Convergent boundaries exist along the north between the Bird's Head and the Caroline Plate, the Philippine Sea Plate, and the Halmahera Plate to the northwest.Back-arc basins were initially a surprising result for plate tectonics theorists, who expected convergent boundaries to be zones of compression, rather than major extension.This oblique convergent boundary instigated a clockwise rotation of the Macquarie Ridge Complex forming the Hjort Trench and numerous fracture zones around the Macquarie Ridge Complex.The eastern margin is a convergent boundary subduction zone under the South American Plate and the Andes Mountains, forming the Peru Chile Trench.The Sevier orogeny was the result of convergent boundary tectonic activity between approximately 140 million years ( Ma ) ago and 50 Ma.The northern side is a convergent boundary subducting under the North American Plate forming the Aleutian Trench and the corresponding Aleutian Islands.Earthquakes at this depth of focus typically occur at oceanic-continental convergent boundaries, along Wadati-Benioff zones.The island arc is formed at the convergent boundary where the Pacific Plate subducts under the Indo-Australian Plate.The northern and western borders are a divergent boundary while the rest of the borders are transform and convergent boundaries.It's difficult to see convergent boundaries in a sentence.This convergent boundary has a rate of subduction of approximately 5.5-7.4 cm / yr.BIFs are typically found in intra-oceanic, arc or forearc settings, which are associated with convergent boundaries.As the tectonic plates migrate, oceanic crust is subducted under the leading edges of the plates at convergent boundaries.The Nankai Trough is a convergent boundary where the Philippine Sea Plate is being subducted beneath the Eurasian Plate.Another convergent boundary exists between the Bird's Head and the Banda Sea Plate to the south.The easterly side is a convergent boundary subducting under the North American Plate in northern California.Convergent boundaries create foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure.Plate collision can produce earthquake, volcanoes, mountains formation, and other geological event.
Eugeosynclines often contain flysch typical of a continental-continental convergent boundary. A convergent plate boundary is the boundary that occur when two plates collide each other either a continental plate with continental plate or oceanic plate.The westerly side is a convergent boundary with the subducting Nazca Plate.But there is no convergent boundary within the North American Plate!.The Andes are the longest mountain range in the world! The andes are found in Peru, Bolivia and Ecuador. The andes are almost 7,000 km (4,400 miles) over Argentina and Chile. Some of the volcanoes are still active and smoke sometimes. The Nazca plate subducted under the South American plate. The andes were formed when the Nazca and South American plate collided about 45 million years ago. The Andes are a mountain range of volcanos and of course, mountains. When the oceanic plate slides under the continental plate it can also make a trench. Water does not like being under pressure and so it leaves the rocks and goes up to the other rocks above and helps them melt into magma. As the plate sinks, sediments and water comes down with it. The denser plate, which is always oceanic, sinks under the the continental plate. An oceanic continental convergent boundary is where oceanic and continental tectonic plates collide.
