Kuyini ukucindezeleka? izinhlobo imicengezi

impumuzo Umhlaba ahlukahlukene kokuvamile. Surface zalo kushintshana ne zigodi ezijulile iziqongo eziphakeme kunazo zonke, afanayo enamadwala ehlangana emathafeni ezibanzi flat. Lesi sihloko sigxile kakhulu omunye izinhlobo impumuzo eliwumhlaba. Kuyini ukucindezeleka? Njengoba kubukeka? Yiziphi izinhlobo imicengezi khona?

Kuyini ukucindezeleka?

Ngo geography, le nkulumo isetshenziswa kaningi. Ikakhulukazi, geomorphology - isayensi etadisha sezwe kule planethi yethu. Ngakho, liyini ukucindezeleka?

Agcwalise e komhlaba nokuma kwezwe ngokuthi i landforms elikhulu ezimbi kulelilizwe noma ulwandle phansi. Ngokuvamile, banalo round ukuma.

On usayizi umcengezi zingase zishintshe kakhulu. Ngokwesibonelo, Afar Triangle eMpumalanga Afrika ihlanganisa indawo enkulu, okulingana amashumi ezinkulungwane amakhilomitha square. Okunye ezinamanzi zinhle nesizotha kakhulu ngobukhulu (njengoba, ngokwesibonelo, Nadbuzhanskaya Basin eNtshonalanga ye-Ukraine).

On imvelaphi yalezi izinhlobo zosizo kukhona zomhlaba, ukuguguleka komhlabathi, glacial, Karst, eolian ngisho mlilo. Ngokusho umbuso amanzi kungenzeka udoti kanye undrained.

Basin atholakala kokubili on zwe futhi on olwandle. Kuyini ukucindezeleka e Oceanography? Lokhu kuveza ukwehla enkulu phansi kolwandle, sizungezwe yezwekazi emthambekeni, umkhumbi-ngwenya emikhulu noma okuvimbezela. I ka ayimigodi kwamanzi ukujula avareji bathambekele idlule uphawu 3500 amamitha.

Lo mgodi ka iChibi iBaikal: umsuka kanye namaqiniso ezithakazelisayo

Eceleni geomorphologists cabangela futhi echibini nezitsha. Lokhu kuncipha ebusweni, wawugcwalisa ngamanzi. ERussia ngobukhulu kanye ezithakazelisayo kakhulu echibini indishi iChibi iBaikal. Kanjani futhi laphuma nini?

Ukutadisha echibini ejulile planethi kuthiwa sina wahlanganyela ekhulwini XVIII. Usosayensi German uPetru uPallas kuqala ukubeka phambili umbono ocatshangelwayo ngemvelaphi ukucindezeleka kwakhe. Ngokusho kwakhe, iBaikal kwamiswa ngenxa yenhlekelele yemvelo yomhlaba wonke. Ngemva uPallas ezizathwini yabo yakhiwe nabanye ososayensi abaningi. Futhi eduze iqiniso wasondela sokuma Soviet VA Hoops.

Eqinisweni, iBaikal Basin iyingxenye enkulu ingxabano zone, uqweqwe ingaphansi okuyinto njalo futhi kakhulu ukufuthelana ngokungavamile. Ngenxa yalokho, i-mass rock kuthiwa zikhubazekile, bona agelezé futhi kwakhiwa uchungechunge emikhulu, manje uzungezwe nxazonke by echibini.

Eqinisweni ezithakazelisayo: Ososayensi banamuhla baye bathola ukuthi ogwini iBaikal ukuhambisa ngaphandle mayelana 2 cm ngonyaka. Ngezikhathi kule ndawo awashintsheki nokuzamazama komhlaba. Konke lokhu kuchaza ukuthi ukwakheka somfula iChibi iBaikal uyaqhubeka kuze kube yilolu suku.

Manje ngoba sewuyazi ukuthi kuyini ukudangala futhi indlela okubukeka ngayo. Leli fomu engakhi impumuzo eliwumhlaba, okungase kwenzeke kokubili ezweni ngaphansi izilwandle nezilwandle.
