= = = = =Transform Fault Boundary: (great! 8 points)=

=
A transform fault runs along the boundary of a tectonic plate. Most of the transform faults cut the ocean floor. A transform fault occurs when tectonic plates slide and grind against each other. The plates slide in a horizontal motion.======

=Locations: (good list of locations-image links are broken? 5= =points)=

=
The most known fault line is the San Andreas Fault. This fault runs a length of roughly 810 miles through California in the United States, and through Baja California in Mexico. It forms the tectonic boundary between the Pacific Plate and the North American Plate. Another place is the Dead Sea transform. It runs along the boundary of two tectonic plates, the African plate on the west and the Arabian plate on the east.======

=Associated Geologic Features: (okay, a little lacking-6= =points)=

=Associated Geologic Events (good---but pictures, etc? 6 points)=

=
Earthquakes often occur along transform faults. This occurs when two plates on each side of the fault line start to grind sideways in different directions. As the plates grind against each other they get "stuck", eventually as they continue to push together they create stress and a sudden jolt of movement occurs causing an earthquake.======

=Famous Earthquakes (good! 8 points)=

=
In 1857, 1906 and 1989, major earthquakes happened along the San Andreas Fault. The most significant earthquake though, was the earthquake of 1906. It ruptured a total of 296 miles. The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada.======
