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. Now, consider the crust on both the sides of the ridge to be divided into bands of horizontal parallel segments. The divergent boundary is not a straight line however, it is zigzag and crooked. (This occurs most commonly at a mid-oceanic ridge like the Mid-Atlantic Ridge in the Atlantic Ocean). Let us imagine that there are two divergent tectonic plates such that one plate is moving away from the other. It is a tectonic plate boundary, where two plates slide past each other horizontally, without forming or destroying the tectonic crust. spreading centers), or occasionally, convergent plate boundaries (e.g. He proposed that such large faults connect two divergent plate boundaries (e.g. The Canadian geophysicist John Tuzo Wilson is the father of the concept of transform boundaries. However, some regions like the transform boundaries, which although tectonically active, are the silent revolutionaries, as they do not alter the shape of the Earth phenomenally. Some such activities are responsible for the formation or destruction of geological features on land. The interaction between landmasses and water bodies is guided by the activities in the Earth’s interior. Plate tectonics have given the Earth’s surface its present shape. The Indo-Australian, Pacific, and Antarctic plates meet at the Macquarie Triple Junction south of New Zealand. ![]() It is the region where three tectonic plates collide with each other. This ScienceStruck article provides information regarding this boundary is, along with its examples. *”Physical Geology” by Steven Earle used under a CC-BY 4.0 international license.A type of plate tectonic boundary, other than the convergent and divergent boundaries is the transform boundary. west coast (Steven Earle, “Physical Geology”).Īs we will see in the next section, earthquakes are common along transform faults, as the two plates slide past each other. For example, the Queen Charlotte Fault connects the north end of the Juan de Fuca Ridge, starting at the north end of Vancouver Island, to the Aleutian subduction zone.įigure 4.7.1 Transform faults along the U.S. Transform faults do not just connect divergent boundaries. ![]() The part of California west of the San Andreas Fault and all of Baja California are on the Pacific Plate. An example is the San Andreas Fault, which connects the southern end of the Juan de Fuca Ridge with the northern end of the East Pacific Rise (ridge) in the Gulf of California (Figure 4.7.1). Some transform faults connect continental parts of plates. As explained in section 4.5, most transform faults connect segments of mid-ocean ridges and are thus ocean-ocean plate boundaries. Transform boundaries exist where one plate slides past another without production or destruction of crustal material. Modified from "Physical Geology" by Steven Earle*
