Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Kusava nomunda womukati womagineti paVenus kwakashamisa, sezvo wakada kufanana nepasi muhukuru uye waikarirwawo kuva nedynamo mukati mayo. Dynamo inoda zvinhu zvitatu: mvura inoitisa mvura, kutenderera, uye kufambisa mvura. Musimboti wacho unofungidzirwa kuva unotungamirira magetsi uye, kunyange zvazvo kutenderera kwawo kuchiwanzofungidzirwa kuva kunononoka zvikuru, kuenzanisa kunoratidza kuti kwakakwana kugadzira dynamo. Izvi zvinoratidza kuti dynamo yacho iri kushayikwa pamusana pokushayikwa kwokukurukurirana mumwoyo weVenus. Pasi pano, convection inoitika mumvura iri kunze kwepakati pemwoyo nokuti pasi pemvura iri pasi pemvura inopisa zvikuru kupfuura kumusoro kwayo. PaVenus, chiitiko chenyika yose chokumutsiridzazve nzvimbo chingave chakadzivisa maplate tectonics ndokutungamirira kukuderedzwa kwechiyereso chokupisa chinopinda muchikanda. Izvi zvakaita kuti tembiricha yemucheka wacho iwedzere, nokudaro zvichideredza kupisa kunobuda mukati. Somugumisiro, hapana geodynamo yomukati inowanika kuti ityaire munda wemagineti. Panzvimbo pezvo, kupisa kunobva mukati kuri kushandiswa kudziyisazve goko. Imwe bviro ndeyokuti Venus haina musimboti womukati wakasimba, kana kuti musimboti wayo hausi kutonhora, zvokuti rutivi rwose rwakaoma rwomukati rwuri panenge patembiricha imwe cheteyo. Chimwe chinobvira ndechokuti musimboti waro wakatosimba chose chose. Mamiriro ezvinhu omukati anotsamira zvikuru pamwero wesulphur, iyo isingazivikanwi panguva ino. Magnetosphere isina kusimba yakapoteredza Venus inoreva kuti mhepo yezuva iri kudyidzana zvakananga nemhepo yayo yokunze. Pano, ions dzehydrogen neoxygen dziri kugadzirwa nokuparadzaniswa kwemamolecule asina kwaakarerekera kubva mumwaranzi yeultraviolet. Mhepo yezuva inobva yaunza simba rinoita kuti mamwe eaya maion ave nokumhanya kwakakwana kutiza simba rinokwevera zvinhu pasi raVenus. Izvi zvinoguma nokurasikirwa kwehydrogen, helium, uye okisijeni ions, nepo mamorekuru ane uremu hwakakura, akadai sekabhoni dhayokisaidhi, achiramba aripo. Kuparadzwa kwomuchadenga nemhepo yezuva sezvingabvira kwakatungamirira kurasikirwa neakawanda emvura yeVenus mukati memakore mabhiriyoni okutanga pashure pokunge yaumbwa. Kukurwa kwevhu kwakawedzera mwero we...  Mubvunzo: Chii chinopa simba kumayoni kuti asabatwa nomunda wegiravhiti yeVenus?
