Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mhepo yakapoteredza pasi nemakungwa zvakaumbwa nokuita kwemakomo anoputika uye kubuda kwemagasi. Mhepo yemvura inobva mumanyuko aya inoungana mumakungwa, ichiwedzerwa nemvura nechando chinobva kumapuraneti maduku, mapurotoplanet, uye makomiti. Mumuenzaniso uyu, "magasi anopisa" ari mumhepo akadzivirira makungwa kuti asaoma nechando apo Zuva rakanga richangobva kuumbwa rakanga richingova ne70% chete yechiedza charo chazvino. Pakazosvika 3.5 By, simba renyika rinobva kumagineti rakanga raumbwa, iro rakabatsira kudzivirira mhepo kuti isaparadzwa nemhepo yezuva. Mienzaniso miviri inotsanangura uwandu hwenyika inopa kukura kwakadzikama kumhando dzemazuva ano kana, zvichida, kukura nokukurumidza pakuvamba munhau yePasi kunoteverwa nenzvimbo yakadzikama yenyika kwenguva refu. Makondinendi akaumbwa neplate tectonics, muitiro pakupedzisira unotungamirirwa nokurasikirwa kunopfuurira kwokupisa kunobva mukati mePasi. Mukati menhambo yamazana amamirioni amakore, makondinendi makuru akaungana ndokupatsanuka. Makore anenge mamiriyoni 750 akapfuura (Mya), imwe yenyika dzakakura zvikuru dzokutanga kuzivikanwa, Rodinia, yakatanga kuparadzana. Makondinendi akazosanganiswazve kuti aumbe Pannotia 600<unk>540 Mya, ipapo pakupedzisira Pangaea, iyo yakaparadzaniswawo 180 Mya. Chimiro chazvino chemazera echando chakatanga makore 40 Mya uye ndokuwedzera mukati mePleistocene anenge 3 Mya. Nharaunda dzakakwirira dzakapfuura nomumativi akadzokororwa echando nokunyunguduka, zvichidzokororwa anenge makore 40 000-100 000 oga oga. Nguva yekupedzisira yegirazi yakazoguma makore 10 000 akapfuura.  Mubvunzo: Ndeipi iri nzvimbo yakakwirira pakupera kwegore umo matunhu anowana glacation uye kunyorova?
