In laylan ee qaaradda geedi socodka denudation intaba nooca burburinta dhagax weyn. lid ku ah accumulative, xukumid habka of raasamaal ee wax dhulka. dhaadhaca qaaradda noocan ah sida caadiga ah waxay ka kooban yihiin korsiiya clastic ama ciid. laylan ee qaaradda Denudation-accumulative wakiil nooca guurka u dhexeeya dalcadaha embodiments kor a.

Guud ahaan, "deeq" wax ugu weyn ee dhulka ku aasan, waayo, mid ka mid ah dhaadhaca continental shelf waa ka. Dhagaxyada leh hadda quuska maydhay iyo hoos u degto sida layers of thicknesses kala duwan.
