Planet Earth inozivikanwa nemamwe mazita akaita seblue planet. Ndiro chete pasi rinozivikanwa pasi rose kuti richengete upenyu. Izvi zvinodaro nekuti iri kure chaizvo kubva kuzuva kuti itsigire tembiricha inogona kutsigira upenyu sezvatinohuziva. Zvisinei, vanhu vakawanda vanoshamisika Nei Pasi richinzi pasi rebhuruu?.
Muchinyorwa chino tichakuudza pamusoro pezvikonzero zvikuru nei Nyika ichinzi nyika yebhuruu.
Nei Pasi richinzi pasi rebhuruu?
Nyika inonzi nyika yebhuruu nekuda kwekuwanda kwayo kwemvura, iyo inogona kuonekwa munzvimbo huru yebhuruu. Nzvimbo yePasi inosvika 510 miriyoni square kilometers, iyo inopfuura 70% yakafukidzwa nemvura. Ruvara rwebhuruu runoisiyanisa kubva kune mamwe mapuraneti akadai saMars, Mercury, Jupiter, Uranus, nezvimwe.
Mvura zhinji yepasi rebhuruu yakaomeswa nechando kana kuti ine munyu, uye chikamu chidiki chete chinokodzera kudyiwa nevanhu. Makungwa makuru iAtlantic Ocean, Pacific Ocean, Indian Ocean, Arctic neAntarctic.
Kunyangwe kudzika kwemakungwa kuchisiyana munzvimbo dzakasiyana, chikamu chikuru chepasi redu hachina kumboongororwa nekuti chiri pakadzika kwemakungwa. Zvichiri zvakaoma kuti vanhu vashandise tekinoroji yavo yese kuti vakwanise kuidzidza yakazara.
Mvura yakakosha iyi inongowanda paNyika, uye hazvibviri kuwana zviratidzo zvekuvapo kwavo mune chero rudzi rwemamiriro emuviri mune yedu solar system. Maererano netsvakurudzo yakaitwa kusvika pari zvino, hapana imwe nyika ine makungwa uye oxygen yakakwana kuti itsigire upenyu.
Ruvara rwebhuruu rwemakungwa
Nyika ine makungwa makuru mashanu: Pacific Ocean, Atlantic Ocean, Indian Ocean, Antarctic Ocean uye Arctic Ocean. Nyika yedu inoonekwa kubva muchadenga sedenderedzwa rakakura rakazadzwa nemhando dzakasiyana dzebhuruu dzakagadzirwa nemakungwa ese aya, imwe neimwe iine ruvara rwakasiyana uye hunhu.
Ichi ndicho chikonzero chikuru chakaita kuti Nyika itange kunzi nyika yebhuruu, zvisinei, yakanga isiri mvura yakapa iyo ruvara. Mvura haina ruvara, uye kunyange zvazvo ichidavirwa kuti inoratidzira ruvara rwedenga, inooneka yebhuruu bedzi nokuda kwokuwanda kwemvura, uye kupenya kwechiedza kunonetsa kupfuura namo, sezvinoitwa negungwa.

Tsvuku, yero kana yegirini ine mafungu akareba kupfuura bhuruu, saka mamorekuru emvura anoatora zviri nyore. Bhuruu rine hurefu hupfupi, saka mvura yakawanda iripo munzvimbo yechiedza, iyo yakawanda yebhuruu ichaonekwa. Zvinogona kutaurwa kuti ruvara rwemvura rwakabatana nekusimba kwechiedza, uye mune dzimwe nzvimbo zvinowanzoitika kuti hue yemvura ichinje kune yakasvibirira.
Izvi zvine chekuita nekuvapo kwealgae, kuswedera kumahombekombe, kubvongodzwa kwegungwa panguva iyoyo, uye marara akasiyana-siyana anowanzo kuwanikwa mumvura anosimbisa ruvara kupfuura bhuruu.
Iyo inozivikanwa zvakare kuti phytoplankton, utachiona hunogara mumvura hunoita basa rekupa inenge hafu yeokisijeni inofema nevanhu, chikamu chinokonzera kuchinja kwemavara emvura.
Phytoplankton ine chlorophyll uye iri munzvimbo dzisina kudzika dzemuviri wemvura kutora chiedza chakawanda sezvinobvira. Kana dzose dzakanangana munzvimbo imwe chete, gungwa rinoshanduka rakasvibira zvikuru panzvimbo peruvara rwebhuruu.
Sei Nyika ine bhuruu kana ichionekwa kubva muchadenga?
Nyika yakanga isiri nguva dzose yebhuruu, chaizvoizvo, yakachinja zvikuru pamusoro pemamiriyoni emakore yave iripo. Pakutanga, kuumbwa kwemhepo yePasi kwakange kwakasiyana chaizvo nezvazviri nhasi: mhepo inoita kuti denga, Nyika, kana Nyika iite sebhuruu kubva muchadenga. Kuputika kwemakomo kunogara kuchiputika panyika yedu kunobuditsa huwandu hwemhute yemvura mumhepo, iyo inozopedzisira yaumba makungwa painogadzika.
Mumakungwa iwayo, algae akatanga kuberekwa uye kukura. Dzinopedza carbon dioxide uye dzinobudisa oxygen. Kana tikafunga kuti carbon dioxide yakanga yakawanda panguva iyoyo uye kuti kwakanga kusina mhuka dzaidya oxygen, kuwanda kwealgae nemazana emakore kwakakwanisa kushandura kuumbwa kwemhepo yakapoteredza pasi kusvikira yasvika nhanho dzakafanana nedzatiri nhasi. .
Chokwadi ndechekuti kana tichitarisa denga masikati rine bhuruu, Chinhu chimwe chetecho chinoitika patinocherechedza pasi kubva muchadenga, mhepo yakapoteredza pasi inotipa ruvara rwebhuruu. Izvi zvine zvakawanda zvekuita nekuumbwa kwemhepo yedu uye dzidziso yechiedza.
Kunobva chiedza panyika yedu izuva. Nyeredzi inoburitsa mhando dzakasiyana dzechiedza chatingabatanidza kuti tigamuchire sechiedza chichena. Kuti tisvike kwedu pasi 8 maminetsi abva kuzuva, chiedza ichi chinofanira kutanga chapfuura nemuzvikamu zvakasiyana zvemhepo yedu. Sezvatataura, kune mamorekuru akasiyana anoumba mhepo yedu, asi pane ese mamorekuru aya, chikuru initrogen. Hunhu hwemamorekuru enitrogen ndeokuti kana agamuchira chiedza, anochibuditsazve kune imwe nzira zvichienderana nekukura kwechiedza.
Kana chiedza chasvika muchadenga, mwaranzi yakareba (yakatsvuka, yegirini, neyero) inorova pamusoro kana kuti inobudiswazve muchadenga, nepo mwaranzi mipfupi yebhuruu inotaridzwa uye inopararira. Nokudaro, tinofunga kuti denga rine bhuruu.
Kubva rinhi Nyika ichinzi the blue planet?
Muchokwadi, zita remadunhurirwa renyika yebhuruu nderenguva pfupi yapfuura, izvo zvine musoro kana tichifunga kuti hazvina kutora nguva yakareba kudaro kubva takwanisa kuona kutaridzika kwePasi kubva muchadenga. Chokwadi ndechekuti zita iri akaita mhanza muma1960 nema1970, akave akakurumbira, uye akatepfenyurwa kusvika nhasi.
Panguva iyoyo, nyika yakakamurwa kuita masangano makuru maviri ezvematongerwo enyika neeupfumi, boka remacapitalist raitungamirirwa neUnited States uye mubatanidzwa wemakomunisti waitungamirirwa neSoviet Union. Nguva iyi munhoroondo inozivikanwa seCold War nekuti kunyangwe pakange pasina kunetsana kwakanangana, nyika mbiri idzi dzakanetsana mune zvimwe zvese zvaigoneka. Mukati meaya makore kunonzi nhangemutange yomuchadenga yakaitika, umo nyika dzose dziri mbiri dzakaedza kuva dzokutanga kuita rwendo rwomuchadenga rwakarongwa nomunhu uye kumhara paMwedzi.
Ichokwadi ndechokuti maRussia neAmerica cosmonauts akatanga kubuda mumhepo yedu uye akacherechedza Pasi akaona kuti kubva "ikoko" pasi redu rinotaridzika seguru guru rebhuruu, inyika yebhuruu.
Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezvekuti nei Nyika ichinzi nyika yebhuruu.
