Detailed explanation-1: -When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
Detailed explanation-2: -The third type of plate boundary is the transform fault, where plates slide past one another without the production or destruction of crust. Because rocks are cut and displaced by movement in opposite direction, rocks facing each other on two sides of the fault are typically of different type and age.
Detailed explanation-3: -Transform boundaries are created when tectonic plates slide past each other horizontally along strike-slip faults or transform faults. Strike-slip faults are large cracks or fractures in the Earth’s crust where the transform boundary movement occurs.
Detailed explanation-4: -The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.
Detailed explanation-5: -A transform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it.
