Hydrosphere ke mehloli eohle ea metsi e polaneteng, e arotsoeng Leoatleng la Lefatše, metsi a ka tlase ho lefatše le metsi a kontinenteng. E na le mehloli e latelang:
- Linōka le matša;
- Metsi a ka tlas'a lefatše;
- leqhoa;
- mouoane oa sepakapaka;
- maoatle le maoatle.
Metsi a hlaha ka mefuta e meraro ea 'mele,' me phetoho ho tloha mokelikeli ho ea ho e tiileng kapa e nang le khase, ka lehlakoreng le leng, e bitsoa potoloho ea metsi ka tlhaho. Potoloho ena e ama maemo a leholimo le maemo a leholimo.
Bothata ba tšilafalo ea metsi
Metsi ke mohloli oa bophelo bakeng sa bophelo bohle ba lefats'e, ho kenyeletsoa batho, liphoofolo, limela, hape le nka karolo lits'ebetsong tse fapaneng tsa 'mele, lik'hemik'hale le tsa bioloji. Ka lebaka la hore batho ba sebelisa metsi hoo e ka bang mafapheng ohle a bophelo, boemo ba lisebelisoa tsena tsa tlhaho bo mpefetse haholo hajoale.
E 'ngoe ea mathata a bohlokoahali ho hydrosphere ke tšilafalo. Bo-rasaense ba supa mefuta e latelang ea tšilafalo ea enfelopo ea metsi:
- manyolo;
- lik'hemik'hale;
- metjhini kapa mmele;
- ea tlhaho;
- mogote;
- mahlaseli a kotsi;
- ka ntle feela.
Ho thata ho bolela hore na ke mofuta ofe oa tšilafalo o kotsi ho feta tsohle, tsohle li kotsi ka mekhahlelo e fapaneng, leha, ho ea ka rona, tšenyo e kholo e bakoa ke ts'ilafalo ea radioactive le ea lik'hemik'hale. Mehloli e meholohali ea ts'ilafalo e nkuoa e le lihlahisoa tsa oli le litšila tse tiileng, metsi a litšila a malapeng le a indastering. Hape, metsoako ea lik'hemik'hale e tsoang moeeng e kenella ka metsing hammoho le pula.
Bothata ba metsi a nooang
Ho na le mehloli e meholo ea metsi polaneteng ea rona, empa ha se eona kaofela e loketseng hore batho ba e je. Ke 2% feela ea mehloli ea metsi ea lefats'e e tsoang metsing a hloekileng a ka nooang, kaha 98% ke metsi a letsoai haholo. Hajoale, linoka, matša le mehloli e meng ea metsi a nooang li silafetse haholo, mme le kalafo ea mekhahlelo e mengata, e sa etsoang kamehla, ha e thuse boemo bona haholo. Ntle le moo, mehloli ea metsi e arotsoe ka ho lekana polaneteng, mme lits'ebetso tsa likanale tsa metsi ha li ntlafatsoe hohle, ka hona ho na le libaka tse ommeng tsa lefats'e moo metsi a turang ho feta khauta. Moo, batho ba bolaoa ke ho felloa ke metsi 'meleng, haholo bana, hobane bothata ba khaello ea metsi a nooang bo nkuoa bo sebetsa ebile bo le lefats'e kajeno. Hape, ts'ebeliso ea metsi a litšila, a sa hloekang hantle, e lebisa mafung a fapaneng, a mang a bile a isa lefung.
Haeba re sa tšoenyehe ka hore na re ka fokotsa boemo ba tšilafalo ea hydrosphere mme re sa qale ho hloekisa 'mele ea batho, batho ba bang ba tla tšeloa chefo ke metsi a litšila, ha ba bang ba ka omella ntle ho eona.
