H., 1979, Submarine thermal springs on the Galapagos Rift: Science, v. 203, p. 107321083. Student exploration plate tectonics answer key.com. As it turns out, current scientific knowledge reveals convection is one of the major forces in driving plate movements, along with gravity and density. While seemingly occurring at random, rifting is dictated by two factors. In places where the continental plates are very thick, they reflect so much heat back into the mantle it develops strong convection currents that push super-heated mantle material up against the overlying plate, softening it. In general, the Earth can be divided into layers based on chemical composition and physical characteristics. Observe: Boundary B is an example of a convergent boundary, where two plates are moving toward one another.
Seismic waves are produced when some form of energy stored in Earth's crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and "slip. " Paleomagnetism is the study of magnetic fields frozen within rocks, basically a fossilized compass. This information—along with other evidence gathered from rock ages, vegetation types, and island size—indicates the oldest islands in the chain are located the furthest away from the active hotspot. Student exploration plate tectonics answer key worksheet. The continental lithosphere is of lower density and thus more buoyant than the underlying asthenosphere.
You can get your money back within 14 days without reason. For example, when a plate travels near an oceanic plate, a zone called the subducted slab, the crust below is pulled downward and the crust above remains undisturbed. Little was understood about earthquakes until the emergence of seismology at the beginning of the 20th century. Explain transform boundaries as places where adjacent plates shear past each other. Gizmo of the Week: Plate Tectonics. Course Hero member to access this document. In two divergent plates. Because it is so important in understanding how the world works, plate tectonics is the first topic of discussion in this textbook.
1016/0016-7037(66)90007-X. When a plate tectonic plate moves, the crust underneath it shifts, causing the crust on top of the plate to be pulled downward, causing that part of the crust to become less dense. By Tanya Atwater and John Iwerks. Stich, D., Mancilla, F. de L., Pondrelli, S., and Morales, J., 2007, Source analysis of the February 12th 2007, Mw 6. 1130/0016-7606(1970)81[3513:IOPTFT]2. ;2. Student exploration plate tectonics answer key 2020. These seams with little or no tectonic activity are called failed rift arms.
The mechanism behind how supercontinents are created is still largely a mystery. If the extension activity is extensive and deep enough, a backarc basin can develop into a continental rifting zone. Scientists identify this zone by changes in seismic velocity and sometimes physical barriers to movement. Some well-known examples include the Tahiti Islands, Afar Triangle, Easter Island, Iceland, Galapagos Islands, and Samoan Islands. J. Tuzo Wilson was the first scientist to put the entire picture together by proposing the opening and closing of the ocean basins. The base of the crust is characterized by a large increase in seismic velocity, which measures how fast earthquake waves travel through solid matter. Other types of faults—normal and reverse —tend to be more destructive, obscuring or destroying these features. Extensional back-arc faults pull rocks and chunks of plates apart. Xenoliths are carried within magma and brought to the Earth's surface by volcanic eruptions. The boundaries of oceanic-oceanic subduction zones show very different activity from those involving oceanic-continental plates. When the descending slab subducts at a low angle, there is more contact between the slab and the overlying continental plate than in a typical subduction zone. B., 2011, Slab fragmentation, edge flow and the origin of the Yellowstone hotspot track: Earth Planet. Satake, K., and Atwater, B. F., 2007, Long-term perspectives on giant earthquakes and tsunamis at subduction zones*: Annu.
Initially, scientists thought the ridge was part of a mechanism that explained the expanding Earth or ocean-basin growth hypotheses. B., Pinkerton, H., Norton, G. E., and Pyle, D. M., 1990, Physicochemical properties of alkali carbonatite lavas:Data from the 1988 eruption of Oldoinyo Lengai, Tanzania: Geology, v. 18, no. A second belt, known as the Alpide Belt, passes through the Mediterranean region eastward through Asia and joins the Circum-Pacific Belt in the East Indies. Most xenoliths are made of peridotite, an ultramafic class of igneous rock (see chapter 4. Eventually, as ocean basins close, continents join together to form a massive accumulation of continents called a supercontinent, a process that has taken place in ~500 million-year-old cycles over the earth's history. Note that because the motion of the plates is not exactly parallel to the fault, it causes divergent motion in the interior of North America. Lehmann, I., 1936, P', Publ: Bur.
The core of the Earth has both liquid and solid layers and consists mostly of iron, nickel, and possibly some oxygen. Instead of one plate descending beneath another, the two masses of continental lithosphere slam together in a process known as a collision. Some scientists have proposed a subduction mechanism called oceanic slab rollback that creates extension faults in the overriding plates. The deeper parts of the crust are subjected to higher temperatures and pressure, which makes them more ductile.
The Wasatch Fault, which also created the Wasatch Mountain Range in the state of Utah, forms the eastern divergent boundary of this broad rift (Animation 1 and Animation 2). Help with many parts of the process by dragging pollen grains to the stigma, dragging sperm to the ovules, and removing petals as the fruit begins to grow. Question 2 Correct Mark 100 out of 100 Flag question Question text What does the. Inner and Outer Core. Hagstrum, J. T., 2005, Antipodal hotspots and bipolar catastrophes: Were oceanic large-body impacts the cause?
Rifting does not occur in continents with older and more stable interiors, known as cratons. This is called back-arc faulting. What made these features unusual was the north and south magnetic poles within each stripe were reversed in alternating rows. These forces build up around the area of the bend, where the opposing plates are restricted from sliding past each other. In turn, the higher mantle material beneath the subducted slab gets dragged upward by this movement of the crust, causing the entire Earth's surface to rise and fall by 6 centimeters per year. 11, p. 2013JB010466. The seafloor was also mapped magnetically. The theory of plate tectonics states the surface layer of the Earth is broken into a network of solid, relatively brittle plates. Where on Earth can you find this type of boundary? The surface of the crust is relatively brittle.
Turn on Boundary name, and click on each boundary. Wegener found similar evidence when he discovered tropical plant fossils in the frozen region of the Arctic Circle. McKenzie, D. P., and Parker, R. L., 1967, The North Pacific: an Example of Tectonics on a Sphere: Nature, v. 216, p. The energy can be released by elastic strain, gravity, chemical reactions, or even the motion of massive bodies. Some images used in this set are licensed under the Creative Commons through. Other pro-continental drift followers used expansion, contraction, or even the moon's origin to explain how the continents moved. In an attempt to map the Hawaiian mantle plume as far down as the lower mantle, scientists have used tomography, a type of three-dimensional seismic imaging. The mesosphere, sometimes known as the lower mantle, is more rigid and immobile than the asthenosphere.
It helped me a lot to clear my final semester exams. Search for another form here. Identify divergent boundaries, including rifts and mid-ocean ridges, as places where plates separate. Eventually, scientists realized adding the idea of continental movement explained the data better than pole movement alone. Forsyth, D. W., 1975, The Early Structural Evolution and Anisotropy of the Oceanic Upper Mantle: Geophys. Geologists now have evidence that continental plates have been continuously converging into supercontinents and splitting into smaller basin-separated continents throughout Earth's existence, calling this process the supercontinent cycle, a process that takes place in approximately 500 million years. A third idea, gravitational sliding, attributes the movement to gravitational forces pulling the lithospheric plates down from the elevated mid-ocean ridges and across the underlying asthenosphere.
White, I. C., and Moreira, C., 1908, Commissão de estudos das minas de Carvão de Pedra do Brazil: - de Wijs, G. A., Kresse, G., Vočadlo, L., Dobson, D., Alfè, D., Gillan, M. D., 1998, The viscosity of liquid iron at the physical conditions of the Earth's core: Nature, v. 392, no. Some explained this away as part of the normal movement of earth's magnetic north pole.
