The Pacific Plate is pushed west and sinks back into the mantle along a "subduction zone" as it reaches the Indo-Australian plate and the smaller Tonga Plate. Tonga Trench. The oceanic plates form at the divergent plate boundaries mainly around the mid-ocean ridges . tonga trench animals. Thanks to plate tectonics and the relentless push of the Pacific plate into the Tonga Trench, the islands of Tonga are literally being lifted out of the water. Trenches are long, narrow depressions on the seafloor that form at the boundary of tectonic plates where one plate is pushed, or subducts, beneath another. 2 Which tectonic plate is being subducted at the Tonga trench And at the Chile from HISTORY 206 at Hilton High School.

The Tonga Ridge rises above the Tonga Trench with depths of 10 km on the east and . (Gatliff, 1990). The heavier oceanic plate subducts beneath the lighter continental plate forming a trench. The plate flexure and normal faulting characteristics along the Tonga, Japan, Izu-Bonin and Mariana Trenches are investigated by combining observations and modeling of elastoplastic deformation of the subducting plate. The Tonga Trench is the deepest point in the southern hemisphere and the second-deepest point on Earth after the Mariana Trench. . The Aleutian Trench is formed where the Pacific plate subducts beneath the North American plate in the Arctic region between the U.S. state of Alaska and the Russian region of Siberia. Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries.Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. The Tonga Trench has a steeper profile than the Peru-Chile Trench. Trenches mark subduction zones. 10,882 m (35,702 ft) Philippine Trench. It is one of a series of such features along the Tonga-Kermadec volcanic arc - formed as part of the 'Ring of Fire', or the circum-Pacific belt. This formed the trench.

This area has been studied by ships of Scripps Institution of Oceanography (SIO), commencing with research vessels "Horizon" and "Spencer F. Baird" in 1952. When crust is formed at a mid-ocean ridge, it is hot and buoyant meaning it has a low density. Where two tectonic plates converge, if one or both of the plates is an oceanic lithosphere, a subduction zone will form. Tonga lies at the easternmost edge of the Indo-Australian Plate (Fig. This is commonly a process of plate tectonics. They were created from the subduction of the western-moving Pacific plate under the Australia-India plate at the Tonga Trench. Fiji therefore represent a portion of the old Vityaz Arc which was split up, and rotated clockwise to its present position. A region where this process occurs is known as a subduction zone, and its . The Tonga Trench. The Kermadec plate comprises of the northeastern part of New Zealand, and it extends north all the way to the southern part of the Tonga plate. When two plates crash into each other, an . Deep trenches are often formed where tectonic plates are being subducted and earthquakes are common. Earth's crust is made up of comparably thin plates that "float" on the molten rock of the planet's mantle. The . History: Named from the nearby Tonga Archipelago. . Ocean trenches are deep sections of the ocean where an oceanic plate is usually sinking below a continental plate. The Earth's lithosphere is divided into 17 large tectonic plates and about 20 smaller plates, all of which are continuously moving with respect to each other. 18-1) and is part of an arc system (the Tonga Ridge, Scholl and Vallier, 1985) that has formed in response to subduction of the Pacific Plate over a period of at least 45 m.y. This is the site of. . Pacific Plate under the Indo- Australian Plate at the Tonga trench. . Summary of Data As two tectonic plates converge, if one or both of the plates is an oceanic lithosphere, a subduction zone will form. They are formed in the subduction zone as the denser oceanic plate is subjected under the continental plate. There is an active volcanic arc in the area . The trench lies at the northern end of the Kermadec-Tonga Subduction Zone, an active subduction zone where the Pacific Plate is being subducted below the Tonga Plate and the Indo-Australian Plate. Most of the hydrous minerals become unstable and break down 40 to 100 miles beneath the surface, releasing a lot of water that triggers intermediate-depth earthquakes. To the West it is bounded by a spreading center with the Australian plate. a. Subducting plate is to the east and overriding plate is to the west b. Subducting plate is to the west and overriding plate is; Question: 8. Tonga Trench. The Pacific Plate picks up water near the trench, when the slab cracks, and seawater reacts with the rock to form hydrous minerals. The lithosphere is the upper layer of the mantel and consists of the tectonic plates. 26°S) the Tonga Trench is colliding with the Louisville Seamount Chain, a chain of guyots and seamounts on the Pacific Plate roughly parallel to the Hawaiian-Emperor seamount chain in the northern pacific.

In this case, the edge of the Pacific plate was forced under the Tonga plate, a process still going on today. The South Sandwich Trench. Pacific Ocean. With a depth of 10.54 kilometers below sea level, Philippine Trench, also known as Philippine Deep, is the world's third deepest point in the ocean. Researchers have also found that these plate movements also cause large volcanoes in the Japan trench as well as the Mariana trench.
