Convergent boundary- A plate collides into another or dives under another plate. This plate is the main cause for steam pits and under water volcanos of spewing hot lava. This plate is the same plate that is under North America. This boundary has form the deepest part in our earth a.k.a. the Marina Trench. As this plate shifts and moves it forms volcanos begin and spew lava and form to new land as well as cause great destruction. The plate also collides and causes earthquakes.

Divergant boundary- When hot magma forces the plates to separate apart. This boundary makes new volcanos and new moutains to form. A popular example of this boundary is the Great Rift Valley in Africa. Scientist predict in millions of years Africa will split into 2, forming new another ocean. These plates only move 2-10 cm a year, about the size of your finger nail. When new volcanos form in this ocean because of this plate it causes the volcanos to form new land and island in the ocean. = =

Transform boundary- Two plates grinding against each other. Because of this boundary we had the biggest earthquake in California history in 1906. This boundary is the main cause for earthquakes, sunamis and mud slides. The place that is most affected by this plate is China every 50-70 years it has a major earthquake. Scientist predict that in the next 100,000+ years California will break from the U.S. due to the earthquake activity. California has almost 5-15 earthquakes a day!
