Nemihuzuko - ke ... Marine nemihuzuko. Izinhlobo futhi izakhi osogwini olusenyakatho

Indawo lapho kolwandle (noma yimuphi umgwamanda yamanzi) kuyinto ukuthintana ngqo nge eqinile, ngokuthi ogwini. Kulapha kukhona ngxabano njalo yizici ezimbili: amanzi emhlabeni. Ngokuhamba kwesikhathi, ogwini ukuphula ukuthatha indlela entsha ngokuphelele.

Nemihuzuko - a ... Ukunqunywa umsuka wenkulumo ethi

Esikhathini ebanzi umqondo nemihuzuko - inqubo nolokubhujiswa mechanical okuthile. Igama elithi livela egameni lesi Latin abrasio, okuyinto uhumusha njengoba "nokususa" noma "nokususa".

Igama elithi isetshenziswa wesayensi eziningi kanye nezindawo yizenzo zabantu. Ngokwesibonelo, kukhona into ezifana nemihuzuko amazinyo. Le nqubo nemihuzuko okhandlayo izicubu kwamazinyo ngenxa ukuxhumana ngqo ezishelelayo yabo.

Leli gama ingatholakala eyala eziningana ngokwesayensi - komhlaba futhi geomorphology, imithi, ukwelapha izifo zabesifazane Numismatics, njll Ngakho, e-Numismatics nemihuzuko - .. Lokhu bafake metal zemali ngokuhamba imithi yabo. Futhi imithi, ngaphansi kwalesi umqondo ukuqonda ukucasuka odongeni isisu ngenxa umthelela amakhemikhali namandla.

emikhawulweni nemihuzuko - Iyini? izinhlobo osogwini olusenyakatho

Ugu akunakudluliswa iyunifomu, it is njalo singabhujiswa futhi washintsha. Eziyizimbangela zalokhu izinqubo ezimbili: emadlambini namandla adonsela phansi. Ngakolunye uhlangothi, yonke nomdweshu wezwe elisogwini yimuphi amanzi emhlabeni, ngandlela-thile, kwakheka bedle amagagasi okuqhubekayo elakhiwe emanzini efanayo.

nemihuzuko Marine - kuyinqubo nolokubhujiswa yomdabu namadwala okuxekethile ogwini. Kunengqondo ukucabanga ukuthi kuyinto kuncike ezicini ezintathu eziyinhloko:

• Amandla kanye nezinga wave isinyathelo;
• inhlanganiso nokuzinza yamadwala;
• the steepness emthambekeni ugu.

Ngempela, steeper emthambekeni ogwini - bazolokhu liyobhujiswa. Futhi amandla amagagasi ngokwabo, yebo, futhi sithinta zasolwandle nemihuzuko inqubo.

Ngo geomorphology yesimanje ukuhlukanisa izinhlobo eziningana eziyisisekelo yemida:

• Abrasive-denudation (kwakhiwa bedle amagagasi ulwandle kanye emthambekeni izinqubo).
• Fjord (kwakhiwa ngenxa amanzi izikhukhula ulwandle noma ulwandle izigodi glacial).
• Skerries (sakhiwa sebuningini leziqhingi ezincane ezingaba enamadwala ahlukaniswe amavesi ewumngcingo).
• Lima (kwakhiwa ngenxa yezikhukhula kusukela izigaba ulwandle wellhead emfuleni izigodi).
• Riasovye (kwakhiwa ngenxa amanzi asolwandle izikhukhula emfuleni ewumngcingo izigodi ezindaweni entabeni).

Abrasive Beach nesimo sezulu

Kuyini Beach olwalwenza? Futhi libukeka?

Lokho okubizwa ngokuthi i ekhethekile, ifomu ezithile zosizo. Ngamagama alula, kuba impela emaweni futhi ibhange okusezingeni eliphezulu kwesigubhu (kolwandle, ulwandle, ichibi, yokufakelwa amadamu amanzi), okuyinto ahlahlele bedle njalo-surf. Ngenxa yalokho amagagasi njengoba uma uyagudluka umhlaba, "wahlushwa" ngasemanzini kolwandle noma olwandle.

Geomorphologists bakwazi ukubona isakhiwo izici olwalwenza ogwini amane ayinhloko. Ziyakwazi:

• Cliff (eshalofini ugu);
• wave-usike niche;
• Bench - nemihuzuko ngwenya emthambekeni;
• kwamanzi accumulative anesihlabathi ithala hlobo.

Ngo ukwakheka iyiphi coast olwalwenza kuhilela izinqubo amabili aphikisanayo kodwa aphelele. Lokhu nemihuzuko efanele (amagagasi ekubhujisweni ogwini emadwaleni) kanye ekuqongeleleni (ekuqongeleleni imikhiqizo okuxekethile nolokubhujiswa).

Ezingxenyeni ezihlukahlukene zomhlaba ungabona ogwini oluhle kunazo zonke olwalwenza: eNgilandi eScotland, France, iPoland, iRussia USA nase-Australia. Lapha, ngokwesibonelo, ogwini oluseningizimu ye esiqhingini saseSicily kuyinto into eyingqayizivele yemvelo - Scala dei Turchi. Lolwandle yakhiwa idwala sedimentary - Marl. Ngaphansi umthelela eside ngala magagasi emaweni anezinguzunga zamadwala esehlelembe ziphenduka bushelelezi esiteji yemvelo kungamangalisa emhlophe. Njengoba kubukeka, ubona isithombe ngezansi.

Indlela baphule ogwini?

Inqubo obumba ogwini olwalwenza iqala ukwakheka kude amancane ngasesinqeni se emthambekeni yayo. Kancane kancane kwandisa ngobukhulu, abe niche ezinkulu. "Ulimi" idwala kuthé phezu le niche, ekugcineni ehlala futhi yakha onqenqemeni oluncane ugu - eweni.

Coast eweni kungase kuhilele amatshe, isihlabathi, amatshe imfucumfucu emikhulu. Ngezinye izikhathi kuba amafomu kunalokho yinqaba nomumo. Ngakho, ogwini California lingumuzi Mendocino, okuyinto zayo engavamile «Beaches round amatshe» (Ball Bowling Beach) eyaziwa. Surf kancane kancane ubhubhisa kanzima ezinamatshe, okuholela detritus gaya esimweni kolwandle round itshe amabhola. Konke kubukeka kuhle ezithakazelisayo (cm. Photo ngezansi).

Ngokuvamile, ubude ingqikithi ezingwini olwalwenza emhlabeni imayelana ayizinkulungwane 400 amakhilomitha. Ngokwesilinganiso unyaka ngamunye nge amawa futhi Bench amadamu kuthatha cubic metres yizigidi eziyizinkulungwane 10. m impahla detrital.

Ukuvikeleka nemihuzuko

nemihuzuko Marine eletha imizamo amaningi emhlabeni wonke. Ososayensi njalo sizama ukuthuthukisa izindlela eziphumelelayo zokubhekana nayo.

Isivikelo sokumelana nalolu mkhuba kungaba ezemvelo kanye yokufakelwa (man-made). Ngokwesibonelo, ebhishi ukhonza kakhulu ukuzivikela yemvelo ngokumelene imiphumela elimazayo zemihuzuko. Phela, kuthatha babekezelela namagagasi, iyavuleka amandla abo.

Artificial Ukuvikelwa ugu ngokumelene nemihuzuko kuyinto ekwakhiweni ngobuningi imiqulu ngaphakathi ogwini, ukwakhiwa izindonga enamandla ukhonkolo ngasogwini. Siza ukuba sibhekane ngokuphumelelayo inqubo kubhekwe nezindonga ezivimba amanzi. Lokhu izakhiwo zikakhonkolo eside, ezakhiwe at engele unelungelo ugu. Igama lazo uthi konke: odongeni ulwandle lufane "usike 'amagagasi ulwandle, kunciphise amandla kwabo okulimazayo.
