Final Exam # 1

A convergent boundary is when both plates come together.(1) When this happens that means it will form mountains. A divergent boundary is when both of the plates come apart.(1) When this happens it will form valley's or rifts.(1) But they could also form earthquakes and volcanoes. A transform boundary is when both of the plates slide past each others just barely rubbing up against.(1) Transform boundaries are known as faults, the most famous fault is San Andreas Fault.(1)
All of these boundaries have other features like the mid-oceanic ridges, which are underwater mountains ranges basically. These are caused when the ocean floor starts to spread part.(1) Plate Boundaries are responsable for the floor spreading, earthquakes,volcanoes, subduction zones because when the plates move then that creates a certain type of boundary and which ever type it creates then that feature happens above earth because of all the pressure forcing it upwards.(1)

By know how and where the plates move the most is a big plus. So that will help us in the future. But some my argue that you don't know when they are going to come so it would be real tough to predict when even though you mostly know where.

Shield volcanoes are low velocity eruptions but can go a long distance in traveling. (2) A Stratovolcano is a type of vocano that is shaped kind of like a cinder cone but with ash.Like for example Mt. Fuji in Japan.(2) Cinder cone volcanoes are smaller types of volcanoes that come out of the small vent up at the top.(2) 80% of these volcaones erupt in the ring of fire. This happens because the ring of fire has the most plate tectonic activity around it(2). There is so many volcanoes, ridges.etc, out there that whenever theres any type of activity something will happen. The worst type of volcano to have is a any type of the Ring of Fire because of how active they are out there in the Pacific Ocean.(2)
