Malunga namhlanje: yintoni imilo le Umhlaba?

iimbono Astronomical lonke uluntu kuyilwa phezu kangangeenkulungwane. Ukuqalisa eYiputa yamandulo kunye neempucuko mhlawumbi ngaphambili, abaphengululi wathuma ujongo ezulwini, ukuzama ukufunda okungakumbi ngalo isakhiwo ihlabathi lethu. Nomdla, Kakade ke, imilo kunye nobukhulu Umhlaba.

Ukususela ngoko, siye phambili kakhulu. izibakala Kwanele ngoku sinokuthi ngokuqinisekileyo.

Ke enye le mibuzo: yintoni imilo le Umhlaba? Imbali ezahlukeneyo izimvo malunga imilo iplanethi yethu obude kunye umdla kakhulu. Waya umgca amadoda ohlonitshwayo izazinzulu ixesha lethu, kwiZigaba Aphakathi nobudala. Kuba inyaniso (lowo Wabambelela kuzo) ukuba sele ukubatshutshisa wada wafa. Kodwa ke inyaniso abazi akwaliwa.

Ke ngoku yintoni imilo Umhlaba 4 iklasi yesikolo bathi ngokuzithemba ngokupheleleyo.

Masikhumbule njani kwizinto enyanisweni kunye iintlobo iplanethi yethu ekhaya.

Imilo Umhlaba

Kwinkulungwane edluleyo, uluntu likwazile ukwenza uvale enkulu phambili: ukuze uqalise kwisiphekepheke yokuqala ukuya kwisithuba elikude enikiweyo. Abo nayo (wathumela) Scientist photo emhlabeni. Yaba umzimba ezintle yasezulwini eluhlaza, kodwa ifomu ziye ezinye izilungiso.

Ngoko ke, ngokutsho ulwazi olutsha, oluthembekileyo ngakumbi ngalo emhlabeni, siyazi ukuba Umhlaba atshabalalisa kancinci kwi pole. Oko kukuthi, akukho sphere kodwa ellipsoid wotshintsho, okanye geoid. Ukhetho phakathi kwala magama mabini ibaluleke kuphela yokuma, geodesy, aerospace. yokubonakalisa ngamanani parameters umhlaba uya kuba yimfuneko ukuba izibalo oluchanileyo. Kwaye ngoko ukuma komhlaba iye awohluke yayo.

inkcazelo ngamanani imilo le planethi

Kuba icandelo kolwazi jikelele malunga ihlabathi ngaphezu ukusebenzisa geoid elide. Le yokugqibela, ngasendleleni, ukusuka lesiGrike ngokoqobo lithetha "into efana Umhlaba."

Kunika umdla achaza ngokwezibalo imilo Umhlaba njenge ellipsoid wotshintsho ayikho nzima. Kodwa njengoko geoid cishe kungenakwenzeka ukuba afumane iinkcukacha ezininzi echanekileyo kuyimfuneko ukuba umlinganiselo womxhuzulane kwiindawo ezahlukeneyo kulo mhlaba.

Kutheni umhlaba atshabalalisa kwi zezibonda?

Ukusuka ngasentla Ngoku siza kuqwalasela imiba ethile ethile lonke umxholo. Ngoku siyazi ukuba imilo Umhlaba enyanisweni, kuya kuba umdla ukubona isizathu.

Kwakhona: iplanethi yethu atshabalalisa kancinci kwi nezibonda, kwaye akukho sphere ogqibeleleyo. Kutheni kunjalo? Impendulo elula, kuyacaca ukuba umntu onesifo lokuqala ukuqonda nokwakheka. Xa Umhlaba ujikeleza ngeenxa axis yayo ikhweyitha kukho imikhosi centrifugal. Ngako oko, izibonda zazo asinakuba. Kwaye kwasekwa umahluko kwi kwirediyasi sentshinyela polar kunye: Last elide kwindawo ethile km 50.

Komzila Umhlaba: yintoni imilo na?

Njengokuba sisazi, le planethi lijikeleza kuphela axis kwayo, kodwa wenza i uhambo olude kumbindi kwenkqubo elanga. Ingaba komgca wentelekelelo apho ihamba esithubeni, ekuthiwa komzila. Siye safunda, yintoni imilo yiplanethi uMhlaba. Kwakhona bafumanisa ukuba umbane uwuthenge lwezityalo.

Kodwa yintoni fomu wenza ukujikeleza komhlaba? Yena wenza ujikeleza ilanga kumendo okweqanda, ukuba ngamaxesha awahlukeneyo imigama ezahlukeneyo ukusuka elangeni. Yokuba kwindawo ethile komzila kuxhomekeke ixesha emhlabeni.

State xa qelele umhlaba ukusuka elangeni, ekuthiwa aphelion, into osondele kakhulu kuyo - perihelion (amagama amabini ka imvelaphi Greek).

Umelo kwemiphakathi yamandulo

Ekugqibeleni kukhanye inqaku imifanekiso zethu eliqaqambileyo nengqikelelo esiye wachaza ababengaphambi empucuko mihla. Fantasy kubo, kufuneka ukuba athi, kwaba mnandi.

Ukuze lo mbuzo, "Luhlobo olunjani imilo i Umhlaba?" yamandulo eBhabhiloni bambalwa ukuba yintaba enkulu kwelinye kwamathambeka leyo ilizwe labo. Ngaphezu oko amajukujuku - zezulu, kwaye kwakunzima nje eweni.

I AmaNdiya baqiniseka ukuba umhlaba isekelwe phezu iindlovu zine, esibambe ufudo emqolo, idada lulwandle yobisi. Ulwalathiso iintloko Elephants - iingongoma ezine zekhampasi.

Kuphela BC 8-7 leminyaka. e. ngcembe abantu baye bafikelela kwisigqibo sokuba umhlaba - into eyahlukileyo ezivela macala onke, yaye emi kule nto. Kuye ebusuku kwenza yokuduka kwelanga, phambi apho kuvavanywa ukumangala.

isiphelo

Lwaba ethetha, uMhlaba - ngeenxa zonke. Ukuze ongenalwazi oku kuya kuba ngokwaneleyo, kodwa hayi ngenxa yenkcazelo yesayensi. Xa geodesy, aerospace, isayensi kufuneka iinkcukacha ezichanekileyo ukuze izibalo. Kwaye apha kubalulekile impendulo ngqo lo mbuzo, yintoni uhlobo enceda umhlaba. Kwaye geoid okanye ellipsoid wotshintsho. Planet phantsi kweempembelelo imikhosi centrifugal atshabalalisa kwi pole. Thatha ingqalelo idata ngqo kwi planethi kubalulekile ukufumana izibalo ezichanekileyo.

Long ingasekho amaxesha xa umhlaba wanikela ukuya ngasemva okanye amelwe iindlovu kumphezulu wayo tyaba. Makhe abazinikele e inyaniso ngehlabathi yaye sihlala ufanelwe ngexesha lazo!
