FC: San Andreas Fault
2: Boundary Type | The San Andreas Fault is a Transform Boundary type. The two plates grind against each other, which create earthquakes all along the fault.
3: What is a Fault? | A fault is a planar crack in a rock along which slippage has taken place. Most faults are small even microscopic and not are not important. Some faults are many miles long, and cause catastrophic damages. | Turkey's North Anatolian Fault
4: Thedfdsffdshfjs3 kl | If the motion is mostly horizontal and parallel to the fault plane, the fault is called a strike slip (or transform) fault. The SAF is a right lateral transform fault. This means that if two people face each other across the fault and it moves, each person will see the other person move to the right. | Here the small Juan de Fuca plate is sub ducting under the North American Plate.
5: Similar Faults | The North Anatolian Fault is a major active right lateral-moving strike-slip fault in northern Anatolia which runs along the transform boundary between the Eurasian Plate and the Anatolian Plate.
6: Contrast (Convergent Boundary) | The Convergent boundary created a trench where the two plates collide. This trench is very different than the fault. The trench is created by two plates colliding while the San Andreas Fault is created by the two plates grinding against each other.
7: Driving Forces | Large Convection currents cause the plates to be pulled and pushed along the fault line. As the magma reaches the top of the plate it moves the plate along with it.
8: Isostasy | Isostasy is a term used in geology to refer to the state of gravitational equilibrium between the earth's lithosphere and asthenosphere such that the tectonic plates "float" at an elevation which depends on their thickness and density. | The North American is sitting on asthenosphere that is denser than the asthenosphere that the Jaun de Fuca Plate does. The North American Plate sits slightly more elevated than the Juan de Fuca plate.
9: Earthquakes | Earthquake stress is built up in rocks when two plates that are trying to move push against one another. Because of friction between the plates at the fault, they cannot slide freely. Instead, they strain and build up energy, like compressing a spring.

11: Interesting Facts | The San Andreas Fault is the most famous fault in the world. Its notoriety comes partly from the disastrous 1906 San Francisco earthquake. The grinding plates and earthquakes are gradually warping and reshaping Califonia. In a few million years, California will look very different than it does today. Consider this: California is about 1000 miles long. That's 1000 miles x 5280 ft/mile x 12 inches/ft = 63,360,000 inches At the measured slip rate of about 2.5 inches per year, it will take 63,360,000 inches/ 2.5 inches/year = 25.3 million years for the state to be sheared and twisted beyond all recognition.
