UMarzi
Iplanethi ebomvu: ibanda, inabuthakathaka, ine-volcano enkulu kunazo zonke kanye nenye yezindawo ezide kakhulu ze-canyons kuhlelo lwelanga.

Isihlabathi esimnyama esibandayo nesivunguvungu esikhulu kanye nomunye wezindawo ezide kakhulu ze-canyons esisimweni sezulu.
IMars ilingana nengxenye ye-diameter yeplanethi. Uthuli lwe-iron oxide lunikeza umbala obomvu. I-carbon dioxide encane yemvelo inesisindo esingaphansi kuka-1% seplanethi.
I-Olympus Mons, ivulcan ephelile, ikhula cishe amakhilomitha angama-22 ngaphezu kwendawo yayo, futhi iValles Marineris canyon system ifinyelela kumakhilomitha ayi-4,000. Imini kaMars ihlala amahora angama-24 namaminithi angu-40, futhi uhlangothi lwayo olujikelezayo (25.2°) lunikeza izimo zesimo sezulu ezifana nezezulu leplanethi. I-Phobos ne-Deimos yinyanga ezincane ezimbili.

Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
