Yintoni ebusika? Uhlalutyo olunzulu

Eli nqaku lichaza ukuba le ebusika, oko kukuthi, kuxhomekeka kwindawo emhlabeni, yaye kutheni kukho amaxesha ukutshintsha.

Ubomi emhlabeni apho, ngokutsho izibalo izazinzulu ', kwiminyaka engaphezu kwama-3 billion ubudala, yaye kwinkqubo yethu ilanga, kuphela Umhlaba nethamsanqa ukuba iimeko ezithile ukwenzela uphuhliso kunye nolondolozo ubomi eziphilayo. Ezo zinto zininzi. Oku kunye nobukho amanzi elulwelo, umgama elithile ukusuka inkwenkwezi engundoqo, ubunzulu, emoyeni, njalo-njalo. N. Kodwa, kukho enye into, oko ukujikeleza umhlaba bethu axis yayo, apho kukho utshintsho onyaka. ahlobene njani? elula kakhulu, khangela umzekelo phephandaba efanayo. Le iplanethi lisondele kakhulu ilanga, yaye, ngaphandle, usoloko yaba icala elinye, nto leyo esisizathu sokuba kwicala enelanga obushushu ekufikelelwe phantse 500 degrees Celsius kwaye ebusuku ungukumkani ubumnyama obungunaphakade kunye nendawo ebandayo. Ngoko ke, njengokuba ubona, onyaka ibalulekile kakhulu. Kwaye kule meko sithetha ebusika. Ngoko ke, yintoni na ebusika?

definition

Okokuqala, makhe ukujamelana ngokwalo. Winter - oko ngexesha kuyabanda, ngexesha apho ubushushu kugcinwa esitalini ngaphantsi kweqondo zero Celsius yaye ngokufuthi selikhithika. Ukuba uthathe le khalenda ebusika kumntla ikhweyitha, it ihlala iinyanga ezi-3 - Disemba, ngoJanuwari noFebruwari. Nakwelasezantsi - Julayi, Juni no Agasti. Ngoko ke, ngoku siyazi ukuba ubusika. Noko ke, kutheni na apho?

Ukuthambekela esqwini

Yonke le ndaba ubucukubhede yasezulwini, enyanisweni, njengoko umhlaba ujikeleza. Nge periodicity ethile Umhlaba yahluka ukuthambeka yezihlunu ngokumalunga moya ka baza, ngokuba kumntla ikhweyitha ifumana ubushushu ngaphantsi elanga, ngenxa yoko iqondo lobushushu avareji ebegqwese ubuza, xa ukumelana wayo ngezantsi 0 izidanga kwaye iqala ixesha elililo eqhelekileyo. Le nto ibizwa ngokuba ebusika ngeenkwenkwezi kumntla ikhweyitha isebenza ukususela ngoDisemba 22 ukuya kuMatshi 21. Ngoko ke, siye saxubusha umbuzo wokuba yintoni lasebusika.

sezulu

Nangona usuku nekhalenda ngeenkwenkwezi zasebusika, ixesha abandayo kunye lobushushu ezingakhiyo imvula yonke yenzeka ngeendlela ezahlukeneyo. Umzekelo, kwilali Russian ka Oymyakon, ukuqalela ku-Agasti 31, iithemomitha rhoqo ukubonisa amaqondo ezimbi, oku kwenzeka ngokufanayo neminye imimandla Yakutia kunye Chukotka. Kaloku, Primorye kunye nommandla iyavuma ngenxa kufuphi kolwandle, isimo sezulu sisiba kubanda beze, ngokulandelelanayo, kamva.

Ukuhlalutya umbuzo yintoni ebusika, kufanelekile ukuba sikhankanye imisinga olwandle, nto leyo badlala indima ebalulekileyo kwimozulu. Umzekelo, i-Netherlands, nto leyo uhlanjiweyo yi-Gulf Stream na imozulu olulamileyo epholileyo, nangona Chukotka enye, lo gama phantse kwi ngama enye, ohluphekayo inkoliso yonyaka evela yeqabaka kakhulu kunye nemvula.

ihlobo engunaphakade

On Earth, kukho imimandla apho soze ebusika. Yaye isibakala sokuba abantu balapha uthathe ngenxa yengqele, ukuba nje uncumo kwi abemi kumntla ikhweyitha, kwaye --ikhweyitha. Kwakhona, ngenxa ukuthambeka of axis koMhlaba, ukutshintsha amaxesha onyaka apho phantse lungenzeki, kodwa kwenzeka rhoqo ngexesha lemvula.

imini Polar nobusuku

Zombini ngasentla kunye emazantsi, kukho ezimbini ngumkhuba umdla kakhulu ubusuku polar nemini. ebusuku Polar na ixesha xa ilanga ayisekho ngosuku, kunye imini into efanayo, kuphela umva - xa ilanga akumenzi iiyure eziyi-24. Ubude bexesha la buxhomekeke kakhulu ngexesha lonyaka kunye inkululeko, kodwa xesha lide ebusuku polar sisaqhubeka phantse ezintandathu iinyanga rhoqo.

Nangona isibakala sokuba abantu baphile ixesha elide bezenzeko ezinjalo, Basaba nefuthe umntu abe engqondweni nasemzimbeni. Ebudeni abantu ebusuku basoloko ingaba unokudakumba ebonakalisiwe yokunqongophala kakhulu novithamini D.

Ngoko ke, simele siqonde ukuba ubusika, inkcazelo ilizwi njengoko ingqalelo.
