Muenzaniso: Pasi renyika uye makungwa akaumbwa nekuputika kwemakomo uye kubuda kwemweya. Mvura yemvura kubva kune izvi zvitubu yakasanganiswa mumakungwa, yakawedzerwa nemvura uye chando kubva kune asteroids, protoplanets, uye comets. Mune iyi modhi, "magasi ekupisa" emuchadenga akachengetedza makungwa kubva pakuoma nechando apo Zuva richangobva kuumbwa raive ne70% chete yechiedza charo chazvino. Pakazosvika 3.5 By, magnetic field yePasi yakasimbiswa, iyo yakabatsira kudzivirira mhepo kuti isabviswe nemhepo yezuva. A crust yakaumbwa apo iyo yakanyunguduka yekunze yePasi inotonhorera kuti iite yakasimba. Mhando mbiri dzinotsanangura huwandu hwevhu dzinofungidzira chero kukura kwakasimba kusvika kune yanhasi kana, zvichida, kukura nekukurumidza munhoroondo yepasi nekureba kwenguva refu. Makondinendi akaumbwa nekondinendi tectonics, pakupedzisira yakateverwa nekuenderera mberi kwemvura uye chando kubva kune asteroids, protoplanets, uye makometi.
