DynamicsOnline version Seismology by keerthana sakthi 1 Earthquakes occur when there is a sudden release of stored up energy in Earth's a Inner core b Outer Core c upper mantle d lower crust 2 Termors that have occured in Earth's crust are known as a Volcanic eruptios b volcanno earthquake c Earthquake d bed eruptions 3 Instrument to measure Earthquake is a Quakemeter b seismogram c seismograph d Typanicgraph 4 Tremendous damage along with the huge destruction of buildings can take at a scale of a 7 b 5 c 6 d 10 5 Another name of Earthquake a Nektons b Flickers c Temblors d Blusters 6 After Earthquake has taken place, it is followed by a Proschoks b Preschoks c Afterschoks d Minimaxial shocks 7 seismograph is dependant on extend of damage caused by a Earthquake b air barrier c volcano d Explosion 8 Magnitude of energy released by an earthquake is caused by a Temblor scale b Richter scale c Tectonic scale d MMI scale 9 At intensity level of 1 a poor buildings shake b people dont feel earthquake c buildings & bridges collapse d people feel the tremor & windoe rattle 10 Furniture may move and people may run outside houses at a scale of a 3 b 4 c 5 d 2 11 Richter scale measures facctor of a 2 b 5 c 10 d 7 12 Objects fall from shelves, plaster walls get cracked and people feel tremor at a level of a 6 b 3 c 5 d 4 13 other than boundaries of crustal plates, earthquakes may occur within areas with a frequent civil activities b frequent explosive activities c frequent deforestation activities d frequent volcanic activities 14 on a Richter scale, a '6' means tremor is 10 times greater than a scale of a 3 b 4 c 5 d 2 15 Earthquake is not noticable to a scale of a 3 b 2 c 4 d 5 16 Greater magnitude, the a lesser the amount of energy released b greater the amount of energy released c lesser the amount of energy absorbed d greater the amount of enegry absorbed 17 At intensity level of 6 a poor buildings shake b people dont feel earthquake c buildings & bridges collapse d people feel the tremor & windoe rattle
