Nei gungwa wakawanda

Sezvo makarekare vanhu kutsvaka mhinduro yomubvunzo wokuti sei gungwa munyu. Kutaura zvazviri, izvi ane yeshoko mvura yose mumakungwa uye nyanza, chete salinity pamwero yakasiyana munhu wose. Kubva indekisi ichi zvinoenderana zvipenyu zvakasiyana-siyana pane gungwa.

Asi kutanga munyu. Ndepapi parinotaura zvinobva? Zvino ivhu, matombo uye ibwe nezvimedu zvine munyu siyana uye vasanaiwa nemvura navo urwa. Mvura Hova anodirana kurwizi, vari tudonhwe munyu mugungwa. A mberi zvose sezvo kuchikoro bhuku: chezuva kunoitika kuti kwemvura rikurumidze (mvura runopwa uye munyu rinoungana mukati megungwa) uye muchimiro kunayisa nayo anodzokera zvakare panyika, kugeza kunze munyu kubva ivhu nezvimedu ...

Asi ichi ndicho chete chikamu mhinduro yomubvunzo wokuti, "Nei gungwa wakawanda." Chimwe chikamu unofanira kutarisa pasi pegungwa. Ndicho murwiyo pegungwa, asi kubva pamatombo kuti zvinoumba nayo, ari salinity yegungwa anoenderana zvinhu zvakawanda. Makemikari anoumba mvura yegungwa kusvika haachinji, uye kubva gungwa neimwe kana yomugungwa ane wake, vagere yakadzika gungwa vanokwanisa kurarama, somunhu ushe, chete nenyika yaro. Havagoni kufamba kubva mugungwa mumwe. Uyewo zvikuru ndiyo kwemvura mwero - dzakanga ndiro, ndipo yakaomerera munyu mvura mugungwa.

Kazhinji, pane zvikonzero zvakawanda chokuita salinity pamusoro pegungwa. Somuenzaniso, musi Sea Black salinity inobata penyanza remoteness uye kuti European zvakadzama nzizi dzakawanda kutakura mvura yavo pano. Huge kuyerera yekudyidzana akazoita padanho salinity, zvinoita kuti vasanyanye zvipenyu kweGungwa Dema. In tichienzanisa uwandu vagere Gungwa reMediterranean Black pakadzika vari zvikuru mwero, uye zvakasiyana-siyana ari murombo; pano musingadi kusangana Starfish uye urchins, cuttlefish uye octopus, dzichibhururuka hove uye Squid. Nemiti kweGungwa Dema ndiyewo yekudyidzana varombo.

Nei gungwa wakawanda? Pane imwe nguva, kuvapo risingagoni kungotariswa pakupindura mubvunzo uyu - mapindu, kushambidzwa pagungwa kana gungwa. Sezvaunogona kuona, mhinduro hakusi nyore sezvo zvingaita sokuti pakutanga kuaona.

Achienzanisa Black uye Mediterranean makungwa, mvura yavo nyika, chaiva chokupedzisira ari nani, nokuti mukuru salinity revarombo. Uye chii chinonyanya wakawanda gungwa munyika? Mhinduro yomubvunzo uyu nyore - Red. Kana Sea Black munyu tigutsikane - ipapo muGungwa Dzvuku, nhamba iri kupfuura nguva maviri yakakwirira - 35-41 magiramu por fő (zvichienderana pamahombekombe) - akaenzana magiramu 17 chete fő mvura (shanu chete magiramu muGungwa reBaltic).

Izvi imhaka zvikurukuru kushaya nzizi inoyerera kupinda Dzvuku, uye vanozivikanwa kutakura mvura yakachena iyo iri imwe nzira dilutes zvomumvura achidzikisa munyu wevasungwa. Pano, wevasungwa iri zvishoma nezvishoma asi zvishoma nezvishoma kuwedzera. The denser mvura akaturikidzana vari akadarikira pazasi, mvura inotonhorera anomanikidzwa muimba akaturikidzana, akatakura rwokuzvarwa vaiitawo. Uyezve, kushaya nzizi inobvumira mvura gungwa kuramba yaro pachena uye kutsvinda. Uye kubva pane izvi zvikuru pakuti kupfuma wenyika pemvura nyika; siyana uye runako Gungwa Dzvuku, vagari kunoshamisa.

Kupindura mibvunzo pamusoro sei gungwa munyu, uye gungwa wakawanda kwazvo, hazvibviri haana kurangarira vakafa, iyo, kana zvikasabudiswa, anonziwo mudhamu. Zvikuru yakakwirira Kuwanda munyu mumvura riri kuramba akaramba ayo chicherwa zvitubu, izvo kuti mvura kwete wakawanda chaizvo chete, asi kungoti nemamwe wayo akafanana, zviri nemamwe. Hazvina mvura, uyewo kuzivikanwa silt madhaka, izvo, sezvinei, anewo yakakwirira chicherwa kugutsikana, kufarira pamhenderekedzo kweGungwa Rakafa , mazana ezviuru zvevashanyi vanobva munyika yose kuvandudza utano hwavo.
