I-steppes yaseMntla-Amerika, okanye yintoni iindonga?

Iinduli zeNxweme Ezinkulu zenyakatho yelizwekazi laseMerika ngaphambi kokuba zenziwe ngamaYurophu zihlala malunga neekhilomitha ezingama-4 000 ubude kunye neekhilomitha ezili-800 ububanzi. Indawo yangaphakathi-ne-continental kunye nokukhusela ukusuka entshona kweeNtaba zaseRoyy zichongiwe ziimpawu zemozulu kunye nezityalo ezincinci. Ngoko yintoni intaba? Ngokuqinisekileyo, eli liyinqanaba. Bafumana igama labo kwiiFrentshi. Intsingiselo yelizwi elithi "iindlovu" liyidla. Ngasemaphandleni bahlala empuma yeZintlambo eziMkhulu, ephakathi nentshonalanga yeKhanada nase-USA. Ngasenyakatho, umda wemihlaba kwihlathi le-coniferous, entshonalanga - kunye neentaba, empuma-kunye ne-steppes ehlathini, kwaye ngasemzantsi bahamba ngokukhawuleza baye kwi-savannah nase-semidesert. Isixa semvula esentsimini yeNorth American steppes sinciphisa kwindlela esempumalanga ukuya entshonalanga. Iindawo ezinomileyo kakhulu zilapha. Ngako oko, izityalo ezitratweni azifani, zitholakala ngamabutho amathathu amaninzi: utshani obude, oxutywe kunye nengca ephantsi.

Ukuncedwa kweentlambo zaseNyakatho Melika

Ziyintoni iindonga zeLwandle oluPhezulu ngokuxhamla? Le ntsimi ihamba kunye neCordillera. Yindawo enobunzulu kunye neendawo ezincinci zeenduli. Enyanisweni, le ndawo ithafeni eliphantsi, okuqhubekayo kwamaNxweme aseNtshona ukusuka empuma ukuya entshona. Izinga eliphakamileyo lalo ndawo liphakathi kweekhilomitha ezili-1.5 ngaphezulu kwinqanaba lolwandle. Imilambo iyahlukana ukuya empuma kwaye ibe yintanjeni yemilambo emibini : eMissouri naseMississippi. Xa le ntsimi yayisezantsi kolwandle lwangaphambili, ukusuka kwidipozithi ebhalwe kuyo. Iimitha zengingqi ziyahlukana ngokwemimandla emine ye-physico-geograal: iindawo ezintathu zendawo-e-Edwards, eMissouri, eLlano-Estacado - kunye nenxalenye ephambili yeentlanzi ezinkulu.

Imozulu

Icandelo elisisiseko semozulu yonke eNyakatho Melika yimilambo yomoya ehambisa umswakama ovela kwiLwandle lwasePacific. Kodwa emanzini amanzi aphantse awa-ahlala phakathi kweeRoyy ne-Cascade Mountains kunye neSierra Nevada. Imimoya eyomileyo ihambela kwiindawo ezihambayo, ngaphandle kokuhlangabezana nezikhawuzo, ngaphandle kokuba umanzi uphuma kwiGulf of Mexico. Ehlobo, ezi ntlanganiso ziphela kwiindudumo nezindwangu, ebusika - ziqhwala ezinkulu. Ngokuqhelekileyo, umoya oqinileyo oqhelekileyo uyabonakala kwiindawo zokutya. Iqondo lokushisa apha lizwekazi -hluke. Ehlobo - umyinge wama-20-25 degrees of heat ebusika - ukuya kwi -25. Kukho amaqabunga kunye no-50 degrees. Empuma, imeko yemozulu iyamanzi - ukuya kuma-600 mm emvula yamanzi iyawa unyaka. Inxalenye yasentshonalanga yomelele, apha iifom zingaphaya kwama-300 mm. Phantse kwiminyaka emihlanu ikhona imililo kwiindlu. Kodwa umlilo ukhawuleza, ngokusemthethweni, ngokukhawuleza, ungalimazi kakhulu umhlaba.

Ihlabathi lezityalo ezinemihlaba

Ziyintoni iindonga ngokubhekiselele kwintlalo yezityalo? Imifuno yemvelo ihlathi kunye ne-steppe. Iyokuqala ibonakaliswa ngotshani-ingca eluhlaza kunye nezikhonkwane ze-aspen kunye ne-birch. Le ndawo itholakala kumda weCanada. Ukongezelela kwezantsi, kwiindawo ze-chernozem, zakha ngokuthe ngqo iindlovu. Kukho i-shrub mfutshane (i-acacia kunye ne-mesquite) kunye nekhava elincinci elingaphantsi. Kwimimandla engaphezulu kwezantsi kukho i-yuccas, i-cacti kunye ne-agaves. Ngaphakathi kwimihlaba kunemihlathi yehlathi. Kumntla - birch. Emazantsi-oki, i-mesquite, i-acacia kunye nomjunipha. Okwangoku, ihlabathi lezityalo litshintsha, kuba umhlaba ovundileyo uphuhliswa ngamafama kwaye rhoqo unkcenkceshelo.

Ihlabathi lezilwanyana zeentlambo

Izilwanyana zasePrairiya zinomdla, kodwa, njengezityalo, azifani kwiindidi. Izihlobo eziqhelekileyo ziyi-squirrels - izinja ze-prairie. Igama labo bafumene ngenxa yezandi ezibethekayo, ezibonisa omnye umqondiso wengozi. Izinja zokudada zihlala kwiikoloni ezinkulu. Bahlala kwimivumba yezokwakha eziyinkimbinkimbi. Imizi ingafumaneka kwindawo engama-5 emitha. Ezi zidalwa zizinto ezidliwayo zendawo: ii-ferrets ezimnyama, i-falcon i-Mexican, i-coyote, i-badgers, i-rattlesnakes kunye neebhokhwe. Ngaphambili, iinkomo ezininzi zezinkumbi zazihlala kwiindawo zokuhlala. Ngesinye isikhathi babesecaleni lokutshatyalaliswa, ngenxa yokuzingela abangenabuhlungu. Ukwangoku, ezi zilwanyana ezinkulu zikhuselwe ngumthetho. I-Coyotes iseninzi kakhulu. Phakathi kweentaka, kukho i-meadow grouse, i- Canadian geese kunye neeseese.

Ukongezwa kweentlambo kwaphakanyiswa ngumlilo kunye neebheji

Indlela yokwazi, mhlawumbi namhlanje akukho mntu unokuba nombuzo malunga nokuba yintoni intlambo, ukuba kwakungengenxa yemililo kunye nenye ibheyi. Iingcali zenzululwazi zikholelwa ukuba kule ndawo ihlathi liyakhula ixesha elide, ngokwemihlaba kunye neemeko zemozulu zendawo. Imililo ye-Elemental, ukutshisa yonke into emhlabathini, kunye neenkomo zezilwanyana ngokutya ngokupheleleyo nokunyathelisa ukukhula okusemncinci zenze into yazo. Izazinzulu zithatha izigqibo zabo, zisekelwe kwiinkqubo ezifanayo e-Afrika, apho izindlovu zinegalelo ekusabalaleni kweentlobo zityalo. Yiyo ke le ndawo yenziwa ngayo ...
