​​THE TYPES OF PLATE MOVEMENTS = =

=__DIVERGENT BOUNDARIES-__ //This is were two plates move away from each other and magma rises up from the earth.//=

A classic example is the **//__Mid Atlanic Ridge__//**
 * This Ridge takes up the space that is in between the Plate boundaiers.
 * The Ridge connects all the oceans in the world.
 * Volcanoes and underwater mountains form from the seam of the Mid Atlanic Ridge.
 * The Ridge grows 2.5cm per year and 25km in a million years


 * THE GREAT RIFF IN AFRICA**
 * Another example would be the the Great Riff in Africa.
 * The Red Sea is will dump into this new oecan in the next 30 million years.
 * The Great Riff in Africa grows 1 inch per year.
 * People are prodiecting that the Riff will grow up to 186 miles long.
 * The length right now is unknown for now.

=__CONVERGENT BOUNDARIES__- these types of boundiers move towards each other **THE** **HIMALAYAS**=
 * THE GREAT CRACK IN HAWAII**
 * The length is 8 miles long
 * The width is 50ft
 * And with a depth of 66ft
 * When this crack was formed is unknown
 * There has been some evidence that it was formed from a giant lava tube
 * People say that when this crack spilts the piece will fall into the water.
 * Then a mega Tsunami will come out of the water from earthquake that splits the crack.
 * The mountain range is the highest point in the world
 * The Himalayas are also a very young mountain at around 55 million years old
 * They were formed from Indina running into Eurasain.
 * This is how Indina plate is under subdustion which is going under Eurasian's plate
 * Thus in forming the Himalayas
 * This is a continent-continent convergences

=**THE ANDES**=
 * This mountian range was formed from the Nazca Plate and the South American Plate coming together.
 * The Nazca plate is in a subduction zone with the South American Plate.
 * This is coming together as a ocean-ocean convergences and then forming deep trenches like the Mariana Trench in the North Pacific Ocean



=JAPAN=
 * Japan is also formed by ocean to ocean convergences.
 * When this type of collisions happen they become underwater volcanoes.
 * Then they spit out magma and form the Arc Island which are Japan

=__TRANFORM BOUNDARIES-__ When two plates grind past each other=



​​

=San Andreas Fault= = =
 * This fault is in California.
 * It is a great example to show what a Transform Boundary is.
 * The fault is also known as the strike-slip fault
 * When in halting motion it can trigger earthquakes of mass size like the one in 1906

=Jaun de Fuca Plate= ​​ = =
 * This Plate and the North American Plate caused the San Andreas fault
 * Alaska has been having many earthquake from the Juan de Fuca Plate and the North American Plate rubbing together.
