Indlela Amakristalu Akhiwa Ngayo
Kwangathi
Njengoba uMhlaba wakha, kwadalwa amakristalu, futhi ayaqhubeka akha njengoba iplanethi ishintsha.
Amakristalu aziwa ngokuthi i-DNA Yomhlaba, ipulani yokuziphendukela kwemvelo. Lezi zimbiwa zingabagcini bamarekhodi boMhlaba, futhi zisabalele emhlabeni wonke. Ngokutadisha amakristalu, kuvumela us ukufunda ukuthuthukiswa kweplanethi yethu phakathi nezigidi zeminyaka. Lawa amaminerali akhula ngaphansi kwengcindezi enkulu, amanye amila emigedeni engaphansi komhlaba, amanye akhula abe yizingqimba, kanti amanye aphuma kulo mhlaba (isb. ama-Meteorites).
Izakhiwo zekristalu ziyathinteka ngendlela eyakhiwe ngayo. Noma ngabe bangaluphi uhlobo, olwabo isakhiwo sekristalu ingamunca, yonge, igxile futhi ikhiqize amandla, ikakhulukazi ku-electromagnetic waveband. Uhlobo ngalunye lwamakristalu lunesakhiwo salo sangaphakathi esakhiwe uxhaxha lwamaminerali futhi yilokho okuchaza ikristalu. I-lattice ye-athomu ehlelekile futhi ephindaphindayo ihlukile ezinhlotsheni zayo. Kungakhathaliseki ubukhulu bekristalu, izoba nesakhiwo sangaphakathi esifanayo ncamashi esingabonakala kalula ngesibonakhulu. Ngenkathi i-crystal lattice yindlela amakristalu abonakala ngayo, amakristalu afana asebenza ngebhethri inemibala eminingana eyahlukene eyenza abantu bakholwe ukuthi bahlukene. ngamanye amazwi, kungakhathaliseki umbala, kuyilapho izakhiwo zangaphakathi zifana, zihlukaniswa njengekristalu efanayo. Kubalulekile ukubona ukwakheka kwangaphakathi ukuhlukanisa ikristalu kunamaminerali akhiwa ngawo. Ezimweni eziningi, okuqukethwe kwamaminerali kuyehluka kancane okudala amakristalu emibala ehlukene. Nakuba amakristalu amaningi angakhiwa avela kumaminerali afanayo, uhlobo ngalunye luzokhanya ngokuhlukile. Emgogodleni wekristalu yi-athomu nezingxenye zayo. Ihlanganisa izinhlayiya ezijikelezayo phakathi nendawo, i-athomu inamandla. Ikristalu ingase ibukeke inganyakazi; kodwa empeleni liyandindizela futhi likhipha imvamisa ethile ezingeni lamangqamuzana. Yilokhu okunikeza ikristalu amandla ayo.
Ezinsukwini zokuqala, uMhlaba waqala njengefu legesi elakha isitsha sothuli esiminyene. Lokhu kwangena ebholeni elincibilikisiwe elishisayo, elaziwa ngokuthi umnyombo woMhlaba. Eminyakeni eyizigidi, ungqimba oluncane lwento encibilikisiwe ebizwa ngokuthi i-magma, luphole lube uqweqwe okuyingubo yoMhlaba. Lolu qweqwe lucishe lube ngamamayela angu-3 ubukhulu. Ngaphansi koqweqwe, i-magma encibilikisiwe ecebile eshisayo namaminerali iyaqhubeka nokubilisa futhi amakristalu amasha ayaqhubeka nokwakheka.
