PPT-Earthquakes Rocks Move along Faults

An earthquake is a shaking of the ground caused by the sudden movement of large blocks of rock along a fault Earthquakes occur along faults A fault is a fracture or break in Earths lithosphere along which blocks of rock move past each other. 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.. and Folds. The illustration shows an east-west cross section between the Allegheny Structural Front and North Fork Mountain. The topographic feature called Germany Valley sits atop the geologic structure called the Wills Mountain Anticline. Westward directed compressive forces associated with the . (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.. Chapter 2 Section 3. Objectives. F.2.3.1. Explain how a seismograph works.. F.2.3.2. Describe how Geologists monitor faults.. F.2.3.3. . Explain how . seismograph data is used.. The Seismograph. Seismic waves cause the seismographs drum to vibrate but the suspended weight with the pen attached moves very little. Therefore the pen remains still and records the vibrations on the drum.. Rock Deformation. Factors Affecting Deformation. Deformation – refers to all changes in the original shape and/or size of a rock body. . Most plate motion and interactions create force that will cause a rock to deform.. 1. 2. 3. 4. 5. 6. 7. 8. 9. _______________. _______________. _______________. _______________. _______________. _______________. _______________. _______________. _______________. The plate . boundaries. EARTHQUAKES AND FAULTS. Why do earthquakes occur? . What is the relationship between earthquakes and faults? . A shallow MAGNITUDE 7.2 earthquake struck Central . Visayas. Tuesday, October 15. The quake struck at 8:12 am, with EPICENTER 2 kilometers southeast of Carmen, Bohol. The quake's depth of FOCUS was 33 kilometers. According to scientists, the earthquake was caused by movement along the North Bohol Fault. . 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. . Faults are classified by how rocks move.. The blocks of rock along different types of faults move in different directions, depending on the kinds of stress they are under.. There are three types of faults:. 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.. 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.. . What Is an Earthquake?. An . earthquake. is the vibration of Earth produced by the rapid release of energy. Energy released radiates in all directions from its source, the . focus. . Energy is in the form of waves. 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.. 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 .
