History of zvakawanikwa, kutsvakurudza uye jogirafi pakati North America

In purogiramu chikoro maawa mashoma kuongorora kondinendi yose North America vanotsaura. The nenzvimbo chinzvimbo, nhoroondo yakawanikwa, okunze, kasvisto uye fauna of vari kudzidza zvakadzama. Kuti aivabatsira kugadzirira vadzidzi, takasarudza osimudza zvinhu, izvo zvinogona kumiririrwa munyaya ino.

Muchidimbu pamusoro huru

Saka ngationei kutanga. Chii North America? chidimbu ichi nyika bordered ne nyanza matatu. All ndima yayo iri kuchamhembe hemisphere. Ndicho ichi nzvimbo muna North America iri kukanganiswa zvakananga nezita yacho.

Nyanza washing yakaoma

Sezvo chikazozikamwa, mugumisiro kwemvura mitumbi dzakapoteredza kondinendi, iri zvakakwana guru. Naizvozvo zvakakosha chaizvo kuziva chii nyanza kunyatsobatsira North America. Saka, kubva kumabvazuva kwemhenderekedzo ndiye Atlantic. Akarondedzera Anopatsanura yakaoma pakati Eurasia. Kumhenderekedzo yokumabvazuva pane bays makuru maviri.

On rwokumusoro kondinendi iri bordered ne kweArctic Ocean. Description yokupedzisira Aidavirawo panyaya dzakadai jogirafi (Grade 7). North America, nzvimbo yomugariro chinzvimbo atichandosvika funga zvakadzama munyaya kurutivi rwokumusoro kure ane vakawanda nezvitsuwa uye bays. Greenland chokuita huru. The dzinotaurwa chitsuwa zvikuru kwazvo. Zvinonzi rakamiswa kuchamhembe-kumabvazuva kondinendi, zviri pasi pokudzora dzenzvimbo uye mhepo negurumwandira kweArctic Ocean.

Description of nzvimbo yomugariro North America

Akarondedzera yakaoma iri muna North uye kuWestern Hemisphere. The kondinendi ndokwenguva nharaunda kubva neequator kusvikira muIsthmus Panama kuti kweArctic Ocean pa Cape Murchison. Yokupedzisira ndiyo zvakanyanyisa kuchamhembe pfungwa. Daro pamusoro izvo kondinendi ruoko kubva kurutivi rwezasi kusvikira kurutivi rwokumusoro, riri kupfuura 7000? Km. Panguva kumaodzanyemba ndezvokuti Cape Maryata.

The nenzvimbo chinzvimbo muna North America iri dzinoratidzwa kureba kwete chete kubva neequator kusvika kuchamhembe-kupfuura pfungwa, asi kubva kumavirira kusvikira kumabvazuva. kure Iri vanopfuura zviuru zvina makiromita. Extreme pfungwa: capes St. Charles (East) uye Muchinda Wales (West).

By nyika nharaunda tichifunga yakaoma chitsuwa ndiro yechitatu pakukura. North America wechipiri chete makondinendi maviri - Eurasia uye Africa.

Climate Features

Nokuda chinhambwe chikuru kubva kuchamhembe kusvika kumaodzanyemba, haizi pachitsuwa varipo munenge munyika dzose okunze zvikamu. No Equatorial chete. yacho okunze ari munyoro kunyange kuchamhembe chikamu, sezvo zvose pamwe kumabvazuva kwemhenderekedzo North America okumavirira inodziya Gulf Stream. The chekubuda mhepo inodziya kubva Atlantic anopararira yose kondinendi. Uyewo, hombe aibuda mhepo inodziya makore inoumbwa muGulf of Mexico. Ndokusaka nzvimbo yomugariro North America ine rakananga kukanganisa yomunharaunda ekunze.

Winter nechepakati uye kumaodzanyemba zvikamu nyoro. Kuchamhembe tembiricha inogona inodonha kusvika -36 ° C. Summer uyewo chando, kuti +6 ° C. Kakawanda, kutonhora akadaro kuchengetwa Groenland uye muzvitsuwa yeCanada yezvitsuwa. Kumaodzanyemba yechando kondinendi wacho kudziya. The tembiricha mumwaka ichi harwuwire pazasi 0 ° C. Summers zvinopisa uye mhepo inenge ine unyoro. Kubva kumabvazuva kusvika kumavirira okunze uyewo dzinosiyana zvikuru. Kumhenderekedzo yokumabvazuva masango akawanda, kumavirira uri vainyanya gwenga. Huwandu kunonaya kumabvazuva kazhinji kupfuura kumadokero.

Biota

Nzvimbo yomugariro North America uye ayo ekunze ari kuramba kuumba kasvisto omunharaunda uye miti nemhuka zvakazonaka. Zvinokosha kucherechedza kuti unorema yacho iri munzvimbo dzinodziya mapazi. Nezvenyaya iyi, vakawanda kasvisto aimiririra hardwood uye softwood. In kuchamhembe pane unopinza kuchinja Deciduous musango kweArctic murenje. Greenland uye Canadian Arctic Archipelago vari pasi glaciation.

Kuzivikanwa zviri kunoyerwa kwayo kondinendi mupfumi fauna of. Pano unogona kuwana mhando idzi mhuka kurarama kwete chete munzvimbo vemo, asi muna Eurasia. Vane Vamiririri kuti kurarama bedzi muna North America. Wokutanga mhando rinoratidza kuti izvi zvisati zvaitika muna Eurasia uye North America vakabatana, kureva, vaiva chikamu kondinendi chete. Yechipiri inoratidza kuti kuparadzana makondinendi kwakaitika kare, uye Kushanduka dzichiri wakasununguka negwara.

The napedyo kuna South America

Pedyo North America kondinendi iri South America. Section ichipfuura muIsthmus Panama. Kusvikira pakuvaka Canal zvikepe vaifanira kuenda kumativi South America pamusoro mukomberedzo kuti kubva kuAtlantic kusvika Pacific. Nengano nokutumwa ari gwara oparesheni, dambudziko iri rakanga rapera.

Zvinokosha kucherechedza kuti kosi yechikoro kwekudzidza kwete chete nzvimbo yomugariro North America (giredhi 7th), asi South. Muchidimbu, makondinendi izvi zviviri wakapatsanura neequator. Sezvingatarisirwa, akadaro urongwa kuSouth America kunokanganisa okunze, kasvisto uye miti nemhuka zvakazonaka.

Nhoroondo kudzidza kondinendi

Nhoroondo kudzidza yakaoma zvikuru dzinonakidza. Inogona kukamurwa muzvikamu akawanda. nhoroondo yokutanga yakatanga kusvika XX-XI emakore. Mumakore 981-983.
