Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Kuyerera kwelava kunomirira imwe nzvimbo huru ine makomo anoputika paIo. Magma inoputika ichibva mumakomba ari pasi pemapatara kana kuti mumapani achibva mumakomba, ichibudisa mafashamo emarara akazara, akafanana neaya anoonekwa paKilauea muHawaii. Mifananidzo yakatorwa nengarava yokudenga inonzi Galileo yakaratidza kuti kuyerera kukuru kwemvura yeLava paIo, kwakadai seaya ari paPrometheus neAmirani, kunokonzerwa nokubuda kwemvura duku yemvura yeLava pamusoro pemvura yekare. Kuputika kukuru kwerabha kwakacherechedzwawo paIo. Somuenzaniso, kumucheto kwokutanga kwokuyerera kwePrometheus kwakafamba makiromita 75 kusvika ku95 pakati peVoyager muna 1979 nokucherechedza kwokutanga kweGalileo muna 1996. Kuputika kukuru muna 1997 kwakabudisa zvinopfuura 3,500 km2 (1,400 sq mi) zvelava itsva uye yakafukidza pasi pePillan Patera iri pedyo. Kuongorora mifananidzo yeVoyager kwakaita kuti masayendisiti atende kuti kuyerera uku kwakanga kwakaumbwa zvikurukuru nemakemikari akasiyana-siyana esarufa yakanyunguduka. Zvisinei, zvidzidzo zvepasi-based infrared uye kuyerwa kubva kuGalileo spacecraft zvinoratidza kuti kuyerera uku kunoumbwa nebasaltic lava ine mafic kune ultramafic compositions. Iyi fungidziro yakavakirwa pakuyera tembiricha ye"nzvimbo dzinopisa" dzeIo, kana kuti nzvimbo dzinopisa, dzinoratidza tembiricha dzinenge 1,300 K uye dzimwe dzakakwirira se1,600 K. Kufungidzira kwekutanga kunoratidza tembiricha yekuputika inosvika 2,000 K kubvira ipapo yakaratidza kuve yakawandisa nekuti mamodheru ekupisa asiri iwo akashandiswa kuenzanisa tembiricha. Kuwanikwa kwemapundu pamakomo anoputika Pele naLoki kwaive chiratidzo chekutanga chekuti Io iri geologically inoshanda. Kazhinji, mapopoma aya anoumbwa apo zvinhu zvinobhururuka zvakadai sesulphur nesulphur dioxide zvinoburitswa mudenga kubva kumakomo anoputika eIo pakumhanya kunosvika 1 km/s (0.62 mi/s), zvichisika makore egasi neguruva akafanana nemambure. Zvimwe zvinhu zvingangowanikwa mumakomo anoputika aya zvinosanganisira sodium, potassium, uye chlorine. Aya mapundu anoratidzika kuva akaumbwa neimwe yenzira mbiri. Mapeji makuru eIo, akadai seaya anobudiswa naPele, anogadzirwa apo sarufa yakanyungudutswa nesarufa...  Mubvunzo: Midziyo inotenderera inoumbwa nei?
sulfur dioxide (sarufa yakasviba)
