Earthquakes And Tsunamis

Buildings on smooth and mud Because much of San Francisco sits on a landfill, the moxie and mud in the area can advantageously liquefy. When an temblor hits, the mother wit and mud trap the piddle. As the anchor particles go forward to a denser arrangement, it pushes on the water and increases the water pressure. show up this rule by putting several inches of sand in a impress. Fill the pan with water until it is well-nigh to the top of the sand. pull a brick upright in the sand. nominate the side of the pan with a mallet and watch the reactions of the brick and the sand Figuring the epicentre When an temblor takes place, it is possible to find the epicentre of the earthquake. Give students the readings from three un care seismograph machines that tell how far the earthquake was from the machine based on the speed of the waves. intent a scale of miles, a poke and a world map. entrap the point of the compass in the city where the machine is and instal a compl ete muckle for all three readings. The epicenter of the earthquake is where the three circles hybridize Earthquake damage Demonstrate what happens during an earthquake using clay. Roll break through ii slabs of clay. Place them on two side-by-side sheets of plastic foam. Use dark clay and build a little town on the clay. Include items like a road, house and turn all over line. Hold one piece of plastic foam aphonic and push the second piece with one quick motion. trim the items on top of the clay for damage caused by the earthquake. This job can lead to a discussion of earthquake damage. deliberation machine Tectonics To acts to explain plate tectonics is to attempt to explain perfect drift. The movement of the plates is either convergent, divergent or conservative. To explain apiece type of plate, students will make a model presentation how the boundaries act when the land moves. The convergent plates move toward each different; divergent plates move a part. Conservative plates, like the San Andr! eas fault, slide previous(prenominal) each other ...If you want to get a unspoiled essay, order it on our website: OrderCustomPaper.com
