Lo mmandla ahlala kwilizwe Umhlaba emhlabeni, yaye razoobrazie yayo emikhulu

planet Blue ebizwa ngokuba uninzi umphezulu kuthatha i medium zolwelo: iilwandle, iilwandle, imilambo kunye namachibi. Ngokubanzi, ilizwe uMhlaba ithatha nje kuphela esithathwini enye kumphezulu wayo. Kodwa kwangaxeshanye uyakwazi ukuva igama "Green Planet", ngokuba kuphela apha (njengokuba sisazi ngeli nqanaba lokuhlola space) yimeko lobomi sisazi, kwaye iintlobo ezahlukileyo zemithi, amatyholo kunye zengca efafazwe emhlabeni shades aluhlaza .

Yintoni iimpawu wenza isiqabu komhlaba

Amashumi amathathu ekhulwini abenza wathabatha ilizwe umhlaba, babe neempawu zabo, njengoko ezichaphazela le indawo, kwakunye enxulumene ukuhamba ziitectonic plates. Highlands, apho kufumaneka kweli nqanaba Earth emhlabeni, wasekwa amakhulu ezininzi, amawaka okanye kwizigidi zeminyaka eyadlulayo xa ziitectonic plates zingqubane, yaye ngoku i-ngaphezu kwesinye kwisithathu ilizwe.

Iintlango, ukuba ummandla eqhelekileyo epholileyo kwaye ezahlukeneyo umoya eziphakamileyo, beshumayela Zinjengeqhezu amabini ekhulwini.

Kwakhona, ilizwe iplanethi zigqunywe ngamahlathi, nemihlaba yeenkuni kunye amathafa, leyo ibekwe kulo mmandla weentaba. Bebonke kukho malunga-50 pesenti yomhlaba, apho kwimimandla eluhlaza, umzekelo, amaplanga yimvula. Small (noko) kwaye kufuneka umhlaba umkhenkce: 10% - Antarctica, inxalenye kumantla Eurasia nakuMntla Melika.

division ezweni amazwekazi

Ngoku ilizwe umhlaba yahlulwe kumazwekazi ezinkulu ezintandathu. I inkulu kubo - oku Eurasia, ilandelwe yi-Afrika (30 ezigidi macala Km.), Intshona Melika (izigidi ezingama-20 ubude macala onke Km.), Umzantsi Melika (18 million macala Km.), Antarctica (14 (million 55 ezikwere zeekhilomitha.) million macala onke. km), kunye Australia (8.5 million macala onke. km). Onke manani zinikwe ngohlobo ajikelezayo kwaye zisekelwe phezu kwiindawo ezingqonge ziqithi. amazwekazi Map sikuvumela ukuba ubone uqonde apho ibekwe khona lizwekazi.

Okubangel 'umdla kukuba kukho ingcamango malunga sverhmaterike enye. Ngokutsho kwakhe, amazwekazi zikhoyo ngoku zagqityelwa ngaphambili omnye.

Le lizwekazi ngokuba Pangea, wahlamba ulwandle wakhe omkhulu, izazinzulu ogama Panthalassa. Ubungqina yale mbono kukuba kungqameko amazwekazi zinokudityaniswa, yaye phantse akukho zimpazamo iya kuba njalo, kwaye nangoku iintshukumo amazwekazi kunye iziqithi. Oku ayinamsebenzi ehlabathini lonke: ishumi kuphela ezinye iisentimitha ngonyaka, kodwa kukho into enjalo.

Ulwazi oluninzi malunga enkulu amazwekazi, iziqithi , wahlamba neelwandle zabo

Eurasia - izwekazi Kulowo uhlanjiweyo zonke iilwandle zehlabathi. Xa kuthathelwa ingqalelo indawo yayo ikwindawo yesithathu ngobukhulu kwisiqithi Kalimantan. Ngenxa emdeni wayo enkulu phezu nemisinga kunokubonwa nayiphi na imozulu kunye neemeko zokusingqongileyo, ezinako komiswa planethi - ukusuka zasebusika ngqwabalala ukuba kumshiya. Kuyaphawuleka ukuba ilizwekazi yahlulwe ezimbini zehlabathi - Europe kunye Asia. IYurophu ngezantsi onke amanzi olwandle phakathi kwezinye iinxalenye zehlabathi - m 300 (nge-avareji). E Asia, elileli: emazantsi-ntshona inxalenye yayo, oko usingasiqithi inkulu ehlabathini - umArabhi, ukuya kummandla Eurasia zezethu leziqithi likhulu - Greater Sunda Islands.

Afrika - ilizwekazi kunye nommelwane Madagascar, esi siqithi yesine ukuba likhulu ehlabathini. Zonke eyaziwa ngokuba entlango sikhulu ehlabathini, ebizwa weSahara. Ihlanjwe kwilizwekazi iilwandlekazi ezimbini - i-Atlantic namaNdiya. Xa emazantsi zwekazi uLwandle lweMeditera, leyo eyahlula iYurophu kunye Afrika. Kuyaphawuleka ukuba Afrika, njengokuba yinxalenye yehlabathi, yindawo apho ngaphezulu kwe-70% abemi kuhlala kubuhlwempu.

I single inxalenye umqadi, ezibandakanya amazwekazi ezimbini

North and Umzantsi Melika - kumazwekazi ezimbini, zizonke ezakha enye inxalenye yehlabathi - America. Bona ebekwe ngokupheleleyo saseNtla Koloni kwaye idityaniswe sezwe Panama. Kuba Intshona Melika ziquka siqithi sikhulu ehlabathini - eGreenland, kwakunye nenkalo sesihlanu - Baffin Island. Kokuhlanjwa iilwandlekazi amathathu - i-Atlantic, Arctic Pacific. Umzantsi Melika - i-Atlantic kunye neelwandle Pacific.

Le, kodwa amazwekazi incinane akukho ezibalaseleyo ngaphantsi

Antarctica - eliphezulu (2400 iimitha ngaphezu komphakamo wolwandle kwi-avareji) kunye (umyinge yokusebenza ubushushu - ^-70 ° C) obubanda lizwekazi on Earth, ebekwe ngokupheleleyo kwi -Southern saseNtla. On nommandla wayo, ukongeza umkhenkce ongunaphakade, lo ngowona South Pole, leyo phantse ngexesha elinye kunye embindini kweli lizwekazi. Ihlanjwe ilizwe Pacific, iilwandle Indiya kunye Atlantic.

Australia - kwilizwekazi incinane, sime ikhweyitha emazantsi, phantse phakathi igqitha Tropic of Capricorn. Kule nkalo, oko kwilizwekazi lawona apho kukho kusekho kancinci amahlathi ashinyeneyo kunye iincopho ezigqunywe likhephu ndawo. Australia ithatha ilizwe lonke, leyo ibizwa ngegama yelizwekazi, ayinazo analogu kwihlabathi lethu. yesibini-rated ubungakanani iziqithi Intsimi ezweni osecaleni ehlabathini - New Guinea.
