Kungani izihlahla zingakhuli kusuka kumamitha athile ukuphakama?

Wake wakuphawula lokho kusuka ekuphakameni okuthile izihlahla azisakhuli. Uma unenhlanhla futhi uthole nethuba lokuba sezintabeni eziphakeme, uzokwazi ukukuqinisekisa. Kukhona okuthile okuvame ukuheha ukunakwa, izihlahla "zigawulwa" kusuka ekuphakameni okuthile. Kwesinye isikhathi umehluko uyathuthuka, singadweba umugqa wokucabanga ongaphezulu noma omncane wokuthi kunzima kangakanani ukusuka kubo ukuphakama. Ngezinye izikhathi umehluko ucace bha futhi uhlaba umxhwele kangangokuba umugqa oqondile ungathi uvimbela ukuba khona kwezihlahla kuwo. Sengathi kwenzeke okuthile okungazelelwe.

Lesi simo saziwa njengomkhawulo we-arboreal noma umngcele wehlathi ngokuvame kakhulu. Futhi noma ngabe kwamukelwa kabanzi ukuthi kwenzeka ezindaweni eziphakeme zezintaba, iqiniso ukuthi akuyona into ethinta kuphela ukuphakama. Singathola umngcele wehlathi ngokuya ngesifunda somhlaba esikuwo. Futhi yize sizochaza ukuthi kungani, siyabona ukuthi ayithinti izihlahla kuphela, kodwa yonke imvelo jikelele.

Kungani kwenzeka?

Okokuqala, izizathu eziyinhloko ziyimvelo. Isici esifanelekile njengoba usitholile ukuphakama, ngalokho okuhilelekile. Ukusuka lapha, singadiliza izinto ezibhekelekayo:

1. Ithempelesha: Ngokuya ngezinga lokushisa, izimbali zingakhethwa phakathi kohlobo oluthile noma olunye. Esimweni esisithintayo, izinga lokushisa ngokuvamile liphansi kakhulu kangangokuba izihlahla eziningi azikwazi ukuzivumelanisa nalo.
2. Umswakama: Emswakeni ophansi, sinamathafa athe xaxa omile. Ukuphakama komswakama, izitshalo eziningi.
3. Ukwakheka kwenhlabathi
4. Ukuntuleka kwengcindezi emoyeni: khumbula ukuthi phezulu phezulu, ingcindezi iyancipha.
5. Ukwenza kwasendaweni: Emgqeni onezihlahla eziphakeme, sithola ukuphakama okuphansi kaningi lapho sisondela ezigxotsheni. Ngokuphambene nalokho, ukuphakama okuphezulu njengoba sisuka. Isibonelo, iSweden, ese-68ºN, ulayini we-alpine ungamamitha ayi-800 ukusuka. ENorway, ku-61ºN sinayo ku-1.100m. I-Andorra, 42ºN kuma-2.300m. I-Japanese Alps, ngo-39ºN iku-2900. INew Guinea, 6ºS ingu-3.900.

Mayelana nephuzu lesi-5, lokhu kungahluka kakhulu ngokubheka ezinye izinto esizichazile. Kepha ukukunikeza umbono ojwayelekile wokuthi i-latitude ithinta kanjani, ezinye izibonelo zimakiwe. Singaba necala le-tundra ngokwesibonelo, olwandle? Yebo, lapha singayihlola e-Iceland.

Khumbula ukuthi lokhu kuthinta hhayi kuphela ukuphakama, kodwa kucatshangelwa wonke amaphuzu achaziwe. Akuyona into ethile etholakala njalo emhlabeni jikelele ngezimo ezifanayo, kuyinto yomhlaba wonke, futhi ngenxa yalokho inezimo zesifunda ngasinye. Kulokhu, i-Iceland, sinesifunda esinezintaba ezisencane kakhulu, yaqala ukuthuthuka eminyakeni eyizigidi ezingama-20 edlule. Isifunda esinentaba-mlilo kakhulu, sibanda impela, futhi sisondele kakhulu esigxotsheni esisenyakatho.

Ukuphakama nemvelo

Izihlahla, izimbali, izilwane. Ukuphakama kuthinta ngqo konke ngempela. Ngendlela efanayo ebesingalimi ngayo eziqongweni ze-Himalaya, izilwane nazo zithinteka kakhulu ukuphakama.

Ezindaweni eziphakeme kakhulu, sithola indima ehamba phambili yama-invertebrate. Izinambuzane ezinjengezimpukane, amabhungane, izimbungulu, njll., Singazithola emazingeni aphezulu asezintabeni. Ngakolunye uhlangothi, ama-vertebrate alahlekelwa ubukhona. Ngokuya ngokuthi sikuphi, kunjalo, singathola izidalwa ezithile, okuyizinhlobo ezitholakala ezifundeni ezithile, njengezinyamazane ezithile, izinhlobo zezimbuzi noma izimbila, kepha phakathi kwezinto ezijwayeleke kakhulu kungaba yizilwane ezihuquzelayo, njengama-salamanders, izinyoni noma amanye amalulwane. .

Ukuphakama kokuphakama, izimo zokuphila ezimbi kakhulu futhi kunzima kakhulu ukuzivumelanisa. Singacabanga ubusika obunzima, hhayi ukunethezeka okuningi njengoba siseduze nokuphakama okuphansi noma ogwini. Kepha uma uthanda ugqozi oluza nokuthola ukuthula, okugqugquzela umoya ohlanzekile, futhi ngaphezu kwakho konke, ukujabulela ukubukwa kokukhululeka okuhle okusinikezwa yimvelo ... Izintaba eziphakeme ziyiphupho nendawo ekahle, njengoba sekuvele kungenxa yabantu abaningi.
