Geography. Njani na ilizwekazi North America xa kuthelekiswa kwabanye

Njani na ilizwekazi North America xa kuthelekiswa nezinye amazwekazi, eyikhethayo kuphela imozulu, kodwa labemi, isakhiwo kwezoqoqosho kunye ekuthatheni izifundo njengeziphambili nokwabiwa ehlabathini lonke ekrwada. Amazwe e nommandla wayo, izityebi hlobo ngeziveliso zendalo ezifanelekileyo urhwebo lwamazwe ngamazwe.

Geography ne sezulu

Ilizwekazi North America zihlanjwe iilwandle amathathu: i-Arctic, Atlantic kunye Pacific. Nganye kwezi elwandle, kambe ke khona umoya akhiwa phezu kwawo, abe yayibaluleke kakhulu kwimozulu nje kuphela kwiindawo ezingaselunxwemeni, kodwa ngaphakathi kweli lizwekazi.

Kwi nemisinga, kukho amazwe amathathu ezinkulu - Canada, i-US kunye Mexico. Kukho kwakhona inani elikhulu siqithi ithi kunye nakwimimandla obesondliwa USA. ECanada kwinqanaba osemantla hayi nje eli lizwe kodwa lonke eli lizwekazi. Sithetha i-Cape "Murchison". It is on the Boothia Peninsula Canadian Arctic. Igama ekapa yathiywa emva sisazinzulu Rene Murchison. Lo mntu wokuqala walukhenketha lo zwe.

yindlela ilizwekazi North America kuthelekiswa nabanye, kwakhokelela imbali ukufunyanwa yayo, inkcazelo, ukufunda kunye nophuhliso elandelayo. Namhlanje, phakathi izazinzulu anamathela uluvo lokuba discoverers belizwekazi kwinzala ka-Viking Group, bagxothwa zokuhlala kwabo Iceland.

Geological Map of North America

Izazinzulu uwahlule kwilizwekazi ibe kummandla ezintathu eziphambili zejoloji, imida kakhulu ungqamane kwimida yesizwe yamazwe akhiwe kwi kummandla yezwe.

Iphondo ngokwakheka yokuqala neyona yamandulo ibekwe eKhanada. Yintoni kubizwa? Oku "Shield waseKhanada", ibekwe ngasentla egqithiseleyo kwilizwekazi. Yena kwakhiwa ngexesha lamandulo Precambrian, nokwadala ukwahluka wejoloji kula mazwe. Njani na ilizwekazi North America kuthelekiswa nabanye, ngenxa, kuquka, kwaye ingakumbi lasungulwa kumaxesha amandulo.

Ngenxa kule inkalo nokwakheka, Canada lelinye lamazwe abaninzi abohlukeneyo ngokwemiqathango ekuphononongeni izimbiwa. Ngomhla kummandla ithi Arctic iidipozithi ezininzi nickel, igolide, ilothe, molybdenum, yaye, okona kubaluleke kakhulu, uranium. A imimandla esanda yafunyanwa kwi-Arctic, i-iidiphozithi diamond kwenza ilizwe omnye kubathengisi inkulu of raw materials kwimarike yamazwe ngamazwe.

Inkalo ebalulekileyo ubukho komhlaba waseKhanada Sadberiyskogo ekrwada isitya kuloo mmandla kwiPhondo Ontario, kwakheka ngenxa impembelelo esibhakabhakeni kumphezulu Yomhlaba. Lo mmandla esisityebi kunene sisimbiwa yesinyithi, kwaye lidala anomaly kwindawo ezingqongileyo, leyo kuthiwa mgaqweni magnetic Temagami.

KwiPhondo Geological eUnited States ezifana waseKhanada. Ezi nketho kuphela imimandla anomalous, sifunda yimingxuma zimpahla.

Central America

Njani na ilizwekazi North America xa kuthelekiswa omnye lula ukufumanisa ngokujonga kwi imephu. Ukuba kummelwane wayo asentshona - Eurasia - Melika siyahlukana isizalwane elimxinwa ukuba ukukhumbula Strait, ummelwane ukusuka emazantsi, oko abazahluli konke konke, ngaphandle umntu-ezenziwe ePanama Canal.

ithi Central American abanayo inqanaba eliphezulu yophuhliso loqoqosho, yaye ngoko banokuziva bengakhuselekanga kakhulu imiphumela emibi ziintlekele zendalo kaninzi zenzeka kulo mmandla.

Phakathi iintlekele zixhaphakileyo zendalo kufuneka ibonise iinkanyamba benziwa phezu Atlantic kwaye ihamba ukuya entshona kunye nomzantsi. Phantsi impembelelo yazo ekugqibeleni uya kuwa US States lonxweme kunye neentlanga kwisiqithi Central America.

ziintshukumo zenyikima

Eyona yesibini obalulekileyo isakhiwo zwekazi inani elikhulu lwemimandla seismically esebenzayo, kangangokuba kwilizwekazi kwenzeka inyikima enkulu efunyenwe amawaka abantu kumazwe asakhasayo zeCaribbean.

Okubaluleke kakhulu yonke yenyikima ezenzeka eUnited States, Oyingcwele Enkulu yaseAlaska eyenzeka ngoMatshi 1964. Kwaba ezinkulu imiphumela yayo iintlekele zemvelo, imiphumo apho waziva kwindawo kweekhilomitha amawaka mahlanu square. Nje ngaphaya iingcangcazela balandelwa landslides ezininzi, mudflows kunye landslides, idlulela iindlela intaba Wanciphisa isicatshulwa kwezixhobo yokuhlangula ukuya kwiindawo apho ke kuyimfuneko njalo.

Kwakhona, njani na ilizwekazi North America, oko kunika States kwilizwekazi sethubeni ezicaceleyo ulwalamano kunye nabamelwane aphesheya.
