![]() What type of crust is involved in transform boundaries?Ī transform fault is a special case of a strike-slip fault that also forms a plate boundary. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. Natural or human-made structures that cross a transform boundary are offset-split into pieces and carried in opposite directions. Two plates sliding past each other forms a transform plate boundary. What will be formed in each type of transform plate boundary? The build-up of pressure between the two plates along a transform fault produces earthquakes. Transform faults are called conservative boundaries because no crust is created or destroyed the plates just move past each other. Transform faults occur at plate boundaries. Landforms created by divergent plates include the Mid Atlantic Ridge and the Great African Rift Valley. What landforms do divergent boundaries form?Īt DIVERGENT boundaries the plates move apart allowing molten magma to rise and form new crust in the form of ridges, valleys and volcanoes. California’s San Andreas fault is a transform boundary. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. At transform boundaries lithosphere is neither created nor destroyed. ![]() Transform boundaries are places where plates slide sideways past each other. A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. ![]() What causes transform boundary to form?Ī transform plate boundary occurs when two plates slide past each other, horizontally. A well-known example of a transform plate boundary is the San Andreas Fault in California. Places where these breaks occur are called faults. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. This is known as a transform plate boundary. 6 What are facts about a transform boundary?.5 What are the real life examples of transform boundary?.4 What will be formed in each type of transform plate boundary?.2 What causes transform boundary to form?.Numerous earthquakes occur along the San Andreas Fault, which passes through highly populated areas of California. The San Andreas Fault, an example of a transform fault, where two plates slide past each other. Here the Pacific Plate is sliding past the North American Plate. This satellite photograph shows Point Reyes, California, and the San Andreas Fault. These boundaries are characterized by shallow earthquakes. Transform boundaries form where two plates slide past each other. Earthquakes can occur in the trench (where they can cause tsunamis) and all along the subduction zone. The deep ocean trench marks the plate boundary and is where the subduction of the ocean lithosphere begins. This results in the destruction of the ocean lithosphere and the formation of magmas (with island arc volcanoes above). In the diagram above, the ocean lithosphere subducts underneath the continental lithosphere. ![]() Note the formation of a trench at the plate boundary and a line of volcanoes called an "island arc". The collision of the plates causes subduction and destruction of the ocean plate. These boundaries are identified by their high mountains, volcanic island arc chains, and deep earthquakes.Īn ocean plate converges with a continental plate. These boundaries often form major mountain chains. (Diagram by Phyllis Newbill)Ĭonvergent boundaries form where two plates collide. In oceanic rifts, there is a midocean ridge with a central rift valley, volcanoes, and the formation of new ocean crust. Note the central rift valley that includes volcanoes. The diagram shows a typical continental rift. Continental rift valleys are characterized by normal faulting and basalt-rich volcanoes. At these boundaries, two neighboring plates move away from each other. Divergent Plate Boundariesĭivergent boundaries can be mid-ocean ridges or continental rift valleys. Where they slide past each other, the boundary is a transform boundary. Where they move toward each other, the boundary is convergent. Where plates move away from each other, the boundary is divergent. Three types of plate boundaries exist.Principles of Plate Tectonics (Part 2) Plate Boundaries
