Globe: ephilayo olulodwa noma ...

Globe - bekuyobonakala sengathi kungaba lula? Ngenxa azifele ndaba, eyasebenza njengodonga amabhlogo wokwakha iplanethi yethu, libuthelwa ndawonye yinhlama, futhi kancane kancane bakha sphere ephelele, futhi ukushayisana sekukhona kamuva ngenxa izinqubo zomhlaba. Kodwa iphutha amanga egameni ukuma iplanethi yethu. Ngisho noma kwabakwaIsrayeli badilize wonke amagquma atigcwalise ehlanzeni, umhlaba uyindilinga. Zokuma kwendawo nezazi izazi zezinkanyezi ziye beveza igama ibhola esiyisicaba-pole - the geoid. NgesiGreki kusho "like umhlaba." Okungukuthi, Umhlaba lesi sijame njengebhoksi Earth. Lokhu lapha uwoyela lamafutha.

Kokucindezela-pole umhlaba hhayi kuphela, kodwa futhi noma iyiphi inhlangano yasezulwini mass eyanele ukuthi uzungeza kuma-axis awo azungeze. Nokho, "geoid" - a igama elicacile, lochwepheshe. Ekuphileni kwansuku zonke, abezindaba mass nezincwadi ezidumile okuvame ukusetshenziswa elinye igama - wonke. Banikezwe Empeleni ukuba iplanethi yethu ibe isicaba-pole, selilonke lwembulunga, idwetshwa ngokusebenzisa Induku yenkabazwe, zizohluka. Umbuthano ungenisa ngokusebenzisa Kuma-pole, kuyoba amakhilomitha angaphezu kwamashumi amane amawaka, anamakhulu asixhenxe, futhi selilonke yenkabazwe - omane amawaka amakhilomitha ayisikhombisa nanhlanu. Emhlabeni jikelele, in the amakhilomitha ayisithupha nesishiyagalombili Umehluko singelutho, kodwa kwabanye izibalo ke inenani. Ingabe wake wazibuza ukuthi kungani iningi izikhungo isikhala ise Ezindaweni eningizimu? Eqinisweni kungebangelo esiyikho.

Globe heterogeneous. Ngaphansi uqweqwe kuqhathaniswa mncane efihla ingubo - obukhulu ungqimba viscous asinikeze a ka ecishe ibe yizinkulungwane ezintathu amakhilomitha ukujula. Ngezansi athambekele core ehlanganisa izingxenye ezimbili: phezulu - yangaphakathi ne liquid - okuqinile. Amazinga maphakathi Earth ifinyelela ukubaluleka degrees ayizinkulungwane eziyisithupha Celsius. Cishe izinga lokushisa owandile phezu kwelanga.

surface eMhlabeni kuyinto heterogeneous kakhulu. Ngaphezu kwalokho, izingxenye ezimbili kwezintathu elalihlala izilwandle. Ngakho namanje futhi izwe asele akuyona njalo kufanelekile ngayo ekuphileni okuvamile. Nakuba isintu ingashintshwa ukuze aphile ngisho ku kwezimo ezingezinhle eNyakatho Ekude kanye ezingwadule zase-Afrika, akukho impucuko enkulu yezizwe ayikwazanga ukudala abahlala lapho. Ngesizathu esisodwa esilula: bonke amandla aphumile ukulwa ne imvelo elibuhlungu kanye nokugcinwa amazinga esisekelo eziphilayo. Lapho lapha ukucabanga mayelana ukunwetshwa noma ukudalwa impahla, amasiko noma amagugu yesayensi!

Inani labantu emhlabeni lenzelwa phezu kobuso planethi engalingani kakhulu. Ngisho nasezikhathini zasendulo abantu abaningi babehlala ezindaweni ezishisayo, izifunda ezinesimo sezulu esihle kanye engxenyeni eseningizimu zone athokomele. Kuyinto abantu ababehlala lapho bakwazi ukwakha impucuko, okuyinto isigqoko futhi ufunde ukuthi bengayeki kuze kube yilolu suku. Ezinye ipumelelo lasendulo basishiyela bengayiqondi, nakuba amakhono abo lobuchwepheshe ayiyi ngokuqinile nanoma ikuphi ukuqhathaniswa nelethu.

Ngokwe- "Gaia ocatshangelwayo" imbulunga umele omunye superorganisms nakho konke okukhona ku ubuso bayo futhi elingaphakathi yayo, uhlelo lokugayeka kokudla, emishinini yokuphefumula kanye thermoregulation. I nokuzalwa nokufa impucuko, ukuzamazama komhlaba, izikhukhula kanye izivunguvungu - yeluhlelo ngokuthi "Ukuphila Emhlabeni". Ngakho kungaba noma ososayensi, njengoba Sekukaningi usetshenziselwa ukupholisa namudrili? Thina silinde sibone ...
