The average slip rates in the fault's central region are abo… STUDENT ACTIVITY: New Zealand plate boundary models Activity idea In this activity, students make and/or observe two 3D moving models of the different tectonic plate boundaries under the North and South Islands representing the North Island subduction zone and the South Island Alpine Fault. In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed. Sometimes, a single oblique-slip fault will carry most of the deformation; an example of this is the Alpine Fault in New Zealand. At a transform boundary, two tectonic plates slide past each other. What Happens When Rain Falls On Desert Soils? Image courtesy of the U.S. Geological Survey. Types of Plate Boundaries Camryn Tomlinson. Questions? By the end of this activity, students should be able to: St. Andreas Transform Fault Alpine Fault New Zealand The types of transform fault that are always the longest Oceanic Transform Fault Continental Transform Fault. When two plates come together, it is known as a convergent boundary. Download image (jpg, 76 KB). It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault is a geological fault, specifically a right-lateral strike-slip fault, that runs almost the entire length of New Zealand’s South Island. Transform plate boundaries occur where two lithospheric plate slide past each other horizontally along a single or a group of deep nearly vertical steep fault planes. Rocks that line the boundary are pulverized as the plates grind … Website Satisfaction Survey
In between, through most of the South Island, the two plates grind past each other along the Alpine Fault. On the strike-slip section of the plate boundary through New Zealand (the Alpine fault; Fig. Marine Pollution: How Do Plastic Additives Dilute in Water and How Risky Are They? The mountains are rising at 7 millimetres a year, but erosion wears them down at a similar rate. Convergent Plate Boundary (Ocean-to-Continent). At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Site of the Next Major Earthquake on the San Andreas Fault? This lateral motion of one plate against another can show faults in the surface crust (As the Alpine Fault shows through the Southern Alps) The sliding motion also causes lots of earthquakes along the fault … 202 - Tectonic Plates • pg. Seismic Activity of New Zealand's Alpine Fault More Complex Than Suspected, Southern California Earthquakes Increased Stress on Major Fault Line, 'Inchworm' Pattern of Indonesian Earthquake Rupture Powered Seismic 'Boom'. The fracture zone that forms a transform plate boundary is known as a transform fault. The mountain belts listed above in bold face are at ocean-continents Convergent Plate Boundaries (North American Cordillera, Andes) or continent-continent Convergent Plate Boundary (the Himalayas are the best example of this type of plate boundary). The Alpine Fault is a geological fault, known as a right-lateral strike-slip fault, that runs almost the entire length of New Zealand's South Island. The type of plate boundary at the Alpine Fault is a transform boundary. Each type is the outcome of different forces pushing or pulling on the crust, causing rocks to slide up, down or past each other. The Alpine Fault, marked here by the yellow line, stretches nearly the entire length of Te Waipounamu, the South Island of Aotearoa New Zealand. The formation of Southern Alps is attributed to the tectonic activity, including earthquakes along this transform boundary. For more information, see the following related content on ScienceDaily: Content on this website is for information only. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. The transform fault is simply a strike-slip fault as the plates move, the crust is fractured and broken. 1A) there are opportunities to derive long earthquake records from sediments that, although not offset by fault rupture, are uniquely tied to Alpine fault earthquakes. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. The last such earthquake took place in … The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. 6. The San Andreas fault of California is a prime example of a continental transform boundary; others are the North Anatolian fault of northern Turkey, the Alpine fault crossing New Zealand, the Dead Sea rift in the Middle East, the Queen Charlotte Islands fault off western Canada, and the Magellanes-Fagnano fault system of South America. It forms the sharp line separating the snow-covered Southern Alps in the east from the low coastal plain bordering the Tasman Sea in the west. What are the different types of plate tectonic boundaries. It is not intended to provide medical or other professional advice. Transform Plate Boundaries are locations where two plates slide past one another. The Alpine Fault is a geological fault that runs almost the entire length of New Zealand's South Island (c. 480 km) and forms the boundary between the Pacific Plate and the Indo-Australian Plate. The Alpine Fault cuts through New Zealand. Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. The Alpine Fault, which runs for about 600km up the spine of the South Island, is one of the world’s major geological features. Movement along this fault has uplifted the Southern Alps and helped shape the South Island landscape we know today. However, most of the motion on the fault is strike-slip (side to side), with the Tasman district and West Coast moving North and Canterbury and Otagomoving South. The Southern Alps have been uplifted on the fault over the last 12 million years in a series of earthquakes. Earthquakes are common along these faults. A transform fault or boundary is where the tectonic motion is primarily horizontal meaning they slide past each other. Two plates sliding past each other forms a transform plate boundary. Two tectonic plates (Oceanic and Continental) collide from compression stress and form a convergent plate boundary. U.S. Department of Commerce, The Northeast Caribbean – Plate Tectonics in Action, Océano Profundo 2018: Exploring Deep-sea Habitats off Puerto Rico and the U.S. Virgin Islands, National Oceanic and Atmospheric Administration. The Marlborough Fault System is a set of four large dextral strike-slip faults and other related structures in the northern part of South Island, New Zealand, which transfer displacement between the mainly transform plate boundary of the Alpine fault and the mainly destructive boundary of the Kermadec Trench, and together form the boundary between the Australian and Pacific Plates. It’s the "on-land" boundary of the Pacific and Australian Plates. It forms a transform boundary between the Pacific Plate and the Indo-Australian Plate. What plate boundary must exist at Alpine Fault? The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone. The Philippine Fault Zone (PFZ) extends 1200 km across the Philippine archipelago behind the convergent boundary of the Philippine Trench and the subduction of the Philippine Sea Plate. Earthquakes along the fault, and the associated earth movements, have formed the Southern Alps. The Alpine Fault is called a strike slip or transform fault.
