Padziko lathu lapansi muli nyanja zazikulu ndi zazikulu zikwi zambiri. Ambiri mwa iwo ndi opanda dzina, ndipo ena ndi otchuka chifukwa cha makhalidwe awo achilendo. Ndani sanamvepo za nyanja yakuya komanso yoyera padziko lapansi? Inde, iyi ndi Baikal, yomwe ili ku Altai. Kapena malo otchedwa Lake Loch Ness ku Scotland, omwe amadziwika kuti ndi monster.
Zambiri zosavomerezeka ndi nyanja zomwe ziri ndi mitundu yachilendo yamadzi - Nyanja Kelimutu, Nyanja Medusa, Chernilnoe, Asphalt, Nyanja ya Kuwala kwa Mmawa ndi Rose Lake ku Australia . Zonsezi zimagwirizana ndi zachibadwa zolakwika ndipo ziri pansi pa chidwi cha asayansi - limnologists, hydrologists.
Nkhani za Nyanja Imfa
Anthu ambiri sadziwa za kukhalapo kwa nyanja yakufa pachilumba cha Sicily - Nyanja ya Imfa. Munthu akamva dzina lofanana, sizimayambitsa mabungwe okondweretsa kwambiri, koma osati chabe. Pambuyo pake, nyanjayi ili ndi chovala choipa ndipo imabisala m'munsi mwake zinsinsi za milandu yosadziwika
Monga mukudziwira, Sicily anali "otsekemera" a mafuko a mafia, ndipo anthu ambiri osokonezeka a Sicilian Mafiosi anamaliza kukhala kwawo pansi pano - m'madzi a acid acid ku Sicily. Mulimonsemo, iyi ndi nthano ya Nyanja ya Imfa, ndipo imasungidwa ndi anthu ammudzi kuti apange mtundu. Ndipo kukhulupirira mu izo kapena ayi_ndi mwangwiro payekha.
Nyanjayo inali yoyenera kutchulidwa, osati chifukwa cha kupha anthu ambiri pamphepete mwa nyanja, koma chifukwa cha kupangidwa kwake. Asanayambe kutumiza sayansi ku nyanja, palibe yemwe adadziwa chifukwa chake dera lozunguliralo linali lopanda moyo ndipo madzi a m'nyanjayi anali oopsa kwa zamoyo zonse zomwe zinagwa mmenemo.
Pambuyo pake, chirichonse chomwe chimalowa m'nyanja chimamwalira mu mphindi zochepa. Pamphepete mwa nyanja, mamita angapo kuchokera kumadzi sangathe kuona ngakhale chizindikiro chochepa cha zomera. Nchifukwa chiyani izi zimachitika? Kodi ndi mtundu wanji wa madzi osadziwika omwe umapangitsa kuti ukhale wowopsa?
Chifukwa chiyani nyanja ya imfa imapha?
Chifukwa cha asayansi ambiri amene amayesa mobwerezabwereza, pangozi ya miyoyo yawo, kuti aulule chinsinsi cha nyanja yakufa, zinali zotheka kudziwa kuti chifukwa chosowa moyo pano ndi sulfuric acid. Ili m'madzi a m'nyanjayi mwa kuchuluka kwakukulu kotero kuti ngakhalenso tizilombo tosavuta, zomwe zimapitirizabe kukhalabe m'miyoyo yosiyanasiyana, zimaphedwa nthawi yomweyo. Zinali zotheka kukhazikitsa kuti asidi a sulfuric alowa m'nyanja ziwiri kuchokera pansi pa nthaka.
Nyanja ya sulfure ku Sicily ndi Nyanja yoopsa kwambiri pa Dziko lapansi. chifukwa si madzi okha omwe ali ndi poizoni pano, koma mpweya wokha uli wodzaza ndi mvula yakuda yakuuluka. Ngakhale nyanja iyi ya sulfuric acid ku Sicily, ndipo imakopera okha alendo oyendayenda-ochotseratu padziko lonse lapansi.
Chinthu chodabwitsa kwambiri cha chilengedwechi n'chopambana pa dziko lapansili. Nyanja imangopeka ndi kukongola kwake kodabwitsa, kuphatikiza mitundu yosiyanasiyana. M'chilimwe, m'nyengo youma nyanja imalira, koma m'nyengo yozizira imatha kusangalala kwambiri. Zosakaniza mitundu yosiyanasiyana sizidzasiya aliyense wosayanjanitsika. Ndi kovuta kufanizitsa chinthu china chokongola ndi ngozi ndi nyanja ya imfa.
Chifukwa cha kuopsa kwa kuyanjana ndi mvula yowopsya, mipangidwe yapadera ya matabwa ndi mipanda imamangidwira alendo. Ngakhale kuti palibe munthu aliyense wodalirika, podziwa za kuopsa komwe kumakhala kumadera oyandikana nawo, angasokoneze malamulowo ndikubwera pafupi ndi zokongola zokongola, koma ndizoopsa.
Nyanja ya sulfure ili m'dera lalikulu. Ali m'chigawo chakutchedwa Catania, pachilumba cha Sicily ndipo amatchedwa Lago Naftia di Catania.
Ambiri amatsutsa kuti zambiri za chidziwitso cha nyanja ya imfa ndizopeka, zomwe ziribe kanthu ndi zenizeni, koma mungathe kupeza nokha podzichezera nokha.
