Mehloli ea metsi ea Lefatše e na le metsi a ka tlase ho lefatše le metsi a holim'a lefatše. Ha li sebelisoe ke batho le liphoofolo feela, empa li ea hlokahala bakeng sa lits'ebetso tse fapaneng tsa tlholeho. Metsi (H2O) a metsi, a tiile, kapa a na le moea o mongata. Kakaretso ea mehloli eohle ea metsi e etsa hydrosphere, ke hore, khetla ea metsi, e etsang 79.8% ea lefatše. E na le:

  • maoatle;
  • maoatle;
  • linoka;
  • matša;
  • mekhoabo;
  • matamo a maiketsetso;
  • metsi a ka tlas'a lefatše;
  • mouoane oa sepakapaka;

  • sekoahelo sa lehloa;
  • leqhoa.

Bakeng sa ho boloka bophelo, batho ba tlameha ho noa metsi letsatsi le leng le le leng. Ke metsi a hloekileng feela a loketseng sena, empa polaneteng ea rona a ka tlase ho 3%, empa joale ke 0.3% feela e fumanehang. Mehloli e meholohali ea metsi a nooang e Russia, Brazil le Canada.

Ts'ebeliso ea lisebelisoa tsa metsi

Metsi a ile a hlaha Lefatšeng lilemong tse ka bang limilione tse likete tse 3,5 tse fetileng, 'me a ke ke a hlokomeloa ke sesebelisoa se seng. The hydrosphere ke ea leruo le sa feleng la lefats'e, ntle le moo, bo-ramahlale ba qapile mokhoa oa ho etsa metsi a letsoai a macha e le hore a ka sebelisoa bakeng sa ho nooa.

Mehloli ea metsi e hlokahala eseng feela ho ts'ehetsa bophelo ba batho, limela le liphoofolo, empa hape e fana ka oksijene nakong ea ts'ebetso ea photosynthesis. Hape, metsi a bapala karolo ea bohlokoa ho theheng hoa maemo a leholimo. Batho ba sebelisa sesebelisoa sena sa bohlokoahali bophelong ba letsatsi le letsatsi, temong le indastering. Litsebi li hakanya hore litoropong tse kholo motho o sebelisa lilithara tse ka bang 360 tsa metsi ka letsatsi, mme hona ho kenyelletsa tšebeliso ea phepelo ea metsi, likhoerekhoere, ho pheha le ho noa, ho hloekisa ntlo, ho hlatsoa, ​​ho nosetsa limela, ho hlatsoa likoloi, ho tima mollo, jj.

Bothata ba tšilafalo ea Hydrosphere

E 'ngoe ea mathata a lefats'e ke tšilafalo ea metsi. Mehloli ea tšilafalo ea metsi

  • metsi a litšila malapeng le liindastering;

  • litšila tse tiileng tsa masepala.

Ka tlhaho ho na le ketsahalo e kang ho itlhoekisa ha 'mele ea metsi, empa lebaka la anthropogenic le susumetsa biosphere hoo ha nako e ntse e feta, linoka, matša, maoatle li ntseng li ntlafatsoa le ho feta. Metsi a silafala, a fetoha a sa tšoaneleheng feela bakeng sa ho nooa le ts'ebeliso ea lapeng, empa le bakeng sa bophelo ba mefuta ea leoatleng, ea linoka, ea limela le liphoofolo. Ho ntlafatsa maemo a tikoloho, haholo-holo hydrosphere, ho hlokahala hore re sebelise mehloli ea metsi ka mokhoa o utloahalang, re e boloke le ho etsa mehato ea ts'ireletso ea 'mele ea metsi.
