Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Mvura ine munyu inofukidza anenge 361,000,000 km2 (139,000,000 sq mi) uye inowanzogoverwa mumakungwa makuru akawanda nemakungwa maduku, negungwa rinofukidza inenge 71% yepasi uye 90% yepasi yepasi. Gungwa rine 97% yemvura yePasi, uye vanodzidza nezvemakungwa vakataura kuti pasi pe5% yeGungwa reNyika yakatsvakurudzwa. Huwandu hwayo hwese hunosvika 1.35 bhiriyoni cubic kilometres (320 miriyoni cu mi) ine avhareji yekudzika kweanosvika 3,700 metres (12,100 ft). Sezvo gungwa repasi rose riri chinhu chikuru cheiyo hydrosphere yePasi, chinhu chakakosha kuhupenyu, chinoumba chikamu chekutenderera kwekabhoni, uye chinokanganisa mamiriro ekunze nemamiriro ekunze. Gungwa reNyika inzvimbo yokugara yemarudzi 230 000 anozivikanwa, asi nemhaka yokuti chikamu chikuru charo hachina kuongororwa, nhamba yemarudzi aripo mugungwa yakakura zvikuru, zvichida anopfuura mamiriyoni maviri. Kwakatangira makungwa epasi pano hakuzivikanwi; makungwa anofungidzirwa kuti akaumbwa muHadean eon uye angave akave anokurudzira kubuda kwehupenyu.  Mubvunzo: Inguva yakadini yePasi iri gungwa?
