Some transform boundaries occur beside or within a continent, sliding one large crustal block past another, the San Andreas fault in California is an example of this. If you look at most plates, the different sides of the plates will move differently relative to the surrounding plates. Transform faults or transform boundaries also link different types of plate boundaries. Younger parts of the plate are warmer and higher than older parts. Opposite sides of the fracture zone have different elevations because they formed by seafloor spreading at different times in the past, so they have had different amounts of time to cool and subside after forming at the spreading center. It no longer separates two plater and instead is within a single plate. ![]() A fracture zone is a former transform fault that now has no relative motion across it. Continuing outward from most transform faults is an oceanic fracture zone, which is a step in the elevation of the seafloor. The overall shape of the ridge mimics the edges of Africa and South America and so was largely inherited from the shape of the original rift that split the two continents apart. The zigzag pattern of mid-ocean ridges reflects the alternation of spreading segments with transform faults. These transform faults link the different spreading segments. The offset you see that are oriented east-west are transform faults along which the two diverging plates simply slide past one another. The spreading direction is parallel to the transform faults and perpendicular to the spreading segments. If we use the mid-ocean ridge in the south Atlantic Ocean as an example you’ll see that spreading occurs along north-south oriented ridges but the spreading is perpendicular to the ridges orientation the spreading is in the east-west direction. So what happens is that transform boundaries form to help accommodate some divergent motion. Spreading centers are these straight lines but they are breaking a curved surface. Transform boundary occurs where two plates slide against each other in a shear movement. The zigzag pattern is basically what happens when you try to draw a straight line on a curved surface. Transform faults combine with seafloor spreading to form a zigzag pattern on the seafloor. In the oceans, transform faults are commonly associated with mid-ocean ridges. Transform boundaries exist along oceanic and continental plates. This causes earthquakes.What is a Transform Boundary? At transform boundaries, plates slip past each other horizontally along transform faults. As a result, when the two plates finally succeed in moving with respect to one another, huge amounts of energy are released. Lest you imagine a slippery, sliding motion, take note that the surfaces involved are exposed to huge amounts of stress and strain and are momentarily held in place. Transform boundaries are those that slide alongside one another. Another extreme formation due to the convergent boundary is the Mariana Trench, the deepest region on Earth. They formed when the Indian plate got subducted underneath the Eurasian plate. Convergent boundaries are responsible for producing the deepest and tallest structures on Earth.Īmong those that have formed due to convergent plate boundaries are K2 and Mount Everest, the tallest peaks in the world. Sometimes, the plate boundaries also experience buckling. ![]() At transform boundaries the two tectonic plates grind past each other. That is, the denser plate gets subducted or goes underneath the less dense one. A transform boundary is the zone between two tectonic plates sliding past on another. When they collide, subduction usually takes place. ![]() Convergent boundaries are those that move towards one another.
