Kukhazikika kwa Machitidwe a Migodi Migodi yakhala ikuyendetsa chuma m'maiko ambiri, kuphatikizapo Indonesia. Zinthu monga malasha, nickel, mkuwa, golide, bauxite, ndi tin zimagwira ntchito yofunika kwambiri pa mphamvu zapadziko lonse lapansi komanso unyolo wopereka mafakitale. Komabe, ngakhale kuti ntchito zamigodizi zikupereka zinthuzi, zimabweretsanso zotsatirapo zazikulu pa chilengedwe ndi chikhalidwe cha anthu: kusintha kwa malo, mavuto azachilengedwe, komanso kuwonongeka kwa chilengedwe.

Kodi mphamvu ya turbidity mu sedimentology ndi chiyani? Mu sedimentology, imodzi mwa njira zofunika kwambiri pomvetsetsa mapangidwe a sediment m'malo akuya a nyanja ndi mphamvu ya turbidity. Kuyenda kumeneku, komwe nthawi zambiri kumatchedwa "sediment mass flow," kumatsika pansi pa phiri la pansi pa nyanja lomwe limayendetsedwa ndi mphamvu yokoka. Ngakhale kumachitika pansi pa madzi, njirayi imatha... Werengani zambiri

Momwe Mapangidwe a Magnetic Amalembera Mbale Amasinthira Tangoganizirani pansi pa nyanja ngati "chosungira" chachikulu chomwe chimasunga zizindikiro za nthawi. Osati m'mawonekedwe olembedwa, koma m'mapangidwe a maginito omwe ali m'miyala. Mapangidwe awa—mizere ya maginito yofanana pansi pa nyanja—akhala ena mwa umboni wamphamvu kwambiri wakuti ma tectonic plates amasunthadi. Kudzera m'zolemba zamaginito izi, asayansi amatha… Werengani zambiri

Njira Zogwiritsira Ntchito Maginito Pofufuza za Geological: Njira yogwiritsira ntchito maginito ndi imodzi mwa njira zogwiritsidwa ntchito kwambiri pofufuza za geological, pojambula mapu a pansi pa nthaka, kufufuza zinthu zamchere, komanso maphunziro a tectonic. Mfundo yake yaikulu imagwiritsa ntchito kusiyana kwa mphamvu ya maginito ya Dziko Lapansi, komwe kumakhudzidwa ndi kupezeka kwa miyala ya maginito pansi pa nthaka. Chifukwa chakuti miyeso yake ndi yofulumira, ndalama zogwirira ntchito ndizochepa... Werengani zambiri

Momwe Ma Seismograph Amagwirira Ntchito Pozindikira Chivomerezi Zivomerezi ndi chimodzi mwa zinthu zachilengedwe zovuta kwambiri ndipo zimaika miyoyo ya anthu pachiwopsezo chachikulu. Kugwedezeka komwe kumachitika chifukwa cha kusuntha kwa ma tectonic plates, zochitika za volcano, kugwa kwa pansi pa nthaka, komanso kuphulika kopangidwa ndi anthu kumatha kuyenda mtunda wautali kudutsa mu nthaka ya Dziko lapansi ndikukhudza pamwamba. Kuti mumvetse nthawi ndi komwe zivomerezi zimachitika… Werengani zambiri

Ubwino wa Miyala Yamtengo Wapatali mu Kafukufuku wa Zachilengedwe Miyala yamtengo Wapatali nthawi zambiri imaonedwa ngati zinthu zokongola komanso zamtengo wapatali zomwe zimagwiritsidwa ntchito popanga zodzikongoletsera. Komabe, kupitirira kukongola ndi kukongola kwawo, miyala yamtengo Wapatali imakhala ndi chidziwitso chofunikira cha sayansi. Mu kafukufuku wa zamoyo, miyala yamtengo Wapatali imatha kukhala "zosungira" zachilengedwe zomwe zimalemba momwe Dziko Lapansi linapangidwira, momwe zinthu zakuthupi ndi mankhwala zimakhalira pansi, ndi...

Kugwiritsa Ntchito Mwala wa Metamorphic mu Mafakitale Mwala wa Metamorphic ndi mtundu wa mwala wopangidwa kuchokera ku kusintha kwa miyala yomwe inalipo kale (igneous, sedimentary, kapena kale metamorphic) chifukwa cha kutentha kwambiri, kupanikizika kwakukulu, ndi ntchito yamadzimadzi a mankhwala mkati mwa nthaka ya Dziko Lapansi. Njirayi imatchedwa metamorphism. Kusintha kumeneku sikuti nthawi zonse kumapangitsa kuti mwala usungunuke, koma ndikokwanira kusintha kapangidwe ka mchere, kapangidwe kake, ndi... Werengani zambiri

Zinthu Zomwe Zimakhudza Kugawa kwa Mineral Kugawa kwa mchere padziko lapansi ndi pansi pa nthaka sikwachisawawa. Maonekedwe a mchere—kaya ngati tinthu tating'onoting'ono tomwe tafalikira, mitsempha, magalasi a miyala, kapena miyala ikuluikulu—amakhudzidwa ndi njira zingapo za geological zomwe zimachitika kwa nthawi yayitali. Kumvetsetsa zinthu zomwe zimakhudza kugawa kwa mchere ndikofunikira, osati pazifukwa zasayansi zokha… Werengani zambiri
