The chokhala otsetsereka - izo ... Features dongosolo ndi mitundu ya otsetsereka chokhala

Ocean tichipeza zinthu zosiyanasiyana structural. The otsetsereka chokhala - ichi ndi chimodzi mwa iwo. Chiyani komanso komwe kuli? Izi adzaphunzilanso pa nkhani imeneyi.

The otsetsereka chokhala - ziri ...

maphunziro Geography osati dziko, komanso chakuti ili pansi pa madzi. Makamaka, kuphunzira m'madzi zimachititsa chilumbachi wa nyanja ndi mwambo wapadera sayansi - oceanography.

Ocean pansi idzafotokoza angapo structural. The otsetsereka chokhala - ichi ndi dera kusintha pakati pa alumali inali pamwamba, ndi otchedwa bedi la nyanja, yomwe ili pansi. Nthawi zambiri, lili pa kuya kuyambira 200 meters 2000.

Geologically, ndi chokhala otsetsereka - ndi makonzedwe kupitiriza dziko chokhala. mawonekedwe mtunda m'madzi losiyana otsetsereka kwambiri phompho, amene angafikire madigiri 30-40. Nthawi zambiri ndi kobvuta ndi yaikulu miyala masitepe, maphompho, zitunda ndi ovuta. Nthawi zambiri pa chokhala otsetsereka ndi m'madzi kugumuka kuti zidzachitika mu zochita za yokoka.

The otsetsereka chokhala - uyu ndi gawo ndi yopapatiza ya m'nyanjayo yomwe Komabe, pafupifupi 12% ya nyanja dziko.

Features ya kapangidwe ka otsetsereka chokhala

Pakuti otsetsereka chokhala si khalidwe la yosalala pamwamba. Tikawonetsetsa amafotokozera pansi ndi osiyana wakuda ndi mwachilungamo kwambiri wosweka mpumulo. Sizachilendo kuona zigwembe zakuya ndi zigwa. Ndi otsetsereka chapamwamba zambiri Wopanda misa lalikulu la thanthwe, kupanga fluxes turbid ndi mafunde.

The otsetsereka chokhala mu madera osiyana a dziko sizili zofanana ndi amasiyana kuya, kutalika ndi otsetsereka. Mwachitsanzo, pa gombe la Australia mozama chokhala otsetsereka mwina makilomita asanu ndi m'lifupi 150-200 Km. Koma pafupi otsetsereka chokhala la South Africa yosiyana kutchulidwa dongosolo analowa.

Ikulu m'madzi siteji ndi oceanographers anapeza m'mphepete mwa nyanja ya Arctic. Apa, kutali pansi pa madzi akupita Chukchi kapu, kumene iye anali abut zitunda wamphamvu m'madzi.

The mitundu ikuluikulu ya otsetsereka chokhala

Asayansi conventionally anagawa onse otsetsereka chokhala mu mitundu itatu chibadwa:

• denudation;
• accumulative;
• denudation-accumulative.

Mu otsetsereka chokhala ndi njira denudation amachuluka mtundu wa chiwonongeko thanthwe. Ayi accumulative, kulamulira ndondomeko ya kudzikundikira chuma miyala. The otsetsereka chokhala wa mtundu uwu nthawi zambiri amakhala m'dambo clastic kapena mchenga. Denudation-accumulative chokhala otsetsereka akuimira mtundu kusintha pakati pamwamba embodiments otsetsereka.

Ambiri, waukulu "mwiniwake" Geological nyanja mfundo iliyonse ya otsetsereka chokhala ndi alumali. Miyala osambitsidwa ndi mafunde apansi pamadzi ndi kuthetsa pansipa monga zigawo za thicknesses osiyana.
