W:I think you would [color=red]have[/color] enjoy my geology class this morning .G'u3EeF5r7w
M;Don't bet on it I 've [color=red]never[/color] cared much about [/size][size=3][color=red]rocks

R6VR3H9yC [/color]W:But you do care about[b] dinosaurs[/b] I[color=red] recall[/color] and today we discuss the geological evidence about what may have kill off the dinosaurs at least [color=red]here in[/color] Norht America
r8ONy2q` M:Oh sure .They got hit by a comet or something I think mU `7U$?`X3|,S2v
W:Well Yeah about 60 million years ago a huge comet [color=red]did crash into[/color] earth down in Mexico and it [color=red]plowed [/color]out [color=red]as an enormous crater[/color] over a hundred miles cross
5gSm%d%Q M:And that what why death the dinosaurs [/size][size=3][color=red]right ?#tGO;yWM(J'l~
[/color]W:Well it wasn't exactly the [color=red]impact[/color] itself but what happend [color=red]right afterward , you see[/color] researchers figured out from the [color=red]shape of[/color] the crater that the [color=red]comet [/color]must be coming in[color=red] pretty[/color] low across the [color=red]Atlantic[/color] and so right after the impact a huge cloud of [color=red]fire river[/color] must have[color=red] sweep[/color] clear across the morth America all in just a few minutes .And that [color=red]what [/color]probobaly kill off not [color=red]just[/color] the dinosaurs but a lot of different species of plants and animal !h)b.v-l)a/l;s
M:Amazing !Jn+\{8{^g%XQ#S
W:Yeah ![color=red]And even[/color] 2000miles from the impact plant [color=red]have been burst in the flames[/color]
tx!m6?(N7eaAH M:And the fire [color=red]that intense[/color] muat destroy[color=red] just about[/color] everything !{UDpS
W:Well above ground anywayvDnm-_a+l)ka
M:Above ground ?Say!Iwonder[color=red] if it that explains[/color] why the dinosaurs all disppeared [color=red]but [/color]some other animals like may be small living underground manage to survive
/^aV;L)h W:Make sense .Any how later on the[color=red] tons of dusts that thrown away[/color] [color=red]out into the atmosphere[/color] may have caused some global[color=red] climate[/color] change .So [color=red]eventually [/color]the comet probably affected plants and animals species all around the world but [color=red]nowhere as[/color] much[color=red] as[/color] North America .[/size]

We've talking about[color=red] some of effects[/color] that the human being [color=red]so act[/color] on the earth .One that you may not be awared [color=red]of is[/color] that we've actually begun to change the length of the day .The other we say that one day [color=red]is the amount of [/color][color=black]time[/color] the earth[color=red] need to suspend[/color] completely around on[color=red] axis[/color] .And the [color=red]imagery [/color]line[color=red] run[/color] through the [color=red]center[/color] of the earth from north to [color=red]south[/color] .And of course there are a lot of [color=red]physical causes[/color] that can affect the [color=red]spin of[/color] the earth[color=darkred] rotation[/color] but there is only one that can direct result of human activity .since 1950 human being have built about ten thousand amount of the earth water when resevirs have [color=red]redistributed[/color] tremendous [color=red]amount of t[/color]he earth water[color=red] when[/color][color=red] they[/color] are used to be in the area near the equator and the imagery [color=red]line on surround the middle[/color] of the earth is now the reservoris in the area of different [color=red]latitude[/color] .The latitude matters because well think [color=red]of[/color] the earth and its axis the equator[color=red] contains[/color] the areaa in the earth that are the farthest way [color=red]from [/color]axist .So water has been redistributed from the[color=red] equator[/color] reasons then whatever the water id ,it's close to the earth axis ,[color=red][color=black]It's like [/color]when ice skaters perform spins[/color] when those skater put their arm enclose to theri boday they [color=red]spin [/color]faster .So the earth is spinning faster because the reservoirs have redistributed the water closer to [color=red]its axist[/color] .And because the earth in spinning fast since 1950 the length of day has [color=red]decreased [/color]by about 8 million[color=red]th of a[/color] second．   I know that [color=red]don't sound like[/color] much but significant in that this is the first time that human beings have ever had [color=red]miserable [/color]affect on the earth motion.[/size]

`+i^d.zD First of all let's look at why temperature [color=red]tend to be[/color] highter in city than in the rural area .This happens because almost 50 percent of[color=red] the urbam area are comprised of[/color] hard [color=red]surfaces [/color]like paved street parking[color=red] lot[/color] buildings and[color=red] roof[/color] tops .As the result any amount of rainfall is quickly repelled [color=red]by this service and carry away by[/color] storm [color=red]drains and gutters[/color].[color=red]Especially[/color] water[color=red] just[/color] doesn't have [color=red]the chance to stand[/color] around [color=red]until [/color]evaporate and during the process of the evaperation that heat is remove from the air .So in the cities where there is less evaperation temperature will be highter and [color=red]of course[/color] there are also be issue of [color=red]added [/color]heat coming from building [color=red]heating[/color] systerm from [color=red]industry [/color],cars and[color=red] even[/color] humans body .Even [color=red]we being in t[/color]he city [color=red]iteself [/color]temperature can vary significantly .For example on winter streets that get alot of use will be 2 or 3 degree [color=red]warmer[/color] than [color=red]less[/color] travel streets. In place [color=red]where car sits for a while[/color] like a stop[color=red]light [/color]can be in another 3 degree warmer .On the other hand low [color=red]spot[/color] in the city where cold [color=red]air[/color] collect will be much colder than highter places .Rain and snowfall are also affected by [color=red]urbanization .[/color]Cities[color=red] tend to get quitely[/color] less snowfall than the surrouding factors .First the warmer city temperature second the lager number of dust particle in the urban [color=red]air[/color] .It [color=red]seems[/color] dust particles are important requirement for condensation .The water [color=red]vapor in the atmosphere[/color] is zble to change to liquid by [color=red]planning[/color] to dust particles suspended in the air 。So where [color=red]there [/color]is the highter number of dust particles[color=red] condensation[/color] take place more [color=red]easily [/color].That why fogs and clouds are usually more frequently around the city .Once condensation takes place ,the rainfall is not far behand .In the London area for example [color=red]thunder[/color]storms can produce 30percent more rainfall than the surrounding countryside .Some urban climatologist go so far as they argue that they can see a pattern increasing the rainfall during the workweek .Tehy belive rainfall amounts are small around the weelen because the dust particle generated by cars and factories are[color=red] reduced .[/color] [/size]

I often hear my friends say that the days pass much more quickly than they used to be .But geologically speaking just the opposite is true .In fact a complete day which now lasts 24 hours actually used to be much shorter only about 18.How do we know that ? Because of a number of [color=red]finally strata[/color] rocks like these .Rock form belong ancient shortlines almost[color=red] billion[/color] years ago .They tiny lines of these samples show [color=red]us [/color]layer of [color=red]light [/color]and dark form by [color=red]dusk blown[/color] over the shortline from the [color=red]landsite .Alternating was the mud and sand deposited（听得极度不爽）[/color] by the [color=red]waves [/color].So the space between [color=red]on monthly[/color] high tide and the next .And very in [color=red]fitness [/color]of layers show us the [color=red]circle[/color] of the season as well .Together the data indicate there were fewer months for year way[color=red] back then[/color] .That means that the moon was moving more slowly than as[color=red] it[/color] revolved [color=red]around [/color]the earth .So what[color=red] caused[/color] the moon [color=red]do [/color]speed up so much over last billion years ?It muat be the tides think about it .As the [b]gravity[/b] of the moon pulls on the oceans to form the tides all that water is also pulling on the moon and with[color=red] each[/color] rotation it makes the moon move a tiny [color=red]bit[/color] faster .At the same time like the [color=red]brakes[/color] on the wheel of bicycle the [color=red]drag[/color] caused by the Moon's gravity makes the Earth turn just a tiny bit slower .And so after a billion years or so one rotation meaning one day takes [color=red]a lot[/color] longer[color=red] than it once did[/color].
