Mvura yegungwa inomiririra kusiyana-siyana kwakakura kunofukidza chikamu chikuru chepasi. Muchinyorwa chino, uchawana zvese zvaunoda kuziva nezvemvura yegungwa: hunhu hwayo, kukosha kwayo, mafambiro ayo, nzvimbo yayo, nezvimwe. Huyai musapotsa chero chinhu!
mvura yegungwa
Mvura yegungwa ine simba rinoshamisa rekufukidza 70% yenzvimbo yepasi. Izvi zvinoreva kuti huwandu hwayo hwakanyanya, zvichireva kuti pasi rine mvura yakawanda inofukidza nzvimbo yakakura yenzvimbo yaro.
Kubva kare, dzidziso dzakawanda nefungidziro zvakabuda kuti zviongorore mavambo emvura yegungwa . Imwe yefungidziro dzinogamuchirwa nevakawanda ndeyekuti mvura idzi dzakatanga makore angangoita mabhiriyoni mana apfuura.
Tsananguro yake inobva pamabasa okuputika kwemakomo uye kuwedzera pakupisa kwakanyanya kwakaitika mukati menguva iyoyo yegore rataurwa pamusoro apa. Nekuda kwezvinhu zviviri izvi, fungidziro yekusikwa kana mavambo emvura yemugungwa inomuka. Asi ikoku kwakabvira sei? Icho chokwadi chinovakwa nekuda kwekuti munguva dzekuputika kukuru kwegomo kunoperekedzwa nekupisa kwakanyanya.
Iyo huru polar caps yakanyunguduka zvishoma nezvishoma uye zvishoma nezvishoma, izvo chando chakashandurwa kuita mvura yakafashukira uye ichitevedzana ichienda kune dzimwe nzvimbo kana nzvimbo dzepasi.
Nekuda kweizvi, kupatsanurwa kwemakondinendi kunobva, izvo zvakare, parizvino zvinoperekedzwa nezviwi zvakasiyana-siyana, dzimba mukati mavo, huwandu hwakawanda hwemhuka. Nechikonzero ichi, kuchengetedza nzvimbo idzi chave chinhu chakakosha kune vakawanda.
Sezvo pari zvino kune zviito zvakawanda zvekusvibiswa zviripo mumvura yegungwa pasi rose, izvo zvakakanganiswa nehuwandu hwezvinhu zvinokuvadza kune zvakatipoteredza.
Mvura yegungwa inoonekwa seimwe yezvisikwa zvakakosha zvehupenyu pasi pano, kunyangwe kubva pakutanga kwayo. Yakagadzirwa nemvura yakawanda, iyo zviri pachena kuti ine huwandu hwakawanda. Kune makungwa mashanu anotsigira hupenyu pasi pano parizvino; aya ndiwo anotevera:
Pacific Ocean
Iyo ine nharaunda inosvika zana nemakumi masere nesere miriyoni square kilometres.
- Atlantic Ocean
Iyo ine nharaunda inosvika makumi mapfumbamwe nemana emamiriyoni emativi emakiromita.
- Indian Ocean
Iyo ine nzvimbo inosvika makumi manomwe nemana emamiriyoni emativi emakiromita.
- Antarctic
Iyo ine nzvimbo inosvika mamiriyoni makumi maviri emakiromita emakiromita.
- Arctic Ocean
Iyo ine nzvimbo inosvika miriyoni gumi nemana square kilometres.
Mune ino post, tinoda kukukoka iwe kuti unakirwe neruzivo uye ruzivo rwakapihwa pano, iyo yatinovimba ichave yekuda kwako, uchifunga kuti ichi chinomiririra chinyorwa chakakosha chekuchengetedza nharaunda dzedu.
Hunhu hwemvura yegungwa
Mvura yegungwa ine hunhu hwakakosha zvikuru, sezvo ichitibvumira kunzwisisa mashandiro ehunhu hwayo uye mamiriro echisikigo anozvitsigira. Pakati pehunhu hwakakosha ndeidzi:
mafungu egungwa
Idzi itsime rinokosha rinozviratidza mukufamba kwemvura yegungwa . Hunhu hwadzo hukuru ndehwekuti dzinogara dzichifamba nekuda kwekumanikidzwa kwemhepo dziri munzvimbo dzegungwa kana nzvimbo.
Ikozvino kune kusiyana-siyana kwemhepo, iyo nekuda kwezvidzidzo, yakapihwa akasiyana-siyana emhando yepamusoro, ayo anoreva mazita emarudzi, muenzaniso weizvi:
- Iyo East Australian Iyezvino
- California yazvino
Imwe neimwe yeaya mafungu anokura padyo nenzvimbo dzenyanza, izvo zvakare zvinokanganisa zvakanyanya shanduko yemamiriro ekunze aripo munzvimbo dzavari pedyo.
- Waves
Inomiririra chinhu chaicho chechimiro chemvura yegungwa, masaisai, tenda kana kwete, akakosha chose, anozadza mvura inotambanuka yakananga kumahombekombe akasiyana semabhichi nehupenyu. Izvi, zvakare, zvinokanganiswawo nekuda kwekukukurwa kwekusingaperi kunotanga, kuburikidza nemasaisai mamwechete, anoedza kuumba pamusoro pemahombekombe.
- Mafungu
Ongororo dzakadzama dzakaratidza kuti mafungu anowanzokonzerwa negiravhiti rinobudiswa nemwedzi, uyewo nezuva. Izvi zvinozadzisa basa rekuona, uye rinochengetedza mutinhimira chaiwo waunogona kuyera nawo kukwira nekudonha kuripo mumvura yegungwa. Gare gare tichave tichitaura pamusoro pekukosha kwemvura idzi pamwero wakajairwa kune nyika yaamai vedu.
Zvinhu zvemvura yegungwa.
Pamusoro pezvambotaurwa hunhu hwemvura yemugungwa, isu tinofanirwa kuratidza kuti ndezvipi izvo zvinhu zvinoitsanangura mukurova kukuru nguva dzose, zvinhu izvi zvinotibvumira kuwana ruzivo rwese nezve zvimwe zvezvinhu zvinogadzira, izvi zvinotevera:
- Kudzika
Kudzika kwemvura yegungwa kunoenderana nerudzi rweruyamuro rwunotarisa dunhu riri kutaurwa, zvisinei, rinogona kusvika kusvika zviuru zvitatu nemazana mapfumbamwe emamita.
- Tembiricha
Kana iri nzvimbo dzine mhando yemvura inodziya, idzi dzinowanzoiswa pakati pe10 ne29°C, uye mune dzimwe nguva dzinogona kubva pakati pe5 kusvika -1°C.
- Munyu
Izvi zvinomiririra chimwe chezvinhu zvakadzidzwa zvakanyanya zvemvura yemugungwa kazhinji. Iyo inoumbwa nezvikamu zvemakemikari, senge sodium chloride, inovhara zvishoma makumi mapfumbamwe kubva muzana ezvikamu zvakasiyana zvakanyungudutswa mumvura yakataurwa.
Nekudaro, chloride haiite yega, inoperekedzwa nezvinhu zvinotevera:
- Sarufa
- Calcio
- Magnesio
- Potasiamu
Sechokwadi chinocherechedzwa, kuwanda kwemvura dzemunyanza kwakasiyana kune yakanyanya kuwanda kupfuura nzvimbo yemvura yakachena. Naizvozvo, inofungidzirwa kuti inogona kuwana density yeanenge chiuru makirogiramu pacubic mita. Nekuda kwemhando iyi, mvura idzi dzine chivakwa chinonakidza chekubvumira miviri yakasiyana kuti irambe yakayangarara mukati memvura ine munyu iyi.
Kana iri hue yemvura idzi, ine bluish zvachose, izvi zvinokonzerwa nekunyura kukuru kunoitwa mvura, nekuda kwechiratidziro chinochengetedzwa pamwenje dzvuku, zviratidziro izvi zvinobva kune mamwe mamorekuru anogamuchira mwero wakati wezuva. izvowo, zvinopedzisira zvave kuratidza bhuruu yegungwa.
Kukosha kwemvura yemugungwa
Mvura dzemugungwa dzakakosha zvikuru pasi rose, dzichimiririra nzvimbo yakakura yepasi rose ine basa rakakosha. Saka, tinofanira kupemberera nemufaro kukosha kwemvura dzemugungwa.
Muhudzamu hwayo hwakakura uye hukuru, zvinofanirwa kucherechedzwa kuti mumvura yegungwa mune mhando dzakawanda dzemhuka dzinogara mukati megungwa, kwete kungoshongedza nharaunda chete, asiwo kuzadzisa hurongwa hwekuchengetedza nharaunda hunoenderana nahwo .
Mvura yega yega yegungwa iri mumamiriro akakodzera kutakura mavhitamini anodiwa kumhuka dzakawanda dzainogara. Zvinovaka muviri izvi zvinogona kushandurwa kuita manyuko emiti yakarongeka zvakanaka. Izvi zvinodaro nekuti mvura iyi nhasi ine mhando dzakawanda dzemhuka dzemumahombekombe.
Kudzora kwepuraneti ndeimwe yekukosha kwemvura yemugungwa pasi rose. Tichifunga kuti vanokwanisa kudzora huwandu hunodiwa hwekabhoni dhaikisaidhi uyezve okisijeni inowanikwa mumhepo yepasi redu. Sezvatakambotaura, izvi zvakare zvine hunhu hwekutsigira huwandu hukuru hwemhuka dziripo munzvimbo yadzo.
Zvinofanira kucherechedzwa kuti mumvura yegungwa hamuna kusiyana kukuru kwezvipenyu, sezviri mune mamwe marudzi emakungwa.Zvisinei, anogarwa nemhuka dzakanyatsogadzirirwa kutsigira rudzi urwu rwe megadiverse ecosystem. Pakati pavo tinogona kutaura:
- Whale
- Octopus
- Jellyfish
- gumbeze rine mitsetse
Ndidzo dzimwe dzemhuka dzinoita hupenyu mumvura yegungwa, iyo inochengetedzwa pane yakakwana uye inoshanda inogadzirisa system. Sezvo vachigara munzvimbo idzi netarisiro huru.
Nekudaro, kune zvakawanda zvinokonzeresa kana kukanganisa izvo mvura yemugungwa inogona kuunza pasi rose, sezvo mafungu ayo anogona kuve akanyanyisa mamiriro ezvakatipoteredza, ayo ane mhedzisiro yakaipa iyo inogona kukanganisa zvakananga seti yese yezvipenyu.
Kuve mvura kana mafungu emugungwa, nguva zhinji, avo vane mhosva yekuvandudzwa kwezvinhu zvikuru zvechisikigo, senge:
- Madutu
- Mafungu emvura
- Madutu
Naizvozvo, kukosha kweizvi, kune huremu hukuru, maererano nemabasa ainopa kupasi rose. Kuve nemutoro wehuwandu hukuru hwezvakasikwa zvatinogona kuona zviri nyore.
Aya ndiwo mamwe maitiro uye kukosha kwemvura yemugungwa. Isu takatoziva zvimwe zvezvinhu zvakatanhamara zveiyi nyaya inonakidza. Tinovimba kuti ruzivo urwu ruchabatsira zvikuru pakutsvaga kwako. Tichifunga kuti ruzivo rwakakwana kuitira kuti iwe uwane ruzivo rwakakosha nezveiyi nyaya inonakidza.
