Iphasi (iplanethi)

Iphasi liplanethi yesithathu ukusuka eLangeni begodu yiyo kwaphela into yeenkwekwezi eyaziwako bona inepilo. Lokhu kwenziwa kukuthi iPhasi liyiphasi elilwandle, elilodwa ehlelweni lelanga eliphethe amanzi angaphezulu kwamanzi. Pheze woke amanzi wephasi aselwandle lwawo, amboza ama-70.8% we-Earth's crust. I-29.2% eseleko ye-Earth crust yindawo, inengi layo itholakala ngendlela yamazwekazi ngaphakathi kwe-hemisphere yephasi. Inengi lephasi lephasi linomswakama begodu limbozwe ziintjalo, ngesikhathi amashidi amakhulu weqhwa eenkangala ze-polar zephasi agcina amanzi amanengi ukudlula amanzi wephasi, amachibi, imilambo namanzi womkhathi ahlanganisiwe. I-crust yephasi inamapuleti we-tectonic akhamba kabuthaka, ahlangana ukukhiqiza iintaba, iintaba-mlilo, nokusikinyeka kwephasi. Iphasi linomgogodla wangaphandle owuketshezi okhiqiza i-magnetosphere ekwazi ukuphambukisa imimoya eminengi yelanga ebhubhisako nemisebe ye-cosmic.
