A. Compare the three main types of plate boundaries. How do they work? How are they similar and different? There are three different plate boundaries. There is convergent, divergent, and transform boundaries. They all do different motions. Convergent boundaries are boundaries where the two plates are coming at each other or converging. Divergent boundaries are boundaries where two plates are moving away from each other or diverging. Transform boundaries are boundaries where two plates are shearing past each other or one plate moves to the left and the other moves to the right.

Convergent Boundary
A convergent boundary consists of two tectonic plates or fragments of the lithosphere that come together. If an oceanic plate was involved subduction would occur. Subduction is when two plates converge and one goes under the other. Usually if there are two oceanic plates coming together the older/denser plate would get subducted. If there was a continental plate with an oceanic plate the oceanic plate would subduct, because it is denser, but it is a whole different story if they are both continental plates. Since they are both continental there is no subduction mainly, but there is a collision. They become crumpled and faulted which make the biggest mountain ranges, like the Himalayan Mountain Range.

B. What real world boundary have you chosen? Where is it located (countries involved, general area of the world, etc.)?My team chose the Cascadia Fault. The plates involved are the Juan de Fuca plate and the North American plate. The countries involved are United States and Canada. It is in northern California, Oregon, and Washington. For Canada it is just the southern part of it. It is in the Northern Hemisphere of Earth.

C. Describe in detail how the plates of your real world example are moving. Pay particular attention to details such as crust types of the plates involved, processes that are ongoing, etc.

D. What...
