▁of ▁the ▁magnetic ▁field . ▁The ▁interaction ▁of ▁the ▁magnetic ▁field ▁and ▁solar ▁radiation ▁has ▁an ▁impact ▁on ▁how ▁much ▁radiation ▁reaches ▁the ▁surface ▁of ▁Earth ▁and ▁the ▁integrity ▁of ▁the ▁atmosphere . ▁It ▁has ▁been ▁found ▁that ▁the ▁magnetic ▁pol es ▁of ▁the ▁Earth ▁have ▁revers ed ▁several ▁times , ▁allowing ▁research ers ▁to ▁get ▁an ▁idea ▁of ▁the ▁surface ▁conditions ▁of ▁the ▁planet ▁at ▁that ▁time . ▁The ▁cause ▁of ▁the ▁magnetic ▁pol es ▁being ▁revers ed ▁is ▁unknown , ▁and ▁the ▁intervals ▁of ▁change ▁vary ▁and ▁do ▁not ▁show ▁a ▁consistent ▁interval . ▁It ▁is ▁believed ▁that ▁the ▁revers al ▁is ▁correl ated ▁to ▁the ▁Earth ' s ▁mant le , ▁although ▁exactly ▁how ▁is ▁still ▁deb ated . ▁ ▁Dist ort ions ▁to ▁the ▁Earth ' s ▁magnetic ▁field ▁cause ▁the ▁phenomen on ▁Aur ora ▁B ore alis , ▁commonly ▁called ▁the ▁Northern ▁L ights . ▁The ▁magnetic ▁field ▁stores ▁energy ▁given ▁by ▁cos mic ▁particles ▁known ▁as ▁solar ▁wind , ▁which ▁causes ▁the ▁magnetic ▁field ▁lines ▁to ▁expand . ▁When ▁the ▁lines ▁contract , ▁they ▁release ▁this ▁energy , ▁which ▁can ▁be ▁seen ▁as ▁the ▁Northern ▁L ights . ▁ ▁At mos pher ic ▁influ ences ▁ ▁The ▁Earth ' s ▁climate ▁changes ▁over ▁time ▁due ▁to ▁the ▁planet ' s ▁atmos pher ic ▁composition , ▁the ▁sun ' s ▁lum inos ity , ▁and ▁the ▁occurrence ▁of ▁cat ast roph ic ▁events . ▁ ▁At mos pher ic ▁composition ▁affect s ▁and ▁is ▁affected ▁by ▁the ▁bi
