Iyini iMetamorphic Rock? I-Metamorphic rock ingenye yezinhlobo ezintathu eziyinhloko zamadwala ezakha ungqimba loMhlaba, kanye namadwala angenawo umoya kanye nalawo angenawo umoya. Igama elithi "metamorphic" livela egameni lesiGreki elisho "ushintsho esimweni." Lichaza inqubo yokwakheka kwamadwala angenawo umoya okwenzeka ngaphansi kwezimo zokucindezela okuphezulu, izinga lokushisa eliphezulu, noma kokubili, okuguqula idwala... Funda kabanzi
Ukubaluleka Kwezifundo Ze-Paleontological Kwe-Geology Ucwaningo lwe-paleontology ludlala indima ebalulekile ekuqondeni umlando woMhlaba kanye nokuvela kokuphila. I-Paleontology, okusho ukuthi "ucwaningo lwempilo yasendulo," igatsha lesayensi eligxile ekufundweni kwezinsalela—izinsalela noma iminonjana yezinto eziphilayo ezaphila esikhathini esidlule. Njengengxenye ebalulekile ye-geology, i-paleontology inikeza ukuqonda okubalulekile… Funda kabanzi
Indlela Okwenzeka Ngayo Ukungcoliswa Kwamanzi Angaphansi Komhlaba Ukungcoliswa kwamanzi angaphansi komhlaba kuyinkinga ekhathazayo emvelweni ezingxenyeni ezahlukene zomhlaba, okuhlanganisa ne-Indonesia. Amanzi angaphansi komhlaba avame ukubhekwa njengomthombo ophephile wamanzi ahlanzekile ngoba atholakala ngaphansi kobuso, evikelwe ekungcoleni komhlaba. Kodwa-ke, empeleni, amanzi angaphansi komhlaba awakhululekile ngokuphelele… Funda kabanzi
Indima Yesayensi Yokwakheka Kwezinto Eziphilayo Ekusimeni Kwemvelo Isayensi Yokwakheka Kwezinto eziphilayo iwukufunda ngoMhlaba, okuhlanganisa izinto eziwubumbayo, isakhiwo, izinqubo ezenzeke ngokuhamba kwesikhathi, kanye nomlando wokuphila ophilayo njengoba ulotshwe emadwaleni. Emashumini eminyaka amuva nje, kuye kwanakwa kakhulu indima yesayensi yokwakheka kwezinto eziphilayo ekusimeni kwezemvelo. Ngale nje kokuqonda umlando nesakhiwo soMhlaba, isayensi yokwakheka kwezinto eziphilayo… Funda kabanzi
Ubudlelwano Phakathi Kokucindezela Nokushisa Ekwakhekeni Kwamadwala Amadwala ebusweni bomhlaba angumphumela wezinqubo eziyinkimbinkimbi nezihlukahlukene ze-geological. Lezi zinqubo zokwakheka kwamadwala zithonywa kakhulu yizici ezimbili eziyinhloko: ukucindezela nokushisa. Kulesi sihloko, sizohlola ubudlelwano phakathi kokucindezela nokushisa ekwakhekeni kwamadwala, kanye nokuthi lezi zici ezimbili... Funda kabanzi
Ubudlelwano Phakathi Kwe-Geology Ne-Archaeology Isingeniso Izinkambu ezimbili zesayensi, i-geology kanye ne-archaeology, nakuba zihluke kakhulu, zihlobene kakhulu ekuqondeni umlando woMhlaba kanye nentuthuko yabantu. I-Geology, njengocwaningo lwesayensi loMhlaba, okuhlanganisa izinto eziwubumbayo kanye nezinqubo eziwushintshayo ngokuhamba kwesikhathi, inikeza isikhathi esibanzi sokuqonda izinguquko ezenzeka...

Kuyini i-Metamorphism kanye nezibonelo? I-Metamorphism inqubo ye-geological eshintsha i-mineralogy, ukuthungwa, kanye nesakhiwo samatshe ngenxa yezinguquko ezimweni zemvelo, njengokushisa, ingcindezi, kanye nomsebenzi wamakhemikhali. Le nqubo yenzeka ekujuleni kongqimba loMhlaba, lapho amatshe akhona evezwa khona ezimweni ezihluke kakhulu kulezo akhiwe kuzo. Lesi sihloko sizochaza… Funda kabanzi
Amasu Akamuva Okumapha Kwezwe Imephu yezwe iyisici esiyisisekelo sesayensi yomhlaba, edlala indima ebalulekile ezinhlobonhlobo zezicelo, kusukela kwisayensi eyisisekelo kuya ekuhlolweni kwemithombo yemvelo kanye nokunciphisa izinhlekelele. Amasu okumapha kwezwe aye athuthuka kakhulu ngokuhamba kwesikhathi, ikakhulukazi ngokufika kobuchwepheshe obuthuthukisiwe kanye nezindlela ezintsha. Isihloko… Funda kabanzi
Ukuzinza Ekuphathweni Kwezinsiza Zamaminerali Ukuzinza kanye nokuphathwa kwezinsiza zamaminerali kuyimibono emibili ethola ukunakwa okwandayo enkathini yanamuhla. Njengoba inani labantu emhlabeni wonke likhula kanye nesidingo sezinto zokusetshenziswa, ukuphathwa kwezinsiza zamaminerali sekuyinto ebalulekile ekusekeleni intuthuko yezomnotho ngenkathi kulondolozwa imvelo. Lesi sihloko sizohlola umqondo wokuzinza… Funda kabanzi
Ayini Ama-Tectonics Epuleti Elihlukene? Isingeniso Umhlaba uyiplanethi eguquguqukayo futhi eshintsha njalo. Omunye wemibono ebaluleke kakhulu ekuqondeni amandla oMhlaba yi-tectonics yamapuleti. Leli gama libhekisela ekuhambeni nasekusebenzisaneni kwamapuleti amakhulu akha ungqimba loMhlaba. Ekufundweni kwama-tectonics amapuleti, izinhlobo eziningana zemingcele yamapuleti ziyaqashelwa, enye yazo... Funda kabanzi
