 * Dynamic Earth**

The Earth is covered in plates that make up its lithosphere. There are major and minor plates but neither are more important than the other. There are three types of boundaries and they are convergent, divergent, and transform boundaries.

An example of a convergent boundary is the Caribbean Volcanic Arc. They're islands of the eastern side of the Caribbean plate and they're in contact with the South American plate. The plates that collided to make these islands were probably the Caribbean plate and North American plate. Another example of a convergent boundary is the Cascades Volcanoes. The volcanoes are a north-south trending line of volcanoes. They lie on the North American Plate. Their location is slightly inland from the boundary with the Juan de Fuca plate. The plates that probably collided to make these volcanoes were the Juan de Fuca plate and the North American plate. The last example is the Andes Mountain Range. They have volcanic activity on the South American plate. They're a few hundred miles east of its collision with the Nazca plate. The plates that made this mountain range were the Nazca plate and the South American plate.
 * __Convergent Boundaries__** are plates that move into one another. During the process, a plate collides with or dives under another.

The Red Sea is an example of a divergent boundary. It was formed from the African and Arabian plates diverging. The shore lines have a jigsaw puzzle fit meaning they were together at one point and seperated to form the sea. Another example is the Mid-Atlantic Ridge. The fissure marks the position of it. Fissure is a narrow opening produced by cleavage or seperation of parts. The Mid-Atlantic Ridge has lateral offsets that made transform faults. The plates that made this were the African and the North American plates. Finally, the Mid-Atlantic Ridge above Sea Level at Iceland is a divergent boundary. It has volcanic activity. There is linear fracturing within the rift valley of it. The North American and Eurasian were the plates that most likely made the Ridge.
 * __Divergent Boudaries__** are when plates move apart. During this process, magma rises and pushes plates apart.

They dont create volcanoes or mountains but they can create serious earthquakes. The Alpine Fault, South Island, New Zealand is one example. It has a strike slip fault and it's between the Austrailian and Pacific plates. The plates that caused this were the Austrailian and the Phillipine plates. Also, the San Andreas Fault Zone are Transform boundaries. They have linear fractures. The faults are formed in the fracture zone between the Pacific and North American plates. There was an earthquake in 1906 in California that was very severe and very tragic. This earthquake was most likely caused by the Juan de Fuca and North American plates grinding against eachother. Also, faults are formed in the fracture zone between the Pacific and North American plates.
 * __Transform Boundaries__** are where plates move sideways in relation to eachother. This means that two plates a grinding againts eachother.
