Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Yakagadzirwa zvikurukuru nedombo re silicate nesimbi, Io iri pedyo zvikuru nemapuraneti akadai sepasi kupfuura mamwe masatellite ari kunze kweSystem yeZuva, ayo anowanzogadzirwa nomusanganiswa wechando chemvura uye silicates. Io ine density ye 3.5275 g/cm3, iyo yakakwirira yeimwe mwedzi muSolar System; yakakwirira zvikuru kupfuura dzimwe Galilean satellites (Ganymede naCallisto zvikurukuru, vane densities dziri pedyo ne 1.9 g/cm3) uye yakakwirira zvishoma (~5.5%) kupfuura yeMwedzi ye 3.344 g/cm3. Mienzaniso yakavakirwa paVoyager neGalileo kuyerwa kweIo's mass, radius, uye quadrupole gravitational coefficients (nhamba yemitengo ine chokuita nenzira iyo misa inogoverwa mukati mechinhu) inoratidza kuti mukati maro kunosiyaniswa pakati penzvimbo yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa-yakasvibiswa. Musimboti wesimbi waIo unoumba inenge 20% yehuremu hwayo. Zvichienderana nehuwandu hwesarufa iri mumwoyo, nharaunda yepakati iri pakati pe350 ne650 km kana iri simbi, kana pakati pe550 ne900 km kana iri musanganiswa wesimbi nesarufa. Magnetometer yaGalileo yakatadza kuona munda wemagineti womukati paIo, zvichiratidza kuti musimboti hausi convecting. Modeling yeiyo yemukati yeIo inoratidza kuti iyo mantle inoumbwa neinenge 75% yeiyo magnesium-yakapfuma mineral forsterite, uye ine huwandu hwakawanda hwakafanana neiyo yeL-chondrite uye LL-chondrite meteorites, ine yakakwira simbi yezvinhu (zvichienzaniswa nesilicon) kupfuura Mwedzi kana Pasi, asi yakaderera pane Mars. Kuti atsigire kupisa kunoonekwa paIo, 10<unk>20% yechidzitiro chaIo chingave chakanyunguduka, kunyange zvazvo nzvimbo umo kupisa kwakakwirira kwemakomo kwakacherechedzwa kungave kune zvikamu zvakanyunguduka zvakakwirira. Zvisinei, kuongororwazve kwedata reGalileo magnetometer muna 2009 kwakaratidza kuvapo kwenzvimbo yemagineti yakakonzerwa paIo, inoda gungwa remagma makiromita makumi mashanu pasi pevhu. Kumwe kuongorora kwakaitwa muna 2011 kwakaratidza kuti gungwa rakadaro riripo. Ichi chikamu chinofungidzirwa kuva chakakora makiromita 50 uye chinoumba inenge 10% ye...  Mubvunzo: Chikamu chakadini chenyukireya yaLo chinoumba uremu hwacho?
