Emvelweni kunenqubo yokugqoka okuqhubekayo okwaziwa ngegama lokuguguleka. Lokhu kuguguleka kwenhlabathi kudluliselwa ezindaweni ezahlukahlukene nasezimisweni zemvelo zemvelo. Namuhla sizokhuluma nge Ukuguguleka kolwandle. Kubandakanya ukuguguleka kolwandle kanye nokususwa kwenhlabathi ezintabeni zesihlabathi ezibangelwe yimisinga yolwandle, amagagasi, nemisinga yolwandle.
Kulesi sihloko sizokutshela ngazo zonke izici, izimbangela nemiphumela yokuguguleka kolwandle.
Izici eziyinhloko
Ukuguguleka kolwandle akulutho ngaphandle kokuwohloka okuqhubekayo kobuso bomhlaba obudalwa yimisinga yolwandle, amagagasi nemisinga ehlasela njalo ugu. Amagagasi angenye yezinto ezibonakalayo ezikhukhulayo ezingabonakala. Kodwa-ke, amagagasi nezilwane nakho kudlala indima ebalulekile kule nqubo yokuguguleka komhlaba. Lolu hlobo lokuguguleka lungenzeka nasemadwaleni nasesihlabathini uqobo.
Uma kwenzeka ogwini olunamadwala ambalwa, ukuguguleka kwenhlabathi kubonakala kakhulu futhi kuyashesha. Kumele sikuqonde ukuthi amadwala ayizinto ezinzima kakhulu, ngakho-ke, kunzima kakhulu ukuwohloka ngokuhamba kwesikhathi. Uma okuthile kungenawo lawa matshe, ukuguguleka kwenhlabathi kwenzeka ngendlela eshesha kakhulu. Lapho kunendawo ethambile kunenye endaweni encane, sithola ukwakheka okufana nemithombo, imigudu noma ipula yemvelo.
Kwenzeka kanjani ukuguguleka kolwandle
Sizobona izinyathelo ezinkulu nezimbangela zokuguguleka kolwandle. Izizathu eziyinhloko zokuthi kungani ugu lugqoka njalo ngokuqhubekayo ngenxa yezimo zemvelo: amagagasi nolwandle. Ngakolunye uhlangothi, kuvame ukukhiqizwa isenzo sezidalwa ezithile, yize le nqubo ingabalulekanga kangako ekugugweni kokugcina kwemvelo. Sizohlaziya igxathu negxathu ukuthi yiziphi izici zokuguguleka kolwandle.
Amagagasi
Amagagasi yizinto ezifika ogwini futhi ezingakonakalisa imvelo. Zinezigaba ezimbili zokuhamba. Okokuqala kwenzeka lapho igagasi lakha. Lokhu kusho ukuthi ivukile futhi ishaya ugu lolwandle. Isigaba sesibili yilapho siphenduka isihenqo, okuyilapho sisebenza sengathi yingubo sidonsela yonke intambo olwandle. Le nqubo ikhiqiza umphumela oqhubekayo wokucindezelwa nowokuncipha, nawo odala isici sokudonsa esikwazi ukukhiqiza ukuwa kwamadwala.
Kumele sikhumbule ukuthi ukuguguleka kolwandle kwenzeka ngezinga lesikhathi sokuma komhlaba. Lokhu kusho ukuthi ukuze ugu lugugule ngesenzo segagasi, kufanele kudlule izinkulungwane zeminyaka.
Imisinga ye-Ocean
Kungokunye ukubheka ukuguguleka kolwandle. Indima yawo enkulu ukuhudula. Umsebenzi wegagasi ukhiqiza imisinga engezansi, okuwukunyakaza okuqondane nalokho kwasogwini lwamanje. Imisinga ingakhiqiza ukunyakaza okufanayo lapho amagagasi ehlasela ngendlela engafanele ogwini. Umehluko phakathi kwamaphoyinti aphezulu naphansi wamaza nawo enza imisinga engajwayelekile. La magagasi ancike endaweni esikuyo nonyaka. Ziqine kakhulu uma kunomehluko omkhulu phakathi kwegagasi eliphansi neliphezulu. Yilapho sibona khona amaphuzu okuphuma ngazo zombili izikhathi.
Izinhlobo zokuguguleka kolwandle
Njengoba sishilo ngaphambili, ukuguguleka kolwandle kuncike lapho kwenzeka khona. Ngakho-ke, kunezinhlobo ezahlukahlukene:
- Iziqalo umfutholuketshezi: Zenziwa lapho amagagasi ehlasela izidalwa ezingahlali kahle futhi aziwashe. Izidumbu zikhukhulwa yimifula futhi zivamise ukudla emilonyeni. Ngaphezu kwalokho, ngokuhlukile, bavamise ukusebenza emadwaleni aqhekekile futhi lawa ayabhidlika njengoba amagagasi engena ngamandla futhi acindezela umoya okhona. Yile ndlela, ngokuhamba kwesikhathi, amadwala abhujiswa.
- Ukuhuzuka: Lolu hlobo lokuguguleka kolwandle lwenziwa njengomkhiqizo wokungqubuzana ogwini lwezingcezu zamatshe ezihanjiswa amagagasi namagagasi. Ngokuya ngosayizi nesivinini lapho basuswa khona, bangadala ukuguguleka okungaphezulu noma okuncane. Lolu hlobo lokuguguleka lubalulekile ekwakheni ama-crust abantu abadala, amawa kanye nezinkundla zokuhuzuka.
- Ukugqwala: ukugqwala kwenzeka ngenxa yokuqukethwe kosawoti bamaminerali abakhona olwandle. Le nosawoti bayakwazi ukuncibilikisa izinto eziningi. Ngokuyinhloko bathambekele ekunciphiseni idwala le- limestone elitholakala ngaphakathi. Ngemuva kwalokho ziguqula zibe yimifula yamakhorali noma zisize kwinqubo yokuhuzuka ngezinhlayiya zazo ezincane. Ukugqwala futhi kuvame ukusebenza ngasolwandle. Lokhu kudalwa umusi. Futhi yinkungu leyo nosawoti ofanayo owenza isifaca ezakhiweni ngendlela yokuthuthwa kwamaphethelo ngomswakama.
- Izinqubo zebhayoloji: kungenye indlela yokuguguleka kolwandle, yize kungabalulekanga kangako. Izilwane zibhekele ukuguguleka komhlaba. Ulwandle lunezilwane ezidla amatshe ezaziwa nge-lithophagi. Ezinye yizilwane ezihambisa idwala le-limestone elincibilikisiwe olwandle ukuze zakhe izixhobo zamakhorali. Izimbali nohlaza nakho kunomthelela ekuhlaleni emifantwini yamadwala nokwenza lula ukuthi ziqhekeke.
Izimbangela nemiphumela yokuguguleka kolwandle
Phakathi kwezimbangela zokuguguleka kolwandle sithola okulandelayo:
- Ukuheha kwenyanga: ukukhanga kwenyanga yikho okwenza amagagasi. Ngokwezigaba zenyanga nephuzu lokuhumusha kwasemhlabeni, indlela yokuziphatha kwamagagasi iyahluka.
- Iziphepho: izivunguvungu kunesinye isici esibalulekile okufanele sicatshangelwe. Kunamagagasi anamandla angama-9765 Kg / m1, angakhuphula amandla aphindwe kathathu ngesikhathi semvula enamandla.
Ake sibone manje ukuthi imiphumela injani:
- Amawa: ukuguguleka kolwandle kubonakala ekukhululekeni kolwandle. Amawa yimithambeka enamadwala emi mpo eyakhiwa ukuqhuma kwamagagasi. Ziyimiphumela yokuguguleka kwedwala eliguguliwe.
- Amapulatifomu e-Abrasion: zingamapulatifomu amatshe agugile avela lapho umsinga uphansi. Kuyinto yonke ukunwetshwa kogu.
- Izenzo zasolwandle: Zakha lapho ukuguguleka kolwandle kugcizelela indawo ethile eweni.
- Imigede yasolwandle: Zenzelwe ukulimaza izinto ngobulukhuni obuphansi.
- Inhlonhlo: bayizicucu zomhlaba ezihlanganiswe yi-isthmus.
- Imicibisholo yamaLittoral: akhiwa ngokunqwabelana kwezidalwa.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngokuguguleka kolwandle, izimbangela zalo nemiphumela yako.
