 1.There are threetypes of plate boundaries.  The threetypes of plate boundaries are divergent boundaries, convergent boundaries andtransform boundaries.2.In a divergentplate boundary the plates pull away from eachother.  New crust generates as the divergent plateboundaries pull in oposite directions.

3.A spreadingcenter is where the plates move apart. New crust is created where the spreading center is.4.

The Mid-AtlanticRidge is an example of a spreading center.5.There are threetypes of convergent plate boundaries. The three types are Oceanic-Oceanic, Oceanic-Continental andContinental-Continental.6.

In a subductionzone there are two types of crusts involved. The two types of crust are continental and oceanic.7.They Himalayamountains are formed by a Continental-Continental convergent plate boundary.

8.In a transformplate boundary the crust slide horizontally past eachother.  This type of plate boundary creates transformfaults.9.One of the mostfamous transform faults in western North America is the San Andreas fault.10.Along the SanAndreas fault there are two plates that slide past eachother.  These plates are the Pacific Plate and theNorth American Plate.

11. The plates aredivergent plates.  These types of platesare moving in opposite directions.12. The red linerepresents the area that the land was connected before the two plates shifted.13.

In the moviethey show two types of convergences.  Thefirst convergence is Oceanic-Continental and the second convergence wasContinental-Continental.14.

In Idaho minortransform faults are starting to form. These could possibly worsen over time.15. In Asia theyhave a reverse fault.  These plates causea subduction zone and they were reponsible for the tsunami.16.During Pangeatime North America was attached to Africa, Antarctica, South America,Australia, Asia and Europe. These continents were believed to have been apartof one large land mass.

17. Thedistribution of hotspots seem to be at random on the map.  It seems as though they are very sporadic.18.  Sea floor spreading is messured byMillimeters per year.In which ocean doesthe fastest spreading occur?19. Today, thePacific ocean has the fastest sea floor spreading.

20. A hotspotoccurs when hot regions exist below the plates that provide localized sourcesof high heat energy (thermal plumes) to sustain volcanism.  As the result of a hotspot, many islands haveformed. One island that has formed is Hawaii.
