The geological process that gave rise to this body structure has also been attributed to crustal downwarping, lug faulting, and mantle plume activity by one study[28] while another theory attributes it to continuous sand deposition and the natural process of sedimentation leading to the governing body of a chain of barrier islands related to rising sea levels.[25] Another theory affirms that the origin and linearity of the Adams bridge may be delinquent to the old shoreline implying that the two landmasses of India and Sri Lanka were once machine-accessible from where coral reefs evolved.
Another study explains the origin the structure due to longshore drifting currents which moved in an anticlockwise direction in the north and clockwise direction in the south of Rameswaram and Talaimannar. The sand was supposedly dumped in a linear pattern along the current shadow zone between Dhanushkodi and Talaimannar with later accumulation of corals over these linear sand bodies.[citation needed] In a diametrically opposing view, another group of geologists propose crustal thinning theory, block faulting and a ridge formed in the region owe to thinning and asserts that development of this ridge augmented the coral harvest-home in the region and in turn coral dwell acted as a `sand trapper.[citation needed]
The tombolo model affirms a ceaseless sediment source and a strong unidirectional or bi-directional (monsoonal) longshore...If you want to get a full essay, order it on our website: Orderessay
