but first,let's back up a moment and review what we know about climatic chage in general.First,we defined "climate" as consistent patterns of weather over significant periods of time.
/ a9 s" j0 Q7 i, j7 [ [小马过河-新托福专业备考社区]
0 D% E8 e; i' a8 g4 pIn general,changes in climate occur when the energy balance of the earth is disturbed.Solar energy enters the earth's atmosphere as light and is radiated by the earth's surface as heat.Land,water,and ice each affect this energy exchange differently.The system is so complex that,to date,our best computer models are only crude approximations and are not sophisticated enough to test hypotheses about the causes of climatic change.www.xiaomaguohe.net$ R, {+ C0 U6 S! q2 ^* k& A# Y

& G! @/ v8 i7 a+ p( o  S0 Fof course,that doesn't keep us from speculating.For instance,volcanic activity is one mechanism that might affect climatic change,When large volcanoes erupt,they disperse tons of particles into the upper atmosphere,where the particles then reflect light,Since less light is entering the system of energy exchange,the result would be a cooling of the earth's surface.& @  Q/ R5 M' K% b2 z% k: L
4 ^4 x2 I4 w2 n* u" r; f5 F
of course,this is just one possible mechanism of global climate change.In all probability,a complete explanation would involve several different mechanisms operating at the same time.

Now,you've been reading articles about the tremendous damage done to life and property by earthquakes.That's why seismologists have been working so hard to develop methods of earthquake prediction.We can now predict earthquake fairly well,but the prediction only locate potential areas of dange.They don't predict the specific time and location at which an earthquake is likely to occur.Today I want to introduce to you 3 prediction models that have been developed.

" s  K9 c+ j6 M! z4 l! Z8 A; \小马过河-新托福专业备考社区1st prediction model looks along earthquake faults,those cracks in the earth's crust,to find what are known as seismic gaps.Seismic gaps are places where the fault has shown little or no seismic activity for a long time.This theory postulates that such places are due for a major shock.

2nd models relies on phenomena--like ground tilt.Using long cylindrical tubes containing water,observers noted that ground tilt tended to occur before major earthquakes.that led them to correctly predict the big HAICHENG quake of 1975--the first successful earthquake prediction scientists have ever made.A million people were evacuated from that Chinese city before the earthquake struck.Unfortunately,this method hasn't worked consistently, so we can't say it's been perfected.
