Earthquakes And Tsunamis

Buildings on smooth and mud Because much of San Francisco sits on a landfill, the smoothen and mud in the area can advantageously liquefy. When an temblor hits, the keystone and mud trap the water. As the backbone particles go forward to a denser arrangement, it pushes on the water and increases the water pressure. evidence this rule by putting several inches of sand in a bring. Fill the pan with water until it is most to the top of the sand. pull a brick upright in the sand. tear 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 epicenter of the temblor. 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. swan the point of the compass in the city where the machine is and fabricate a complete muc kle 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 dickens slabs of clay. Place them on two side-by-side sheets of plastic foam. Use dark-skinned clay and build a little town on the clay. Include items like a road, house and turn over line.

Hold one piece of plastic foam heavy(p) and push the second piece with one quick motion. chitchat the items on top of the clay for damage caused by the earthquake. This piece of work can lead to a discussion of earthquake damage. measure machine Tectonics To begins to ex! plain 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 apart. Conservative plates, like the San Andreas fault, slide previous(prenominal) each other ...If you want to get a unspoiled essay, order it on our website: OrderCustomPaper.com
