Volcanic matombo kuti vanoumba munyanza paburiro. Pasherufu, kuora mwoyo, guyots

Sezvazvakanyorwa inonzi kuputika matombo kuti vanoumba penyanza paburiro? basalt ichi. Vakafukidza sikweya makiromita anopfuura mazana matatu namakumi matanhatu mamiriyoni, inogarwa mitumbi mvura yedu.

Pose pasi penyanza

The zororo, iro rinoumbwa kuputika matombo kuti vanoumba penyanza pasi, ndiko kunzwisisa uye heterogeneous. Govera zvakananga World seafloor uye pedyo Continental kumahombekombe rakadzika.

Underwater kumucheto inotaura dombo kuputika, chinoumba yomugungwa pasi muchimiro basalt, vane reupenyu chokuita makondinendi pedyo.

Vanodzidza kusiyanisa mapazi pasherefu, Continental materu uye tsoka Continental. Kakawanda zviri vanhuwo nemamiriro pasherufu nzvimbo. Zviri yakabatana munyika. Mushure nhema kuputika matombo kuti vanoumba munyanza paburiro.

sherefu

Kunonyanyisa mvura udzamu ari pasherefu mapazi ose kashoma anopfuura mazana maviri mamita. Kusunungurwa munharaunda pacharo kusiyana dzinza munyoro, pakona rimwe nepfungwa izvo anowedzera zvishoma nezvishoma.

Pamusoro pemvura muenzaniso kukanganisa kare nemafashamo tenuka, coastlines, riverbeds uye reservoirs. Upamhi pasherufu nzvimbo dzakasiyana-siyana. Zvinogona kuva zvakawanda zana metres, uye anogona kusvika makumi makiromita.

The kunonyanyisa upamhi pasherefu mapazi inowira pamhenderekedzo kweArctic Ocean. Narrow pasherefu Anotambanudza pedyo dzeIndian uye Pacific makungwa munharaunda vokuAmerica.

Continental materu

The Continental materu rakanyatsojeka pamawere Musara kuti anogona kuenda pakadzika pachiyero makubhiti zviuru zvitatu. rutsoka Continental afanane pachena, kuva asiri yunifomu undulating penyika.

Noupamhi chikamu ichi penyanza pasi kusvika mazana makiromita, asi kudzama iri achingopiwa makiromita matatu chete. Kana pamubhedha, zvinonzi mudungwe zvinenge zvakakwana kuputika matombo kuti zvinoumba pasi mumakungwa uye makungwa. It ane kunzwisisa Morphology. On kwayo pamusoro, pane anooneka zvikuru nemichinjiziri uye heaths, kuputika kwemakomo, zviwi yose neeSultan gomo.

kuhondo

Dzimwe nguva, pane pemvura pazasi munoyerera mvura yetsvina. kunonyanyisa udzamu yavo matanhatu makiromita. Kakawanda, zviri vakaronga akaererana hurukuro yacho makondinendi kana kudzokororwa Bends makondinendi. Nhamba huru zvimwiro akadai pfungwa pazasi nePacific Ocean.

shamisa guyots

Guyot - chimwe chinhu penyanza paburiro. Guyots vari kuputika zvakasikwa uye vari sandara pagomo, chirefu kupfuura pasi mumapani.

Pane imwe nguva, miganhu dzakadaro dziri pamusoro mvura pamwero, asi akabva akaenda pasi. Just pamusoro pemvura penyanza pasi, kune vanopfuura zviuru zvine gumi dzakasiyana-siyana nenhongonya ose kuputika mavambo gomo.
