Geography. Kodi ndi ku North America wachibale wina

Kodi ndi ku North America wachibale m'mayiko ena, Mzimuyo osati nyengo, komanso anthu, dongosolo la zachuma ndi specialization kapepala lonse la miyalayo. Mayiko m'gawo lake, zinthu zambiri zachilengedwe zimene zili zogwirizana ndi malonda.

Geography ndi nyengo

Africa North America osambitsidwa ndi nyanja atatu: kozizira, Atlantic ndi Pacific. Aliyense wa nyanja awa, yake ndi misa mpweya anapanga pa izo, izo ziyenera kufunika kwakukulu mu nyengo osati m'madera a m'mphepete mwa nyanja, koma mkati m'dzikoli.

Kumtunda, pali mayiko atatu aakulu - Canada, pa US ndi Mexico. Palinso ambiri limati chilumba ndi madera yozungulira ya USA. Canada ndi kwambiri kumpoto mfundo ya dziko si ichi chokha koma Africa lonse. Tikuyankhula zokhudza Cape "Lower". Iwo uli pa Boothia Peninsula ku Canada Arctic. Dzina la Cape ndi unatchedwa wasayansi Mnazareti Lower. Munthu uyu poyamba kufufuza chilumba.

Kodi ndi ku North America wachibale wina, zinachititsa mbiri ya anapeza ake, maonekedwe, kuphunzira ndi chitukuko wotsatira. Lero, pakati pa asayansi munakhala maganizo kuti otulukira Africa anali ana a Viking Group, anachotsedwa tawuni yawo ku Iceland.

Geological Map of North America

Asayansi kugawa Africa patatu Geological dera lalikulu, malire amene kwakukulukulu lifanane ndi malire a mtundu wa mayiko yomwe ili m'malire a Chile.

Woyamba ndi yakale kwambiri m'chigawo geologically lili Canada. Kodi akutchedwa? Izi "Chikopa Canada" ili kumpoto kwambiri m'dzikoli. Iye anamanga zakale nyengo Precambrian, amene anakhudza zosiyanasiyana miyala ya mayiko amenewa. Kodi ndi ku North America wachibale wina, chifukwa, kuphatikizapo, makamaka mapangidwe ake kalelo.

Chifukwa Mbali imeneyi miyala, Canada ndi limodzi mwa mayiko ambiri osiyanasiyana mu mawu chuma mchere. Pa gawo la limati Arctic ndi madipoziti yaikulu ya faifi tambala, golide, kutsogolera molybdenum, ndi, Chofunika kwambiri, ureniamu. A m'madera atangotulukiridwa kumene ku Arctic, ndi madipoziti diamondi kupanga dziko mmodzi wa ogulitsa yaikulu ya zipangizo pa msika lonse.

Chinthu chofunika kwambiri ndi kukhalapo kwa Canada nthaka Sadberiyskogo miyala beseni mu dera la Province cha Ontario, anapanga chifukwa cha wokondwa kugwa kwa miyala yochokera padziko lapansi. Dera limeneli ndi wolemera kwambiri zitsulo ores, amene amalenga anomaly mu madera ozungulira, imene inkatchedwa maginito anomalies Temagami.

Province Geological mu United States ofanana ndi Canada. The kuchotserapo yekha ndi mabacteria anomalous, amatikumbutsa zimaphala kugwa kwa miyala yochokera.

Central America

Kodi ndi ku North America wachibale winayo zosavuta kudziwa ndi kuyang'ana pa mapu. Ngati kuchokera mnansi wake kumadzulo - Europe ndi ku Asia - America ndi wosiyana ndi wachibale yopapatiza kwa Bering Strait, woyandikana kum'mwera, ndi sanasiyane konse, kupatula opangidwa Panama Canal.

limati Central America mulibe mkulu mlingo wa chitukuko zachuma, choncho osatetezeka kwambiri mavuto obwera chifukwa cha masoka achilengedwe amene amayambira ku Caucasus.

Pakati pa masoka ambiri achilengedwe zisonyeze mphepo anapanga pa Atlantic ndi kupita kumadzulo ndi kum'mwera. Pansi zimakhudza awo n'kogwiritsa kugwa limati m'mphepete mwa nyanja US ndi mitundu chilumba cha America Central.

ntchito zivomerezi

The chachiwiri chofunika mbali ya kapangidwe ka Africa ndi chiwerengero chachikulu cha mabacteria seismically yogwira, ndi chifukwa kuti kontinenti kuchitika chivomezi anavutika ndi zikwi za anthu mu mayiko omwe akutukuka ya Caribbean.

The kwambiri kwa chivomezi zonse zimene zinachitika mu United States, anali Wamkulu Alaska Chivomerezi zimene zinachitika mu March 1964. Zinali zoopsa mavuto ake masoka achilengedwe, mavuto amene anapezeka m'dera la makilomita lalikulu zikwi makumi asanu. Zopyola kenaka utentha mamba ndi inatsatana kugumuka ambiri, mudflows ndi kugumuka toyalana misewu phiri ndi kulepheretsa Ndime ya zida asathe malo kumene kunali koyenera.

Komanso, bwanji ndi ku North America, limapereka limati Africa zoonekeratu njira ntchito mu ubale ndi anansi kunja.
