I yezwekazi emthambekeni - ke ... Izici isakhiwo kanye nezinhlobo emthambekeni yezwekazi

Ocean inezigaba eziningana kwesakhiwo. Emthambekeni yezwekazi - lena omunye wabo. Lokho kuyinto uphi? Lokhu uzofunda kusukela kulesi sihloko.

Emthambekeni yezwekazi - kungcono ...

izifundo Geography ezweni hhayi kuphela, kodwa futhi yokuthi itholakala ngaphansi kwamanzi. Ikakhulukazi, ukutadisha sendawo kwamanzi kolwandle ngumuntu isiyalo ekhethekile ngokwesayensi - Oceanography.

Ocean phansi inezingxenye eziningana kwesakhiwo. Emthambekeni yezwekazi - lena esifundeni inguquko phakathi eshalofini engaphezulu, umbhede okuthiwa olwandle, etholakala ezansi. Ngokwesilinganiso, itholakala ekujuleni ezisukela 200 2000 amamitha.

Ngokocwaningo, emthambekeni yezwekazi - ukuqhutshekiselwa okunemibandela bezwe ezwekazini. Le ndlela sezwe kwamanzi kuyahluka emithambekeni kakhulu emaweni, ongafinyelela degrees 30-40. Isikhathi esining impela ke kube nzima elikhulu enamadwala izinyathelo, emihosheni emikhulu namawa. Ngokuvamile zitholakala kwi-yezwekazi emthambekeni futhi kwamanzi kwenhlabathi ukuthi kuzothathwa izinyathelo gravity.

Emthambekeni yezwekazi - lena ingxenye kuqhathaniswa emincane olwandle okuyinto Nokho, u-12% izilwandle zomhlaba.

Izici isakhiwo emthambekeni yezwekazi

Ukuze emithambekeni yezwekazi akuyona nobuntu surface bushelelezi. Ngokuphambene nalokho, isici ngezansi ukukhululeka ezahlukene obukhulu futhi angabacwasi ejulile aphule. Kuvame kakhulu ukubona imihosha ejulile nezigodi. Nge emthambekeni engenhla ngokuvamile sehla uquqaba enkulu idwala, ukwakha fluxes turbid nemisinga.

Emthambekeni yezwekazi ezingxenyeni ezahlukene zomhlaba azifani futhi kuhluke ukujula, ubude emthambekeni. Ngokwesibonelo, ngasogwini Australia ukujula emthambekeni yezwekazi kungenzeka amakhilomitha amahlanu kanye ububanzi 150-200 km. Kodwa eduze emthambekeni zamazwekazi South Africa kuyahluka liphinyiselwe isakhiwo wangenela.

Huge esiteji kwamanzi kanye oceanographers wathola emaphethelweni e-Arctic Ocean. Lapha, kude ngaphansi kwamanzi uya amaChukchi Cap, lapho eseneminyaka Abut emikhulu esinamandla kwamanzi.

Izinhlobo ezinkulu emithambekeni yezwekazi

Ososayensi evamile ihlukaniswe zonke emthambekeni yezwekazi zibe izinhlobo ezintathu zofuzo:

• denudation;
• accumulative;
• denudation-accumulative.

Ngo emithambekeni yezwekazi denudation izinqubo yibona uhlobo rock ekubhujisweni. Kunalokho accumulative, linqobe inqubo ekuqongeleleni impahla umonakalo omkhulu kakhulu. Emthambekeni yezwekazi yalolu hlobo ngokuvamile aqukethe inhlabathi clastic noma isihlabathi. Denudation-accumulative emithambekeni yezwekazi ukumela uhlobo ushintsho phakathi ngenhla embodiments nemithambeka.

Ngokuvamile, i-main "donor" Geological impahla sedimentary nganoma yisiphi emthambekeni yezwekazi kuyinto eshalofini. Rocks sihlanzwe imisinga kwamanzi futhi axazulule ngezansi njengoba izingqimba eqine ezahlukene.
