Tropical shacaab jasiiradda - formation iyo hannaanka deegaameed

In miyir caadiga ah ee jasiiradda - waa meel ka mid ah dalka, hareereysan biyaha on dhinacyada oo dhan. Ereygan waxaa loola jeedaa goobaha sida weyn ee dalka, tusaale ahaan, Iceland, iyo meeshii bannaanayd haraaga yar oo meel on webiga, taas oo si buuxda u baaba'aan karaa daadka. By jasiiradaha asal ahaan ay noqon kartaa dhulweynaha (abuuray by dhaqdhaqaaqa taarikada tectonic), Kobenhagen (timi sabab u tahay qarax ee marno) namytye (salaysan bacaadka ah, kuwaasi oo ay soo sameeyey xarig koob ah), macmal ah oo ugu dambeyntii qarsan Jasiirada Maldives dheeraad ah. Haddii afar kooxood ugu horeysay, waxaa iska cad in ay ahaayeen natiijada geedi socodka tectonic dabiiciga ah ama hawl aadanaha, waxa ku lug leh dhismaha jasiirada Maldives, maxaa yeelay, waxaynu og nahay in shacaab ah - shaqeeyo nool?

In biyaha diiran badaha kulaylaha, kuwaas oo abuuray oo heer hoose la yaab leh in ay ku quudiyaan on plankton degi doonaan, qabtay gacmahaaga ay. xayawaan kasta sida dhistaa inuu nafsaddiisa koob nuuradda. Buro danbeyn dhinto iyo koobka weli. Iyagoo ka duulaya ay buro cusub dhistaa laftiisa deggan nuuradda. Iyo deegaanada shacaab koraan, guuxa ilaa plankton qorraxda ilaa ay ka gaaraan heer badda kamana soo sara kici doonaa dalka korkiisana waxay. Tani foomamka jasiirad shacaab.

Waa wax caadi ah in loo qaato in this - jasiiradaha yar yahay, sida shacaab ah - xayawaanka badda, oo waxay u dhimanayaan on dhulka. qoto dheer The fiicnayn iyaga u - oo ku saabsan 30-10 mitir, halkaas oo aan la dareemay dabeylo iyo iftiinka qoraxda la mid waqti ku filan oo ay. Waa maxay sababta, ka dibna, nolosha dhabta ah, oo ah jasiirad shacaab gaari karaan height a dhowr boqol oo mitir? Haa, maxaa yeelay, taargooyinka tectonic si joogto ah u dhaqaaqin dhulka. Degidda heerka talona kasoo kicin laga yaabaa in a jabalo shacaab ama ku rid boqortooyada gudcur weligeed ah, at 200-300 mitir. Waxaa cad in muddo jasiiradda falna sanyahay waxaa daboolay ciidda iyo daaqsinka, laakiin weli ku saleeyaan waxa ay ka koobnaan doonaa Qalfoofkii nuuradda xad-dhaaf ah polyps muddo dheer dhintay.

Coral Island noqon kartaa laba nooc: jasiiradda dhabta ah, isagoo la yaqaan noo nooca quruxsan sareeya heerka biyaha badda ee foomka of dhagaxyada, iyo atoll ah. Waa maxay fadhiyaa bed iyo sida ay u qabanqaabiyey? Pretty fudud, inkastoo muddo dheer. Bed gaadhaya tahay mid aad u badan ee Badweynta Pacific, halkaas oo, sida aad ogtahay, waa hawl Kobenhagen aad u xoog badan. Bal qiyaas jasiirad, kaas oo la Qolol ku xusan bohol volcano biyaha. At salkeeda, biyaha, ma kululaynta oo kaliya by qorraxda, laakiin sidoo kale magma karkaraya meelo hul dheer, waxay jecel yihiin inay degaan polyps. Way dhisi Qoryaale agagaarka jasiiradda, waxaa belting sida giraan ah. Markaas, ka dib markii qarnigii a dhaqdhaqaaqa shacaab, qarax Kobenhagen dhacdaa oo buurta ... qarxay baaba'aa in biyaha moolka dheer. Laakiin shacaab yihiin! Iyada oo atoll diyaarad u muuqda hareereeyeen by giraan ah badda buluug, gudaha of taas oo haro badda cagaaran - intii ka hadhay oo volcano mar ahan jirtay oo dhan.

Dabcan, mar walba ma volcano ka quustay badda ku tuuraya, iyo gasiiradaha Kobenhagen iyo shacaab ugu badan. Tusaale ahaan of this aan ku aragno gobolka Tonga khaasatan bio magmatic-(Polynesia), taas oo ah kooxdu ka mid ah jasiiradaha Kobenhagen hareereysan Qoryaale dhagax badeed, iyo bed gaadhaya. Tusaale A classical of atoll isagoo qaab giraanta ku dhowaad idelno waa Jeexitaanka.

Coral Island - ecosystem adag. Waxaa la odhan karaa in Qoryaale ah kuwa ugu tiro badan ee dhammaan degaanada badda. Marna ha ka hooseeya 20 darajo heer-kulka biyaha, hoyga ah ee laga heli karo ee shacaab waddooyinka, boholaha iyo duurka u dhaco, tiro badan oo cunto ah soo jiidan kala duwan oo xayawaan. Burooyinka baabbi'in plankton, oo ay, markeeda, ruugi midabo kalluunka baqbaqaaq, kalluunka balanbaalis, iyo sidoo kale kalluun "taaj ayay qodxan" ayuu voracious. koriya Reef degaan urchins badda , iyo anemones badda. The ku nasanayay Jannooyin shacaab amfipriony magan yar ina ogeysiiyey by cartoon ah "kalluunka Nemo", iyo in godadka ku shacaab dhintay sugi ål ugaadha ay. Nasiib darro, ay sabab u tahay waxqabad shacaab aadanaha dulmiga waa sii yar, maxaa yeelay, polyps ay ku nool yihiin oo kaliya in biyo aad u nadiif ah. Xitaa taabashada shacaab ah waxay keeni kartaa in uu dhintay. Sidaa darteed, sida wadamada kulaylaha, marnaba talaabo on polyps ah, iyo xataa more hana burinina laamaha shacaab jilicsan.
