What Is an Earthquake? An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. 2 Introduction • Earthquakes represent the vibration of Earth because of movements on faults.

Explains how energy is stored in rocks Rocks bend until the strength of the rock is exceeded Rupture occurs and the rocks quickly rebound to an undeformed shape Energy is released in waves that radiate outward from the fault The Focus and Epicenter of an Earthquake The point within Earth where faulting begins is the focus, or hypocenter The . During these earthquakes, the affected part of earth's surface shakes violently. Faults may range in length from a few millimeters to thousands of kilometers. Some of the worksheets for this .

Faults allow the blocks to move relative to each other. . There are 37 words. Earth and Space. Sudden movements in faults cause earthquakes. Vibrations (earthquakes) occur as the deformed rock "springs back" to its original shape (elastic rebound). A seismograph is an instrument that measures the size and strength of the seismic waves that are released during an earthquake. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move . earthquake starts. Fault planes may contain striations or slickensides that can indicate the direction of fault motion . When an earthquake occurs on a fault, the rock on one side of the fault slips with respect to the other. N. W E SCIENCE S GRADE 8 QUARTER 2. Word Document File.

If there is an earthquake, there is a fault. • Earthquake - vibration of Earth due to rapid release of energy • Plate - rigid section of the lithosphere that moves as a unit • Epicenter - the point on the earth's surface vertically above the focus of an earthquake. answer choices. The stress from an earthquake pushes out, away from the fault line. 3. Earthquakes most often occur along existing faults whenever the frictional forces on the fault surfaces are overcome. %PDF-1.5 Earthquakes and faults (Grade 8 Lesson) 1. A fault is a fracture or zone of fractures between two blocks of rock. where a rock under stress breaks. The Rio Grande Valley in New Mexico is an example of a normal fault. • The Australian Geological Survey Organisation in Canberra estimates that, on average, the Australian region experiences an earthquake of at least Richter scale magnitude 5.5, or larger, every 13-15 months.

Which of the following is the reason why mountain exists? Protection Against Earthquakes • Ninety per cent of all earthquakes in the world take place at tectonic plate boundaries and are the result of the constant movement of the plates against each other.

The classic example of a right-lateral strike-slip fault is the San Andreas fault while They also offer hands on activities to help those tactile learners in your classroom. But in this case, the stress from an earthquake pushes in toward the fault line. Such earthquakes can destroy entire cities and villages causing a great loss of life and property. Students may not have a personal experience with earthquakes. The earthquake with the highest Richter scale reading ever took place in 1960, in Valdivia, Chile. This video discusses about Earthquakes and Faults. *As tectonic plates move, they cause stress in the crust, which in turn produces faults and . mountains and faults) in terms of plate tectonics. The fault plane in this diagram is the area of contact between the two fault blocks. STRESS -- is a force that squeezes rocks together, stretches or pulls them apart, or pushes them in different directions. Learning Area. Unlocking of terms: • Fault - is a break in the Earth's crust, and along the break which movement has occurred. Perfectly Periodic In this model an earthquake always happens when the stress level reaches the same high value and during the earthquake the stress always drops to the same low value. Playing educational quizzes is a fabulous way to learn if you are in the 6th, 7th or 8th grade - aged 11 to 14. 10.20. GradPoint. The rocks are folded. • United State Geological Survey (USGS) defines it as a "fracture along which the blocks of crust on either side have moved relative to one another parallel to the fracture.
