1.There are three
types of plate boundaries. The three
types of plate boundaries are divergent boundaries, convergent boundaries and
2.In a divergent
plate boundary the plates pull away from eachother. New crust generates as the divergent plate
boundaries pull in oposite directions.
center is where the plates move apart.
New crust is created where the spreading center is.
Ridge is an example of a spreading center.
5.There are three
types of convergent plate boundaries.
The three types are Oceanic-Oceanic, Oceanic-Continental and
6.In a subduction
zone there are two types of crusts involved.
The two types of crust are continental and oceanic.
mountains are formed by a Continental-Continental convergent plate boundary.
8.In a transform
plate boundary the crust slide horizontally past eachother. This type of plate boundary creates transform
9.One of the most
famous transform faults in western North America is the San Andreas fault.
10.Along the San
Andreas fault there are two plates that slide past eachother. These plates are the Pacific Plate and the
North American Plate.
11. The plates are
divergent plates. These types of plates
are moving in opposite directions.
12. The red line
represents the area that the land was connected before the two plates shifted.
13.In the movie
they show two types of convergences. The
first convergence is Oceanic-Continental and the second convergence was
14. In Idaho minor
transform faults are starting to form.
These could possibly worsen over time.
15. In Asia they
have a reverse fault. These plates cause
a subduction zone and they were reponsible for the tsunami.
time North America was attached to Africa, Antarctica, South America,
Australia, Asia and Europe. These continents were believed to have been apart
of one large land mass.
distribution of hotspots seem to be at random on the map. It seems as though they are very sporadic.
18. Sea floor spreading is messured by
Millimeters per year.
In which ocean does
the fastest spreading occur?
19. Today, the
Pacific ocean has the fastest sea floor spreading.
20. A hotspot
occurs when hot regions exist below the plates that provide localized sources
of high heat energy (thermal plumes) to sustain volcanism. As the result of a hotspot, many islands have
formed. One island that has formed is Hawaii.
