Zachilengedwe zonse zapadziko lathu lapansi, kutengera kutopa, zimagawanika kukhala zosatha komanso zotha. Ngati zonse zikuwonekera bwino ndi choyambirira - umunthu sudzatha kuzigwiritsa ntchito kwathunthu, ndiye kuti zotopetsa ndizovuta kwambiri. Amagawidwanso m'magulu ang'onoang'ono kutengera kukula kwatsopano:
- zosapitsidwanso - nthaka, miyala ndi mchere;
- zongowonjezwdwa - zomera ndi zinyama;
- osapitsidwanso kwathunthu - minda yolimidwa, nkhalango zina ndi matupi am'madzi mdziko muno.
Kugwiritsa ntchito mchere
Zida zamagetsi zimatanthawuza zinthu zachilengedwe zotha komanso zosasinthika. Anthu akhala akugwiritsa ntchito kuyambira kale. Miyala yonse ndi mchere zimayimiriridwa padziko lapansi mosagwirizana komanso mosiyanasiyana. Ngati pali zinthu zina zambiri ndipo simuyenera kuda nkhawa kuti muzigwiritsa ntchito bwanji, ena ndi ofunika chifukwa cha golide wawo. Mwachitsanzo, lero pali vuto lazinthu zamafuta:
- malo osungira mafuta amatha zaka 50;
- malo osungira gasi atha pafupifupi zaka 55;
- malasha azikhala zaka 150-200, malinga ndi kuneneratu kosiyanasiyana.
Kutengera kuchuluka kwa nkhokwe zazinthu zina, zili ndi malingaliro osiyanasiyana. Kuphatikiza pa mafuta, miyala yamtengo wapatali kwambiri ndi miyala yamtengo wapatali (californium, rhodium, platinamu, golide, osmium, iridium) ndi miyala (eremeevite, buluu garnet, opal wakuda, demantoid, red diamond, taaffeite, poudretteite, musgravite, benitoite, safiro, emarodi, alexandrite, ruby, jadeite).
Zida zanthaka
Malo ofunikira padziko lapansi amalimidwa, kulimidwa, kugwiritsidwa ntchito kulima mbewu ndi malo odyetserako ziweto. Komanso, gawo lina limagwiritsidwa ntchito pokhalamo, malo ogulitsa mafakitale ndi chitukuko cham'munda. Zonsezi zimawonjezera mkhalidwe wa nthaka, zimachedwetsa njira yobwezeretsa nthaka, ndipo nthawi zina zimabweretsa kuwonongeka kwake, kuipitsa nthaka ndi chipululu. Zivomezi zopangidwa ndi anthu ndi chimodzi mwazotsatira za izi.
Flora ndi zinyama
Zomera, monga nyama, ndizinthu zina zowonjezeredwa padziko lapansi, koma chifukwa chakugwiritsa ntchito kwake, vuto la kutha kwathunthu kwamitundu yambiri lingabuke. Pafupifupi mitundu itatu yazinthu zamoyo imazimiririka padziko lapansi ola lililonse. Kusintha kwa zomera ndi zinyama kumabweretsa zotsatira zosasinthika. Uku sikungowononga zachilengedwe zokha, monga kuwononga nkhalango, koma kusintha kwa chilengedwe chonse.
Chifukwa chake, zinthu zachilengedwe zomwe zatha padziko lapansi ndizofunika kwambiri chifukwa zimapereka moyo kwa anthu, koma kuchuluka kwa kuchira kwawo ndikotsika kwambiri kotero kuti sikukuwerengeka zaka, koma zaka zikwizikwi ngakhale mamiliyoni azaka. Sikuti anthu onse amadziwa izi, koma ndikofunikira kupulumutsa maubwino achilengedwe masiku ano, chifukwa kuwonongeka kwina sikungakonzedwenso.
