关于地震的20个常识的对错判断,要英语句子.急!
An earthquake is the shaking of the ground caused by an abrupt shift of rock along a fracture in the Earth,called a fault.Within seconds,an earthquake releases stress that has slowly accumulated within the rock,sometimes over hundreds of years.The size of an earthquake is indicated by a number called its magnitude.
Earthquakes have the power to uproot trees and send them crashing into buildings.They can trigger landslides and avalanches,and cause flooding and tsunamis.Human structures are also at risk.It is interesting to note that tall buildings will sustain the least damage if they are located directly at the epicenter.This is because they can withstand the up-and-down motion of P-waves.S-waves,on the other hand,occur far away from the epicenter,and cause the greatest stress by shaking buildings from side to side.These buildings are often knocked off their foundations.
Scientists are continuously thinking of ways to try and reduce earthquake power.Some are trying to lessen the friction between colliding plates.They poured water down a fault where two plates were grinding together.The water “lubricated” the fault,letting one piece jerk free with a number of little earthquakes and preventing a large tremor.Architects are also designing earthquake-proof buildings,constructing on rock instead of gravel,or on soft sand or clay.Researchers are always trying to reduce the impact of earthquakes.They continue to study and experiment with ways to tame the Earth.However,we all still have much more to learn before we can control the power of one of nature’s most amazing phenomena.
