![]() Detailed studies of piercing points show the San Andreas Fault has experienced over 225 km of movement in the last 20 million years, and this movement occurred at three different fault traces. The best type of piercing point includes unique patterns that are used to match the parts of a geological feature separated by fault movement. Other types of faults-normal and reverse -tend to be more destructive, obscuring or destroying these features. Transform faults are unique because their horizontal motion keeps a geological feature relatively intact, preserving the record of what happened. At these boundaries new crust is created as magma. Most transform faults are found in the ocean where they offset. Piercing points are very useful for recreating past fault movement, especially along transform boundaries. A Consecutive plate boundary,also known as a divergent boundary,when two plates move away from each other. Transform plate boundaries are where two tectonic plates meet and slide past each other in different directions. A transform boundary is a fault zone where two plates slide past each other horizontally. When a geological feature is cut by a fault, it is called a piercing point. Tectonic plates are large sections of lithosphere, or the Earths crust. The majority of transform faults link the offset segments of oceanic ridges. What is a convergent boundary Boundaries are the types of connections between tectonic plates. Transform faults are so named because they are linked to other types of plate boundaries. Transform the boundaries of the plateImage credit: MBGA transform the plate limit can be done by cutting. ![]() The fault can be seen about halfway down, trending left to right, as a change in the topography. Along the third type of plate boundary, two plates move laterally and pass each other along giant fractures in Earth’s crust. Transform plate boundary definition earth science. This is caused by the San Andreas Fault cutting roughly perpendicular to the creek, and shifting the location of the creek over time. Note as the creek flows from the northern mountainous part of the image, it takes a sharp right (as viewed from the flow of water), then a sharp left. \): Wallace (dry) Creek on the Carrizo Plain, California. The Earths surface or lithosphere comprises tectonic plates which average approximately 50 miles in thickness, and are continuously moving very slowly upon a.
