Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: The Kelvin<unk>Helmholtz mechanism is an astronomical process that occurs when the surface of a star or a planet cools. Nzira yokufamba nayo: Kelvin<unk>Helmholtz is an astronomical process that occurs when the surface of a star or a planet cools. Kutonhora kwacho kunoita kuti kumanikidza kuderere, uye nyeredzi kana kuti nyika inodzikira somugumisiro. Uku kumanikidza, kunopisawo mwoyo wenyeredzi/wepasi. Nzira iyi inooneka paJupiter neSaturn uye pamapuraneti matsvuku ane tembiricha dzomukati dzisina kukwirira zvakakwana kuti nyukireya ifambirane. Kunofungidzirwa kuti Jupiter anobudisa simba rakawanda kupfurikidza neiyi gadziriro kupfuura iro rinogamuchira kubva kuZuva, asi Saturn angasaita saizvozvo. Maitiro ekupedzisira anoita kuti Jupiter ipfupike nechiyero chemasendimita maviri gore rega rega. Maitiro aya akatangwa naKelvin naHelmholtz mukupera kwezana ramakore rechi19 kuti vatsanangure kwaibva simba reZuva. Pakazosvika pakati pezana remakore rechi19, kuchengetedza simba kwakanga kwagamuchirwa, uye chimwe chinhu chinobva pamutemo uyu wefizikisi ndechokuti Zuva rinofanira kuva nechimwe chinhu chinopa simba kuti rirambe richipenya. Nemhaka yokuti kuita kwezvombo zvenyukireya kwakanga kusingazivikanwi, chinokarakadzwa zvikurusa nokuda kwokutanga kwesimba rezuva chakanga chiri kupfupika kwegiravhiti.  Mubvunzo: Ndeapi mapuraneti maviri anogona kuwanwa pane iyi gadziriro?
Jupiter naSaturn
