Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Kufanana nePasi, Mars yakatosiyana kuva musimboti wesimbi wakakora wakafukidzwa nezvinhu zvisinganyanyi kusimba. Mienzaniso yazvino yemukati mayo inoreva musimboti une nharaunda yemakiromita 1,794 ± 65 (1,115 ± 40 mi), inoumbwa zvakanyanya nesimbi uye nickel ine anenge 16<unk>17% sarufa. Iyi simbi ((II) sulfide musimboti inofungidzirwa kuva yakapetwa kaviri muzvinhu zvakareruka kupfuura zvePasi. Musimboti wacho wakakomberedzwa nomupendero wesirivheri wakaumba zvinhu zvakawanda zvomunyika uye zvinoputika papasi, asi unoratidzika kuva usina basa. Kunze kwesilisium neoksijeni, zvinhu zvakawanda zvikuru zviri muchikanda cheMars isimbi, magnesium, aruminiyamu, calcium, uye potassium. Ukobvu hwepakati hweguru iri hunenge makiromita makumi mashanu (31 mi), nehukobvu hwepamusoro hwe 125 km (78 mi). Ganda renyika rinenge rakareba makiromita 40.  Mubvunzo: Musimboti wacho wakapoteredzwa nomucheka worudzii?
