![]() ![]() The intensity and frequency of tectonic activity differs for every segment. ![]() It has been divided into three segments of northern, central, and southern. The fault zone is around 1,300 km long and runs through the state of California. The fault joins the East Pacific Rise and the South Gorda – Juan de Fuca plate. The Pacific plate is moving alongside the North American plate for millions of years. Parts of these plates get stuck at the places where they touch. A transform fault or transform boundary, also known as conservative plate boundary since these faults neither create nor. They are connected on both ends to other faults. No lithosphere is destroyed or created, and mountain chains are not built at transform boundaries. Shear stress operates at transform boundaries, which involves sliding motion. ![]() It is a transform boundary formed on the west coast of North America in California. A transform boundary is formed as tectonic plates slide horizontally past each other. A transform fault is a type of strike-slip fault wherein the relative horizontal slip is accommodating the movement between two ocean ridges or other tectonic boundaries. Transform fault (the red lines) A transform boundary occurs when two tectonic plates move past one another. They are also known as conservative boundaries, as no new crust (lithosphere) is created or destroyed. There are, however, a few transform boundaries that occur on continents. They generally offset the spreading ridges on the ocean floor by zigzag plate margins. They also connect two trenches at subduction zones (where one tectonic plate is going underneath another), or a ridge with a trench. They generally connect the segments of the diverging mid-oceanic ridges. Transform faults end at the junction of another plate boundary or another fault. One segment of the east moving part of the ridge slides alongside another segment of the westward moving part of the ridge. Transform faults occur on the sides of these segments, which during divergence, move past each other. The continental plate is pushed upward creating mountains like the Andes.Now, consider the crust on both the sides of the ridge to be divided into bands of horizontal parallel segments. As the Ocean plate is pushed under the continental plate the sedimentary layers are melted creating volcanos. ![]() The resulting subduction zone creates a deep ocean trench and mountains. An example is the Pacific Coast of South America. The most common convergent boundary is where an ocean plate is being pushed under a continental plate. An example is the rift valley of East Africa.Ĭonvergent boundaries occur where two plates are being pushed together. Examples are the mid ocean ridges and Icelandic volcanoes.Īlso because the plates are moving in opposite directions new crust is formed between the two plates. These boundaries produce shield type volcanos that spew out ballistic lava. A transform boundary is formed as tectonic plates slide horizontally past each other. Jason Morgan, one of the several outstanding pioneers in plate tectonics, recognized that transform faults are zones where opposing lithospheric plates slip past one another. This pushing creates frequent and severe earthquakes, like the famous San Francisco earthquake.ĭivergent boundaries occur where two plates are being pushed apart as new crust and magma comes to the surface. Transform faults are the only segments of fracture zones that are seismically active. Transform faults occur where two plates are pushing against each other at a close to a 180 degree angle. ![]()
