Lawrence umshushuluzo (572 m) - Isilinganiso kwale ngxenye kubanga eliphakathi 400-500 m esiphezulu ukujula Bay ukujula.

Amanzi usawoti kanye lokushisa

imisinga amabili Gulf (elaseGaspé futhi Cabot) yakha kwegazi cyclonic, ezihambayo nokuhamba kwewashi. Amanzi olwandle has imikhakha emithathu, okuyizinto ezahlukene lokushisa kanye usawoti. Phezulu edlulayo kakhulu. Ngezinye kokuhlukana yayo ezithinta izimo zezulu.

Amazinga amanzi lapha zokhahlamba kusuka +2 ° C kuya +20 ° C. Kusukela ngoDisemba kuya March ungqimba ebusweni kungenzeka embozwe iqhwa futhi akhiwa zeqhwa. I ukujiya ungqimba 18 m - ehlobo 54 m - ebusika. Usawoti - 32-34 ‰. Amanzi isigaba sesibili sihamba ngesikhathi ka 50-100 m lokushisa ukujula -. Mayelana 0 ° C, usawoti kancane encishisiwe - kuze kufinyelele 30-32 ‰. Isendlalelo engezansi amanzi kokuba lokushisa mayelana +5 ° C futhi usawoti okusezingeni eliphezulu - ezingaphezu kuka-35 ‰. Warm amanzi ungqimba aphansi sihlinzekela Labrador, zihambisana bay sangaleso encane.

sphere geological

St Lawrence River wageza kwi phansi bay isiteshi emaphakathi. Ufika imingcele empumalanga. Ngenxa ukugeleza enkulu amanzi omfula olwandle amashumi eminyaka kakhulu savela biota kwesigubhu.

Futhi eningizimu umkhawulo bay Appalachian Izintaba emelelwa rocks enamadwala, kwakheka Paleozoic aphansi. Phansi eningizimu Gulf of St. Lawrence ethulwa granites Devonian futhi inhlabathi sikhubazekile yamadwala mlilo. Futhi, kukhona amabala yamadwala sedimentary kwesikhathi Carboniferous, le Triassic futhi Permian. namaminerali sedimentary e phansi bay khona.

umkhombe Deep emanzini abonisa ukuthi phansi ubumbe ngaphansi kwethonya Ice Age. Eside ingcindezi ice lwajula phansi bay. Iqiniso lokuthi le ndawo echayeke zamaqhwa, iqiniso lokuthi amanzi kwi freezer minyaka yonke kusukela ngo-January kuya ku-March-April.

Isimo sezulu

Kulesi simo samanje umzimba ngamanzi njengoba Lawrence Bay emzini Lawrence, Arctic, has a uhlamvu monsoonal. air lokushisa phakathi kunqoba +15 ° C futhi akuvamile lehla angaphansi kuka -10 ° C Inyanga enomoya konyaka - ngo-February, ezishisayo - Agasti. Ngenxa yesimo sezulu yezimvula ebusika ziya uthule imimoya enyakatho-ntshonalanga, ngokuletha abandayo, futhi ehlobo - eningizimu-ntshonalanga, yokumatisa nokushisa kanye nomswakama eliphezulu.

umsebenzi zokuzamazama komhlaba

Appalachian uhlelo entabeni nazo zaba neqhaza izici zokuzamazama komhlaba esifundeni. Ukuma kwendawo yendlela phansi Gulf wehlukile kweminye imizimba amanzi onqenqemeni empumalanga lweNyakatho Melika. 45 km - ezifana ukujiya ipharamitha has Gulf of St. Lawrence.

Indawo into ithinta kakhulu umsebenzi wayo. uqweqwe eMhlabeni yakhiwa izingqimba ehlanganisa amagagasi longitudinal kwesikhathi Carboniferous. rocks denser amanga ezingqimbeni aphansi kanye engenhla ethulwa rocks carboxylic. Lokhu kusikisela ukuthi esikhathini esidlule kule ndawo kwaba ukugadlwa ukuzamazama komhlaba esebenzayo, kodwa okwamanje lo msebenzi liphelile. Nakuba, ngokusho kwemiphumela yocwaningo endaweni yonke iNhlonhlo YaseGaspé ngezikhathi wazizwa okusezingeni eliphezulu longitudinal wave isivinini (mayelana 8.5 km / s).

wemikhumbi

Okwamanje, kukhona iGulf of St Lawrence - yindawo lapho navigation ethuthuka ngenkuthalo. A eshalofini zone efanelekayo okudoba ngenjongo yezentengiselwano. Lezi zilwane ezivamile Gulf: haddock, i-halibut, ulwe, ulwandle bass, inhlanzi. Futhi, amasimu uwoyela athuthukiswe sogu lolwandle.
