![]() San Andreas Fault (Silicon Valley lies dangerously close to the faultline) along the western coast of USA is the best example for a transcurrent edge on continents.In oceans, transform faults are the planes of separation generally perpendicular to the mid-oceanic ridges.In this kind of interaction, two plates slide past against each other, and there is no creation or destruction of landform but only deformation of the existing landform.The subducted material gets heated, up and is thrown out forming volcanic island arc and continental arc systems and a dynamic equilibrium is achieved.Ĭonvergent Boundary Transcurrent Edge or Conservative Edge or Transform Edge.Near the convergent edge a part of the crust is destroyed, hence the name Destructive Edge.When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction.Himalayan Boundary Fault is one such example. The zone of collision may undergo crumpling and folding, and folded mountains may emerge ( orogenic collision).In this kind of interaction, two lithospheric plates collide against each other.Earthquakes (shallow focus) are common along divergent edges.ĭivergent Boundary Convergence forming Convergent Edge or Destructive Edge.Divergent edges are sites of earth crust formation (hence the name constructive edge), and volcanic earth forms are common along such edges.On continents, East African Rift Valley is the most important geomorphological feature formed due to the divergence of African and Somali plates.Here, the basaltic magma erupts and moves apart (seafloor spreading).Mid-Atlantic Ridge) are formed due to this kind of interaction. In this kind of interaction, the plates diverge ( move away from each other).The intensity and frequency of tectonic activity differs for every segment.Divergence forming Divergent Edge or the Constructive Edge 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. It is a transform boundary formed on the west coast of North America in California. ![]() 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. Now, consider the crust on both the sides of the ridge to be divided into bands of horizontal parallel segments.
