PPT-Faults, Earthquakes and Uplift

Move it move it What are they Fault a break or fracture in the crust of Earth Earthquakes shaking or trembling of the earth caused by movement along a fault Uplift upward movement of Earths crust. Deformation. Whether a material bends or breaks depends on . h. ow much stress is applied to the material.. Deformation. Process by which the shape of a rock changes because of stress.. Objectives:. Describe. Regional Strain. Types of Fault and the Principal Stresses. Fault Rocks. Gouge: non-cohesive, fine grained. Breccia: coarse angular fragments. Cataclasite: cohesive fragments. Fault Melt (pseudotachylite):. The Earths crust . The earths crust is in constant motion.. Volcanoes and earthquakes arise as sections of crust push . toghether. or pulled apart. Volcanoes and earthquakes are more common in certain parts of the world. By monitoring ground vibrations scientists can sometimes. (pages 178–183). The Seismograph (page 179). Key Concept: Seismic waves cause the seismograph’s drum to vibrate. But the suspended weight with the pen attached moves very little. Therefore, the pen stays in place and records the drum’s vibrations.. 2015-2016. Rationale. As educators, it is one of our greatest hopes that our scholars grow up to be independent, problem solving, well rounded. , . lifelong . learners. . Science Fair can be a powerful and effective means to achieving this end. The evident purpose of Science Fair is for scholars to experience the Scientific Method firsthand by generating a question of interest, designing the experiment, collecting and analyzing data, and synthesizing a conclusion. The benefits don’t end here. By scholars investigating real world issues, they become . Earthquake. – shaking and trebling that results from the movement of rock beneath Earth’s surface.. Plate movement causes earthquakes from stress and faults in Earth’s crust. When the rock breaks earthquakes happen. Earth’s Dynamic Crust. Original Horizontality (law of superposition):. Assumption . that sedimentary/igneous rocks form in horizontal layers . Deformity. Folded: Layers are bent/curved. Deformity. Miles P. Wilson. Gillian R. Foulger, Jon G. . Gluyas. , Richard J. Davies & Bruce R. Julian. British Seismology Meeting. 5. th-. 7. th. April 2017. 1. Disclaimer and terminology. Study background. Earthquakes result from sudden motions along breaks in Earth’s crust and can affect landforms and societies.. An entire branch of Earth science, called . seismology. , is devoted to studying earthquakes.. ITET G. . MAGGIOLINI . & . “The green . school. network. ” . present. . What. . is. an . earthquake. ?. An earthquake (also known as a quake, . tremor) . is the . shaking of the surface. of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. . Move it, move it !!. What are they?. Fault: a break or fracture in the crust of Earth.. Earthquakes: shaking or trembling of the earth caused by movement along a fault.. Uplift: upward movement of Earth’s crust.. This topic will shake you up. Stress. Stress-. a force (energy) that acts on rock to change its shape or volume. Types of Stress. Tension-. pulls or stretches rock so that it becomes thinner in the middle. This happens at divergent plate boundaries.. Content Purpose:. Explore the scientific theory of plate tectonics by describing how the movement of Earth's crustal plates causes both slow and rapid changes in Earth's surface, including volcanic eruptions, earthquakes, and mountain building. . During: Fault notes. After: Exit slip 4 questions. Day 1: Faults. Fault-. a breaks . in the earth’s surface along which rocks can . move.. Three . kinds of faults – determined by how the rocks move against each .
