D\u00fcnya, 23 derecelik bir e\u011fimle durur. Bu e\u011fim de mevsimlere sebeptir. E\u011fer bu e\u011fim olmasayd\u0131, kutuplar s\u00fcrekli alacakaranl\u0131kta olur, okyanustan kalkan su buharlan kuzeye ve g\u00fcneye do\u011fru hareket eder, \u00fcst \u00fcste buz k\u0131talar\u0131 meydana getirerek, ekvatorla buzlar aras\u0131nda bir \u00e7\u00f6l b\u0131rak\u0131rd\u0131. Buzul nehirleri kanyonlar i\u00e7inden g\u00fcrleyerek ve etraflar\u0131n\u0131 a\u015f\u0131nd\u0131rarak okyanuslar\u0131n tuzla kapl\u0131 yataklar\u0131na akar ve ge\u00e7ici tuzlu su havuzlar\u0131 meydana getirirlerdi. \u0130nan\u0131lmaz b\u00fcy\u00fckl\u00fckteki buz k\u00fctlelerinin a\u011f\u0131rl\u0131\u011f\u0131 kutuplar\u0131 bask\u0131 alt\u0131na al\u0131r ve ekvatorumuzun \u015fi\u015fip patlamas\u0131na, en az\u0131ndan yeni bir bel ku\u015fa\u011f\u0131 ihtiyac\u0131 g\u00f6stermesine sebep olurdu. Okyanuslarda su seviyesinin d\u00fc\u015fmesi, ortaya yeni ve \u00e7ok geni\u015f karalar\u0131n \u00e7\u0131kmas\u0131na ve d\u00fcnyan\u0131n her taraf\u0131nda ya\u011fmurlar\u0131n azalmas\u0131na yol a\u00e7ar, bunlar da korkun\u00e7 neticeler do\u011fururdu.<\/p>\n

Ay, d\u00fcnyadan 240.000 mil (yakla\u015f\u0131k 400.000 km.) uzakl\u0131ktad\u0131r ve g\u00fcnde iki defa mey ana ge en med cezirler, onun varl\u0131\u011f\u0131n\u0131 bize nazik\u00e7e hat\u0131rlat\u0131r.

Yer, \u015fiddetli hareketlerle \u00e7atlar ve havadaki ak\u0131mlar her g\u00fcn tayfunlara yol a\u00e7ard\u0131.<\/p>\n
