Encyclopedia > Transform boundary

In plate tectonics, a transform boundary (also known as transform fault boundary, transform plate boundary, transform plate margin, strike-slip boundary, sliding boundary, transverse boundary, or conservative plate boundary) is said to occur when tectonic plates slide and grind against each other along a transform fault. The relative motion of such plates is horizontal in either sinistral or dextral direction. Many transform boundaries are locked in tension before suddenly releasing, and causing earthquakes. The tectonic plates of the world were mapped in the second half of the 20th century. ... The tectonic plates of the world were mapped in the second half of the 20th century. ... A transform fault is a geological fault that is a special case of strike-slip faulting which terminates abruptly, at both ends, at a major transverse geological feature. ... This article or section is in need of attention from an expert on the subject. ... In astronomy, geography, geometry and related sciences and contexts, a plane is said to be horizontal at a given point if it is locally perpendicular to the gradient of the gravity field, i. ... A sinistral is a horizontal movement of blocks either side of a geological fault. ... A dextral is a horizontal movement of blocks either side of a geological fault. ...


Most transform boundaries are found on the ocean floor, where they often offset active spreading ridges to form a zigzag plate boundary. However, the most famous transform boundaries are found on land. The most well known transform boundary in the world is the San Andreas fault. Scientists predict that in about ten million years, Los Angeles and San Francisco will be side by side.[1] Age of oceanic crust. ... View of the San Andreas Fault on the Carrizo Plain in central California, 35°07N, 119°39W The San Andreas Fault is a geological fault that runs a length of roughly 800 miles (1300 kilometres) through western and southern California in the United States. ...

The fracture zone that forms a transform plate boundary is known as a transform fault.
A strike-slip fault is a simple offset, however, a transform fault is formed between two different plates, each moving away from the spreading center of a divergent plate boundary.
Another example of a transform boundary on land is the Alpine Fault of New Zealand.

Plate boundaries are the home of the majority of the world's active volcanoes with the Pacific Plate's Ring of Fire being most active and famous.
The genesis of divergent boundaries is sometimes thought to be associated with the phenomenon known as hotspots.
Divergent boundaries are typified in oceanic lithosphere by the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and, in continentental lithosphere by rift valleys such as the the famous East-African Rift.
