To complete this lab, you will conduct the following types of observations, measurements or calculations, following the calculations and graphs standards read, draw, and interpret maps of the earth examine, construct, and interpret diagrams, flow charts, and tables of information. By contrast, other subduction zones produce major earthquakes occasionally and minor ones all the time: magnitude 50, magnitude 40, magnitude why are the neighbors moving their sofa at midnight. In this exercise, the students will examine the pattern of earthquakes and volcanoes at occur in the atlantic ocean most of these occur at the diverging plate boundary that. A steeper angle along a subduction zone most earthquakes occur at tectonic plate boundaries figure 1 an earthquake can be classified by the depth of its focus deep-focus earthquakes have foci at more than 300 km, shallow-focus earthquakes have a focus at less than 70 km, and intermediate-focus earthquakes investigation lab 172.
But cascadia subduction zone earthquakes are completely different—and will trigger massive destruction from british columbia to california and produce tsunamis that can wipe entire towns off the. Bfk--modeling convection currents lab report 2013tectonicsofindonesia_lecture2 continental drift 7th grade specification mona ar dika 2015 related literature this action is the reason why the strongest earthquakes occur in subduction zones hence, the philippines is an earthquake-prone area do you know the ring of fire. Subduction zones are responsible for many of earth's most extreme natural events including earthquakes, volcanic eruptions, and tsunamis these hazards coupled with increasing population density in these regions leads to an urgent need to understand how subduction zones work to better inform hazard assessment, mitigation, forecasting, and early.
Abstract subduction zones are home to the most seismically active faults on the planet the shallow megathrust interfaces of subduction zones host our largest earthquakes and are likely the only faults capable of magnitude 9+ ruptures. Earthquake seismology is an important constraint on the geometry of subduction zones now that we've looked at the raw earthquake data, we will load a model of slab geometry based on the seismic data. 10c explain how plate tectonics accounts for geologic processes and features, including sea floor spreading, ocean ridges and rift valleys, subduction zones, earthquakes, volcanoes, mountain ranges, hot spots, and hydrothermal vents.
Subduction plate boundaries are home to the world’s largest-magnitude earthquakes and can generate tsunamis with catastrophic effects on populated coastal regions, like what occurred in 2004 in. Write a lab report summarizing your work on the features of convergent plate boundaries review your work on subduction zone features from lab 3, volcanoes from lab 6 and earthquakes from lab 8. Subduction zones are some of the most seismically active areas on earth earthquakes in these spots that occur close to the surface can be devastating, like the one that struck japan in 2011. Lab: earthquake depths at subduction zones by charles burrows background: subduction zone most earthquakes occur at tectonic plate boundaries an earthquake can be classified by the depth of its focus (where it originates) deep-focus earthquakes have foci at more than 300 km, shallow-focus earthquakes have.
Lab report uploaded by chari99 pages 26 st louis, mo and memphis, tn b) explain why the mississippi valley region, despite experiencing large magnitude earthquakes in the early 1800s, and northern california coast all face the prospect of a major subduction zone earthquake that generates a series of large tsunami waves. An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the earth, resulting from the sudden release of energy in the earth's lithosphere that creates seismic wavesearthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend several characteristics of subduction zone earthquakes.
Students will perform an edible plate tectonics lab and start their graphic organizer island arcs, and subduction zones divergent boundaries create rift valleys, mid ocean ridges, islands, and volcanoes transform boundaries create fault zones and earthquakes earth has 4 main layers: crust, mantel, outer core, and inner core the outer. Slow earthquakes occur continuously in the alaska-aleutian subduction zone study reports nearly continuous tremor and 1,300 low frequency earthquakes in this region.
Research may explain earthquakes in subduction zones the mineral lawsonite undergoes brittle failure at high temperature and pressure, as evidenced by the cracks seen in this image that brittleness could trigger earthquakes in subduction zones where lawsonite is present. The subduction process begins at the sunda trench a few dozen miles offshore of the islands from there the plate vanishes at a steep angle with earthquake locations becoming deeper and deeper to the north as the plate subducts. This report describes how to build a model of the outer 300 km (180 miles) of the earth that can be used to develop a better understanding of the principal features of plate tectonics, including sea-floor spreading, the pattern of magnetic stripes frozen into the sea floor, transform faulting, thrust faulting, subduction, and volcanism.
