Umxholo
Inkqubo ye- intlenga Kukuqokelelwa kwezinto eziqinileyo, ezibangelwa ziinkqubo zendalo okanye zovavanyo.
Izinto ezahlukeneyo ukusuka kukhukuliseko lwamatye zingahanjiswa ziiarhente ezahlukeneyo (umoya, amanzi, umkhenkce omkhenkce) ukuya kwindawo apho zibekwe khona. Idiphozithi eqhubekayo yemathiriyeli, ineziphumo zokuqokelelana, okt intlenga.
Inkqubo ye- umxhuzulane Iyangenelela kwiinkqubo zentlenge, kuba ingamandla abangela ukuba izinto, zinqunyanyiswe ngumoya okanye emanzini, ziphinde zibuye.
Nangona kunjalo, amandla omxhuzulane angenelela kunye neminye imikhosi. Inkqubo ye- Umthetho weStokes ubonakalisa ukuba amasuntswana ahlala ngokulula ngakumbi xa edibana nayo nayiphi na kwezi mpawu:
- Ububanzi obukhulu beqhekeza.
- Ubunzima obuphezulu obuphezulu bokuqina xa kuthelekiswa nolwelo olunqunyanyisiweyo.
- I-viscosity esezantsi yolwelo oluphakathi. Oku kuthetha, umzekelo, ukuba isuntswana lobukhulu obufanayo kunye nomxhuzulane othile uya kuhlala ngokukhawuleza emanzini kunase-oyileni.
Intlenga yenzeka xa iarhente ebithuthele izinto iphulukana namandla. Umzekelo, xa umoya uyeka okanye ukuhamba komlambo kuyehla.
Ukuqokelelwa kwezinto ezintsha ekufumaneni kolunye uhlobo kubizwa ngokuba ukwahlulahlula kwaye luhlobo lwentlenga.
Kukho iindawo ezithile kumphezulu womhlaba apho intlenge iqokeleleka khona, ngenxa yeempawu zazo zejografi. Ezi ndawo zibizwa sedimentary eendaba okanye indalo ehleliyo kwaye yahlukile kuyo yonke imimandla ekufuphi, kokubini emzimbeni, kwimichiza nakwimeko yebhayoloji. Imithombo yeendaba ye-sedimentary inokuba yelizwekazi, yotshintsho, okanye elwandle.
Ngaphandle kokuba yi into yendalo, intlenga inokwenziwa iphinde yenziwe kwakhona. Xa yenziwe phantsi kweemeko zelebhu nayo inokubizwa Ukupheliswa, kwaye ibandakanya ukwahlulwa kwamasuntswana anqunyanyisiweyo anobunzima obuthile obuphezulu kunophakathi ulwelo.
Imizekelo yentlenga
- Ukucocwa kwamanzi (intlenga engenziwanga): Isekwe kumthetho ka Stokes, yiyo loo nto kusenziwa iinzame zokunyusa ububanzi bezinto ezime emanzini, uzidibanise. Oku kufezekiswa enkosi ngokugungqa kunye neenkqubo zokuhamba (ezenzeka ngokwendalo egazini kodwa ziveliswe ngamanzi).
- Unyango lwelindle (intlenga engenziwanga): into eqinileyo, organic okanye hayi, emanzini. Inkqubo yentlenge yenza ukuba kuncitshiswe phakathi kwama-40 nama-60% eziqina ezixhonyiweyo.
- Umgibe wesanti (i-sedimentation): Kukho intlenga ebizwa ngokuba yi-discrete okanye i-granular. Oku kuthetha ukuba amasuntswana ahlala njengeyunithi nganye, ngaphandle kokudibana (ngokuchasene nokuqina).
- Alluvium: Intsingiselo yelizwekazi. Izinto eziqinileyo ziyathuthwa kwaye zibekwe ngumjelo wamanzi. Ezi zinto ziqinileyo (ezinokuba sisanti, igrabile, udongwe okanye intlenga), ziqokelelana kwimilambo yemilambo, emathafeni apho kwenzeke khona isikhukula okanye kumanzi olwandle.
- Iindunduma: intlenge yomoya (indalo engqukuva yelizwekazi). Iinduli yingqokelela yesanti ebangelwe sisenzo somoya. Banokufikelela kubude obufikelela kwiimitha ezili-15.
- Iziqithi zeSedimentaryImilambo ihambisa izinto eziqinileyo ezixhonywe emanzini, kodwa ngenxa yokuba zingasoloko zihamba ngesantya esifanayo, eziqinileyo zinokufakwa kwiindawo ezithile, zenze iziqithi. Ziyinxalenye ye-deltas kodwa banokubakho kude nomlomo wemilambo.
- Moraines (intlenge yelizwekazi): I-moraine kukuqokelelwa kwentlenga eyenziwe ngumkhenkce. Kuba uninzi lwamaqhekeza omkhenkce alusekho, ii-moraines zinokufumaneka kwiintlambo ezenziwe ziinguzunga zomkhenkce ezingasekhoyo.
- Iingqaqa ze-Geological (indalo engqongileyo yaselwandle): Ziziingqokelela zezidalwa ezakhiwe ngokudibana kwezinto ezithile eziphilayo nokusingqongileyo. Baxhaswa ngesakhelo. Umzekelo, iingqaqa zekorale kukuqokelelana kweekorale kunye ne-calcareous algae ekhula ngaphezulu komnye nomnye.
- Delta (indawo yodweliso lwenguqu) Xa iziqithi zenziwa yinkqubo yokunyibilikisa, amanzi avula iindlela ezintsha zokuqhubeka nendlela yawo, esenza iingalo kunye nemijelo.
- Amathambeka (indalo esingqongileyo yaselwandle): Zizinto zejografi eziphakathi kwama-200 kunye nama-4000 eemitha ngaphantsi komphakamo wolwandle. Ziye zenziwa kukuqokelelwa kwezinto eziqinileyo ezihanjiswa zivela kumazwekazi, ngenxa yamandla olwandle. Ezi zinto zakha iintlambo, iintaba kunye nemiwonyo. Zihlala zimile kwithafa elithambekileyo, kwiinqwelomoya ezifanayo namanyathelo.
