Iimpawu eziphambili zomhlaba njengequmrhu yasezulwini

Land - yeyona inkulu iiplanethi ezisentlabathini. Yiyo le indawo yesithathu ukusuka Sun umgama kwaye yisathelayithi - iNyanga. Umhlaba kuphela umhlaba ukuba umiwe ngabantu abahlala. impucuko Human yinto ebalulekileyo kunefuthe elingqalileyo ebusweni bomhlaba. Ziziphi ezinye iimpawu eziziimpawu kwilizwe lethu?

I imilo kunye nobunzima, indawo

I Umhlaba umzimba omkhulu yesiqalo, ubunzima bayo ngu 6 iitoni septillionov. Xa uhlobo kufana namazambane okanye eliphakathi. Yiloo nto abaphandi wambi ibizwa ngokuba ifom eye iplanethi yethu, "potatoid" (ukusuka iitapile IsiNgesi -. amazambane). Kwakhona iimpawu ezibalulekileyo uMhlaba umzimba yasezulwini, echaza indawo yayo lomhlaba. iplanethi yethu use ngeekhilomitha 149.600.000 ukusuka elangeni. Thelekisa, Mercury yi amaxesha 2.5 kufutshane isikhanyiso ngaphezu Earth. Kodwa iPluto ngokuphindwe 40 akude eLangeni kwe phephandaba.

Abamelwane iplanethi yethu

Inkcazelo emfutshane ye Umhlaba njengequmrhu yasezulwini kufuneka siqulathe ulwazi kunye satellite yayo - iNyanga. ubunzima bayo ngamaxesha 81,3 ngaphantsi komhlaba. Earth lijikeleza phezu axis yayo, apho lumiswe-engile degrees 66.5 ngokuphathelele kwi-moya Orbital. Esinye seziphumo ezingundoqo ukujikeleza koMhlaba ngeenxa axis yayo eshukumayo yayo Orbital - utshintsho imini nobusuku kunye namaxesha onyaka.

Iplanethi yethu yinxalenye yeqela ebizwa ngokuba yi-langa ezisentlabathini. Olu didi zihlanganisiwe Venus, iMars Mercury. iiplanethi ezinkulu kakhulu ezikude - Jupiter, nguNeptune, likaSaturn, kunye Uranus - phantse yonke yabhalwa ngeegesi (hydrogen kunye helium). Zonke iiplanethi ziphantsi kudidi zomhlaba zisenokusekelwa axis wayo, kwakunye umendo okweqanda ujikeleza ilanga. omnye kuphela iPluto kuphela ngenxa iimpawu zayo ayiqukwanga izazinzulu naliphi iqela elinye.

kuqweqwe

Enye iimpawu eziphambili zomhlaba njengequmrhu yasezulwini kuba phambi kwesikhoko leyo, ngathi isikhumba esibhityileyo, lugubungela komhlaba planethi. Le ibandakanya isanti, udongwe kunye neeminerali ezahlukeneyo, namatye. Ebubanzini avareji qweqwe lomhlaba km-30, kodwa kwezinye iindawo, ixabiso layo ngu 40-70 km. Oosomajukujuku bathi kolu qweqwe lomhlaba - hayi zeendondo ichulumancisayo kwendawo yonke. Kwezinye iindawo vzdyblena nasentshonalanga, phakathi kwabanye, phezu koko, uwela phantsi kwamakhwapha elikhulu.

ezilwandle

Ngoncedo uphawu yomzimba Umhlaba yasezulwini kufuneka siquke kukhankanywa kwezilwandle. Zonke emigodini azele ngamanzi Emhlabeni, nto leyo enika yokuhlala namakhulukhulu kweentlobo ubomi. Noko ke, izityalo ezininzi kunye nezilwanyana zifumaneka kumhlaba. Ukuba ufake zonke izidalwa eziphilayo ezihlala emanzini, phezu isikali mnye, kunye nabo bahlala kulo mhlaba - kwelinye icala, bekuya kuba nzima ukuba okha kunye nabemi sushi. ubunzima bayo baya kuba ngo-2000 kwakhona. Kuyamangalisa kakhulu, kuba loo ndawo Ocean na ngaphezu kwezigidi 361 square metres. ukusuka okanye 71% ye ngaphantsi komhlaba. Iilwandle isici esasenza iplanethi yethu, ndawonye phambi oksijini emoyeni. Ngaphezu koko, ukuba umyinge wamanzi amatsha emhlabeni yi-2.5% kuphela, ubunzima lokuphumla uba etyuwa omalunga 35 PPM.

Core neyokwaleka

kuba achaza Umhlaba njengoko umzimba yasezulwini akaphelelanga ngaphandle kwenkcazelo kwesakhiwo yayo yangaphakathi. core zomhlaba ngumxube eshushu zesinyithi ezimbini - nickel, nesinyithi. It singqongwe ngokomthamo ashushu incangathi, nto leyo efana nodongwe. It silicates - izinto ezifanayo kumafa ukuya esantini. lobushushu yabo degrees amawaka aliqela. Le mass viscous kuthiwa yokwaleka. kwithempritsha yayo akufani yonke. Kufuphi qweqwe lomhlaba of 1000 degrees kwaye osondela olungundoqo inyuswe ukuya degrees 5000. Noko ke, nkqu kwiindawo ezikufutshane kolu qweqwe lomhlaba, nengubo enkulu yabanda okanye ashushu. Le ndawo ishushu zibizwa ngokuba amagumbi daka. Daka elivutha ngokusebenzisa umphezulu kolu qweqwe lomhlaba, kwaye ezi iindawo kwakheka mlilo, iintlambo mlilo, imigqomo yamanzi.

Umoya ojikeleze umhlaba

Enye inkalo yoMhlaba njengequmrhu yasezulwini kuba phambi emoyeni. ubukhulu bayo-100 kuphela km. Air - umxube igesi. It iqulathe amacandelo amane - nitrogen, argon, ioksijini kunye carbon dioxide. Ezinye izinto ezikhoyo emoyeni hi mpimo lowutsongo. Uninzi zezulu ime emoyeni umaleko, nto leyo ikufutshane ngaphantsi komhlaba. Le ndawo kuthiwa eziFihliweyo. ubukhulu bayo-10 km, kwaye ubunzima ifikelela 5000 ezigidi iitoni.

Nangona kumaxesha amandulo abantu abazange eliqinisekileyo uMhlaba njengequmrhu yasezulwini, nokuba ke bekucingelwa ukuba libhekisela ngqo udidi iiplanethi. Njani ookhokho bethu ukuba enze loo nto? Isibakala sokuba basebenzisa isibhakabhaka ebusuku endaweni iwotshi kunye neekhalenda. Nalapho ke kwacaca ukuba izibane ezahlukeneyo esibhakabhakeni lihamba ngendlela yabo. Enye phantse alubathundezi (ukuba ekuthiwa iinkwenkwezi), kunye nabanye etshintsha rhoqo nendawo yazo iinkwenkwezi. Kungenxa yoko le imizimba yasezulwini wabizwa ngokuba iiplanethi (lithatyathwa kwigama lesiGrike elithi "iplanethi" lithetha "bebhadula").
