither destroy or create new crust while they are sliding past each other.
