Kutheni uMhlaba ibizwa blue? Yinyaniso le?

Ngasinye Ngokuqinisekileyo Ndakha ndeva ukuba Umhlaba kuthiwa "umhlaba eluhlaza". Umhlaba wafumana lo gama ayikho elide kangaka elidlulileyo, ngenxa yokuba abantu ngaphambili nje abazange babe
ithuba ukuze ubone iplanethi yethu bemgama, ukuba sibe nentembelo ngebala zalo ezisisiseko. Kodwa ngaba uqinisekile ukuba kanye khumbula kutheni umhlaba
Umhlaba ibizwa eluhlaza?

ukuvela

Amanzi kwindalo iphela ibisoloko. Ewe, ekuqaleni kwakungelilo amanzi, kodwa kuphela molekyuli zincinane ezifakwe kwi isibi uthuli kunye kwimibutho eyahlukeneyo yasezulwini.
Emva kwethutyana, la amasuntswana othuli nomzimba emanyeneyo kwimfundo elinye elikhulu, wabumisela ukuze sibe uMhlaba.

Ukhangela kwi ekhaya lethu iminyaka 4.5 billion kuphela eyadlulayo, akukho bani ongaphinda niqashele kutheni uMhlaba kuthiwa eziluhlaza. Ngapha koko, ukuba isiqwenga omkhulu abilayo ngumash kunye iqhuma mlilo. Kangangamawaka eminyaka iigesi wakhululwa xa besenza ezi nkqubo, ukusekwa ojikeleze umhlaba. Kwakukho methane, ne-nitrogen kunye emanzini, yehayidrojini kunye carbon dioxide. Hayi kuphela apho mpilo.

Wayengenguye nje kweminyaka engama eziibhiliyoni ezi-4 edlulileyo kancinane, emoyeni lupholile phantsi degrees 100 - ke inkqubo amafu ekugcineni sibini
Tyhila enamanzi. amathontsi Endless, ukutshiza, ukuhamba yonke le yamanzi ziwe eMhlabeni. isiphango Incredible bangene kwiplanethi yethu
kangangamawaka eminyaka. Kwakukho ngokoqobo umkhukula! imilambo Phantse engaphele abilayo imvula phezu komhlaba. Okokuqala, nemisinga, umlambo ke omkhulu kakhulu
ungena endaweni enye, ngokuthe ngcembe siwenze elwandle. Noko ke, ngoko ke amanzi amdaka ampompozayo ukusuka kubushushu kunye rhoqo
ukugcwaliswa. Yaba kuphela emva amakhulu ezininzi iinkulungwane amanzi ezilwandle baqalisa ukucoca, apholileyo, oko kukuthi, wathabatha umbono ukuba sikwazi ukubona namhlanje.

Amanzi - oku ke into, nto leyo yenze iplanethi yethu ezizodwa kwaye kwenze ukuba sikwazi ukuxhasa ubomi uMhlaba.

iplanethi blue

Oosomajukujuku bathi xa ujonga Earth umhlaba ukusuka yisathelayithi, okokuqala zonke sinikele ingqalelo nombala oluhlaza. Oku kungenxa yokuba iimpawu zethu
Umoya kunye kumphezulu planethi (kuphela apho amanzi ngohlobo wamanzi). Ukongeza, iplanethi yethu ukhetheke kukho ioksijini
emoyeni kunye ozone zokhuseleko umboniso ethintela iziphumo ezibi ye imisebe iinkwenkwezi. Namhlanje, ukuqinisekisa ukuchaneka oosomajukujuku, ngokwaneleyo
nje ukuba ubone iifoto ukusuka yisathelayithi yehlabathi.

Ocean umbala

Kwelinye icala, ndiyamangala ukuba kutheni uMhlaba ibizwa emsi, ngokuba amanzi akukho mbala. Noko ke, inkoliso kwamanzi olwandle ukuba abantu
Ndikugqala oluhlaza. Ngamanye amaxesha ulwandle kunokuba eluhlaza, omnyama okanye omthubi. Yintoni ingxaki?

Kwaye isizathu ilula: ke umbala amanzi sibona ukukhanya kwelanga. Kodwa nayiphi na ray, njengoko yaziwa, iquka yonke imibala yomnyama. ubude wave for umbala nganye yahlukile,
ngokulandelelana, aze angene kwikholam emanzini zinokuba kubunzulu ezahlukeneyo. Ombala imfutshane umbala obomvu, elide - oluhlaza. angala
Ngenxa yesi sizathu, amaza imibala eyahlukileyo ziboniswe ngeendlela ezahlukeneyo. Kwaye usinika ithuba ukubona elwandle imibala eyahlukileyo.

Kakade ke, kusekho lulwandle ebomvu, kodwa ibali ngabo - ukuba ibali eyahlukileyo ngokupheleleyo, kuba umbala yabo ngenxa yenani elikhulu ulwelwe ebomvu
phezu kolwandle, kunokuba ezinomlinganiselo yamanzi kwelanga.

ulwandle blue

kubunzulu Ukungena ukukhanya elwandle ixhomekeke ecace kwamanzi. ukukhanya kubonakala ukusuka amasuntswana ezincinane ezifana ulwelwe okanye amasuntswana ezikhoyo
kuyo nayiphi na elwandle ngohlobo zokumiswa. Umphantsi nomphezulu ezilwandle kunye yeelwandle engenabutyebi zezi amasuntswana, njengoko bawe phantsi. Ngenxa yesi sizathu, inxalenye oluhlaza spectrum yi
ithuba lokucinga anzongonzongo kakhulu.

Zonke iilwandle tropical ukuqhayisa microalgae, ngoko umbala yaye zonke emsi, ukuba ukhangela uMhlaba evela satellite okanye zamawa.

ngombala owahlukileyo

Amanzi kweelwandle, ecingisisiweyo lobushushu rhoqo okanye esebenzayo ngexesha ngokuqhubekayo engumxube, usazisa inani elikhulu lamanqanaba eliphezulu
izondlo. Amanzi ngenxa yesi sizathu, kubonakala zinodaka kakhulu ngakumbi, unako ukungena ngaphaya nomphezulu ukukhanya kwelanga, ngoko akukho reyi blue
ezirekhodiweyo. Umbala amanzi ayehluka luhlaza mdaka.

Kubonakala, kutheni uMhlaba ibizwa emsi, ukuba umbala yolwandle kuzo zonke iindawo ezahlukeneyo? Inyaniso kukuba xa usibona satellite elangeni
Oku kuboniswa kuphela ngamanzi kodwa ngokwayo udlula emoyeni. Kwaye kanye kule umoya umqadi nalo lubonakala ikakhulu kwi spectrum oluhlaza. Kakade ke,
kukho amafu emhlophe olephuzayo; kodwa oku nje lutyhido zamahlathi kakhulu umphunga wamanzi, ezo ayikwazi ezidlulayo zamaza. Apha ulibonakalisa kunye namanzi, umoya kunye nombala eliqaqambileyo eziblowu kwaye sibona imifanekiso zomhlaba.
