Izindawo zemvelo eNyakatho Melika: izici Ukucaciswa

izindawo zemvelo eNyakatho Melika ukudonsa eduze meridians, ngoba endaweni yaleli zwekazi ngamunye unethuba ukuthuthukisa ezimbonini ezithile. I ajulile endaweni yemvelo, kulapho-ke sisalokhu eduze Meridian. Iqiniso lokuthi phambili sendawo yezinguquko isilinganiso ukushisa kanye umswakama hhayi kuphela ukusuka enyakatho kuya eningizimu, kodwa futhi usuke entshonalanga uye empumalanga.

izindawo zemvelo enkulu yeNyakatho Melika, etholakala endaweni Greenland kanye Canadian Archipelago, ngokuthi Arctic ezingwadule. Njengoba izimo zezulu abanokhahlo kakhulu, lokhu kwaba nomthelela ukumelwa ompofu kakhulu yezimila nezilwane ezihlukahlukene. Kulezi zindawo ezingenziwanga elalihlala ice, kungabonwa kuphela wona kanye ulele. Cishe lesi silwane umhlaba wonke uhlala phansi olwandle.

Esikhathini kude lé enyakatho zwekazi likhulu zone nezimfunda. Njengoba okumelwe kwenziwe kuhlale nomswakama, insimu phathelana amanzi. Cishe yonke indawo embozwe wona kanye ulele. Kepha emithini, birch yemifino kanye Alder awufikeleli ukuphakama ezingaphezu kuka-5 cm.

Lapho ziqhubeka eningizimu, izindawo zemvelo eNyakatho Melika ubukeka emathafeni ngokuya. It kubhekwa isigaba zesikhashana futhi esibonakala ngokuqina kushintshana amahlathi nezimfunda izindawo. ibuye libhekene khona Alder futhi willow zamahlathi. Kuphela endaweni emifula ziqala ukuvela sonwele futhi larch.

endaweni yemvelo ihlathi lezihlahla itholakala eningizimu olwengeziwe. Lapha ungakwazi ukubukela ebusika nokhahlo futhi eside futhi ehlobo - emfushane futhi efudumele. Ngokuphathelene inhlabathi umswakama nomoya, kusukela endaweni libhekene nenkinga yezinga eliphansi ukuhwamuka kanye nomswakama lapha ngokweqile.

Izinto, North amaMelika libhekene izigaba eziphakathi. Ngakho, phakathi coniferous futhi amahlathi lezihlahla ndawo yamahlathi okuxubile.

Futhi kakade endaweni endaweni Appalachian emelelwa amahlathi broadleaf, esibonakala by ezihlukahlukene zemithi. Njengoba lezo zinkomo, kukhona izinyamazane eziningi, izingungumbane, uthela baribalu futhi opossum, okuyizo kuphela abameleli marsupial e lonke izwekazi.

Kepha izindawo flat kuleli zwekazi, kukhona indawo ehlathini-asemaqeleni. Eastern ingxenye libizwa enkangala, ngoba degree ephakeme umswakama. Namuhla, le ndawo tilled ngokugcwele ngoba libhekene ukulingana zenhlabathi, izimo ezikahle zezulu emhlabathini omuhle omnyama.

ENyakatho Melika, lapho izindawo zemvelo zitholakala kahle endaweni ethile indawo, libhekene khona zone asemaqeleni abahlala engxenyeni ephakathi ye zwekazi. Lapha, semali ukushisa ihlinzekwa, kodwa lokhu akuwona isamba ezanele umswakama inxephezelwa.

Ngokuqondene ingxenye esempumalanga yalesi zone nakwezifudumele, lapho ukhule amahlathi okuxubile, emelelwa izinhlobo eziningi of AmaConifers, izihlahla zesundu yemifino kanye izihlahlana zezintaka siluhlaza oki.

Uma sikhuluma coast Pacific, ubuswa amahlathi oluqinile futhi ezihlabayo. Nenhlabathi kukhona ensundu, zikhula eziningi zezinyoni ezingavamile siluhlaza oki, okuyinto ayesevele aziwa phambi Ice Age.

izindawo zemvelo of America, bangazihluphi enhlonhlweni eFlorida naseCalifornia iye abizwa ngokuthi nakwezifudumele futhi ezishisayo. I esishintshashintshayo kuthiwa alternated nezinye Meridian ngamunye. Ingxenye kwangaphakathi ugajwe ngokugcwele ezindaweni savannah kanye ehlathini. Ngokuphathelene Atlantic elisogwini, it is ngobuningi oswakanyiswe imimoya ukuhweba, ngoba eziningi kakhulu emahlathini asezindaweni ezishisayo.

Esikhathini Cordillera ngokucacile kakhulu emelelwa eziphakeme zone.
