Is the San Andreas Fault convergent or transform?
transform
Tectonic Plate Boundaries The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.
Is the San Andreas Fault an oceanic transform fault?
The San Andreas Fault is part of a transform plate boundary that disrupts the topography of an ancient subduction zone.
What type of transform boundary is the San Andreas Fault?
continental transform fault
The San Andreas Fault is a continental transform fault that extends roughly 1,200 kilometers (750 mi) through California. It forms the tectonic boundary between the Pacific Plate and the North American Plate, and its motion is right-lateral strike-slip (horizontal).
Was the San Andreas earthquake a transform boundary?
The San Andreas Fault that runs through much of California is an enormous transform plate boundary. It is the plate boundary between Pacific and North American plates. The largest earthquake in recorded history on the San Andreas Fault occurred in 1906.
Is San Andreas Fault a divergent boundary?
The San Andreas Fault marks the junction between the North American and Pacific Plates. The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. …
How did the San Andreas Fault form?
Starting at 30 million years ago, the westward-moving North American Plate began to override the spreading ridge between the Farallon Plate and the Pacific Plate. The change in plate configuration as North American Plate began to encounter the Pacific Plate resulted in the formation of the San Andreas Fault.
Which type of fault best describes the San Andreas Fault Why?
The San Andreas Fault—made infamous by the 1906 San Francisco earthquake—is a strike-slip fault. This means two fault blocks are moving past each other horizontally. Strike-slip faults tend to occur along the boundaries of plates that are sliding past each other.
What caused the San Andreas Fault to form?
Is the San Andreas Fault a divergent boundary?
How is the San Andreas Fault formed?
The San Andreas Fault System grew as a remnant of a oceanic crustal plate and a spreading ridge (like the Juan de Fuca Ridge) were subducted beneath the North American Plate as it moved west relative to the Pacific Plate.
How has the San Andreas Fault changed over time?
Scientists have learned that the Earth’s crust is fractured into a series of “plates” that have been moving very slowly over the Earth’s surface for millions of years. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east), causing earthquakes along the fault.
