Amodzi mwa malo odabwitsa kwambiri padziko lapansi ndi Antarctica, mwina chifukwa cha kusakhalapo kwa anthu komanso chifukwa chachilendo komanso zachilendo, mwina zomangidwa ndi anthu nthawi zambiri zimapezedwa zomwe zimanena zakale kosiyana kwambiri ku kontinenti yoyera, zakale zomwe mbiri siinatero. kuganiziridwa.
Mu January 2012, a GeoEye-1 Satellite anajambula malo aakulu, otheka kukhala ochita kupanga m’dziko lachisanu la Antarctica. Poyang'ana koyamba mawonekedwe owoneka bwino a oval amatha kugawidwa ngati zotsalira za nyumba yayikulu kapenanso nyumba yachifumu yakale, monga zomwe zilipo padziko lapansi.
Kodi n'zotheka kuti kutukuka kwakale kunkakhala ku Antarctica pomwe kunalibe madzi oundana? Umboni umati inde n’zotheka. Ndiponso, ngakhale zomera zofolera pansi zakale zapezedwa, kusonyeza kuti zaka mamiliyoni ambiri zapitazo, malo oundana ameneŵa anali ndi nyengo ina, yofunda ndipo anali malo abwino kwambiri okhalamo kaamba ka moyo wa zomera, ngakhale kwa nyama; ndiye bwanji osatero kwa anthu akale?
Nyumba yayikulu ku Antarctica?
Zithunzi za satellite zinavumbulutsa kamangidwe kamene, malinga ndi akatswiri ena, amawoneka ngati nyumba yachifumu yakale, kapena malo ena achitetezo omwe anthu akale otukuka kapena zamoyo zachilendo zomwe zidafika padziko lapansi m'mbuyomu zikadathathawirako.
Zowoneka ngati zowoneka ngati zowoneka bwino zomwe zimapezeka ku Antarctica. Ngongole yazithunzi: Google Maps
Ziyenera kunenedwa kuti ngati ilidi chopangidwa mochita kupanga, izi zingapangitse kuti mbiri yakale ilembedwenso - nkhani yosonyeza akatswiri a mbiri yakale komanso akatswiri ambiri, mosakayikira. Kodi ichi ndi chifukwa chomwe zopezedwa zambiri zodabwitsa (monga izi) sizimaphunziridwa mopitilira ndipo zaiwalika?
Tsoka ilo chifukwa ndi Antarctica, ofufuza odziyimira pawokha omwe amatha kuwulula chowonadi chosasangalatsa kudziko lapansi alibe mwayi wofufuza kupitilira zomwe kompyuta yomwe ili ndi Google Earth imawalola kuchita. Chifukwa chake, timangowona zithunzi za satellite, nthawi zina zosawoneka bwino kapena kusinthidwa pazifukwa zina.
Ndikoyeneranso kumveketsa bwino kuti zomwe zikuwoneka pazithunzizi zitha kukhala ndi zoyambitsa zachilengedwe, mwina zosiyidwa ndi ayezi wosungunuka kapena chifukwa china. Akatswiri ena amakhulupirira kuti ichi ndi chitsanzo chabwino kwambiri cha Sastrugi, pamwamba pa chipale chofewa chomwe chimakhala ndi zolakwika zambiri zapamtunda, zotsatiridwa ndi mapanga akuthwa komanso osakhazikika. Iwo amapangidwa ndi kukokoloka kwa mphepo, ndi saltation wa matalala particles ndi mafunsidwe kwambiri mafunsidwe a chipale chofewa wagwa, onse m'madera polar ndi kozizira.
Ichi sichinthu choyamba chodabwitsa chomwe chimapezeka ku Antarctica (ndipo mwina osati chomaliza). Zambiri mwazinthu zoterezi zapezeka m'zaka makumi angapo zapitazi. Kodi pangakhale chinsinsi, chitukuko chotayika pansi pa ayezi wamuyaya wa Antarctica omwe adalembapo mbiri yakale?
