Their are 3 types of plate motions.

__**Convergent Boundaries-**__ Is when a plate collides or dives under another. Ex:When the plates go under another the Himalaya Mountains grow every year. Another example of subduction is the Andes. Last is Mount Everest which gets taller every day.

Is when magma rises and pushes the plates apart. Ex:On land, giant troughs such as the Great Rift Valley in Africa. Alantic Mid-ocean ridge is also and example. Last Iceland is an example of divergent Boundaries.
 * __Divergent Boundaries__**-

Is when two plates grind past each other along what are called strike-slip faults. Ex:The San Andreas Fault in California is an Example of transform boundaries. Next the gulf of california is an example. Last African and Eurasian plates slide past each other and is creating a fualt in the Alantic Ocean.
 * __Transform Boundaries__**-

Earthquakes occur when plates collide or slide. Most of all the planet's earthquakes occur by the pacific ocean, called the Ring of Fire.
 * __Earthquakes__ -

**__Volcanoes__ - Thick magma and large amounts of gas build up under the surface and it erupts. Lava flowing from volcanoes can reach 2,000 degrees fahrenheit of more.
