Isingeniso: Ingabe Abantu Bangaba Izinsalela Zezinkomba?
Umqondo wokuthi abantu babe yizinsalela zenkomba esikhathini esizayo ungase ubonakale njengenganekwane yesayensi, kodwa njengoba ucwaningo lwesayensi yezindawo luthuthuka, kufanelekile ukuhlola ukuthi kungenzeka yini. Izinsalela zenkomba zingamathuluzi abalulekile kusayensi yokwakheka komhlaba asiza ososayensi ukuba baqonde umlando woMhlaba. Ziyizinsalela zezinto eziphilayo ezaphila phakathi nenkathi ethile yesikhathi futhi zisetshenziselwa ukukhumbula ukwakheka kwamadwala. Nokho, ukusetshenziswa kwezinsalela zenkomba zendabuko kunemingcele, okuholela abanye ososayensi ukuba bacabangele izindlela ezintsha zokusebenzisa izinsalela zenkomba.
Kulesi sihloko, sizohlola umqondo wabantu njengezinsalela zenkomba ezingase zibe khona. Sizoxoxa ngokuthi iyini imivubukulo yenkomba, ukubaluleka kwayo esikhathini sokuma komhlaba, ukulinganiselwa kwezinsalela zenkomba yendabuko, ukuthi abantu bangaba kanjani izinsalela zenkomba, indlela yokusebenzisa abantu njengezinsalela zenkomba, izinselele kanye nezimiso zokuziphatha zokusebenzisa abantu njengezinsalela zenkomba, kanye ikusasa lezinsalela zenkomba.
Ukuqonda Izinsalela Zenkomba Nokubaluleka Kwazo
Izinsalela zenkomba ziyizinsalela zezinto eziphilayo ezaziphila ngesikhathi esithile futhi zinezici ezihlukile ezenza zibonakale kalula. Zisetshenziswa njengethuluzi lokudala ukwakheka kwamadwala kanye nokuhlobanisa izendlalelo zamadwala ezivela ezindaweni ezahlukene. Isibonelo, uma uhlobo oluthile lwe-trilobite lutholakala ongqimbeni lwamadwala, kuyaziwa ukuthi ungqimba lwamadwala lusuka enkathini ethile yesikhathi. Ukusetshenziswa kwezinsalela zenkomba kuvumela izazi zokwakheka komhlaba ukuthi zenze umugqa wesikhathi womlando womhlaba.
Izinsalela zenkomba zibalulekile ngoba zinikeza indlela yokwakheka kwamadwala okungenzeka aziqukethe ezinye izinhlobo zezinsalela. Ziphinde zivumele izazi ze-geologists ukuthi zihlobanise izingqimba zamadwala ezivela ezindaweni ezahlukene, okubalulekile ekuqondeni umlando woMhlaba. Izinsalela zenkomba zinganikeza ulwazi ngendawo ezihlala kuyo, njengesimo sezulu, indawo, kanye nemvelo yangaleso sikhathi. Ziwusizo futhi ekuqondeni ukuvela kwezinto eziphilayo ngokuhamba kwesikhathi.
