Adam’s Bridge, likewise called Rama’s Bridge or Rama Setu, is a chain of natural limestone shoals, in between Pamban Island, likewise called Rameswaram Island, off the south-eastern coast of Tamil Nadu, India, and Mannar Island, off the north-western coast of Sri Lanka. Geological proof recommends that this bridge is a previous land connection in between India and Sri Lanka.

The function is 48 km (30 mi) long and separates the Gulf of Mannar (southwest) from the Palk Strait (northeast). A few of the areas are dry, and the sea in the location seldom surpasses 1 metre (3 feet) in depth, therefore preventing navigation. When storms deepened the channel, it was supposedly satisfactory on foot till the 15th century. Rameshwaram temple records state that Adam’s Bridge was totally above water level till it broke in a cyclone in 1480.
The ancient Indian Sanskrit impressive Ramayana composed by Valmiki discusses a bridge built by god Rama through his Vanara (ape-men) army to reach Lanka and save his spouse Sita from the Rakshasa king, Ravana. The place of the Lanka of the Ramayana has actually been extensively analyzed as being contemporary Sri Lanka making this stretch of land Nala’s or Rama’s bridge. Analysis of numerous of the older Ramayana variations by scholars for proof of historicity have actually caused the recognition of Lankapura no more south than the Godavari River. These are based upon geographical, botanical, and folkloristic proofs as no historical proof has actually been discovered. Scholars vary on the possible location of the Ramayana however numerous ideas considering that the work of H.D. Sankalia find the Lanka of the impressive someplace in the eastern part of present day Madhya Pradesh.
The western world initially experienced it in Ibn Khordadbeh’s Book of Kingdoms and roadways (c. 850), in which he describes it as Set Bandhai or Bridge of the Sea. Some early Islamic sources describe a mountain in Sri Lanka as Adam’s Peak. The sources explain Adam as crossing from Sri Lanka to India through the bridge after his expulsion from the Garden of Eden, resulting in the name of Adam’s Bridge. Alberuni (c. 1030) was most likely the very first to explain it in such a way. A British cartographer in 1804 prepared the earliest map that calls this location by the name Adam’s bridge.
The Marine and Water Resources Group of the Space Applications Centre (SAC) of the Indian Space Research Organisation (ISRO) concludes that Adam’s Bridge consists of 103 little spot reefs.The SAC research study, based upon satellite remote noticing information however without real field confirmation, discovers the reefs depending on a direct pattern. The function includes the reef crest, sand cays and periodic deep channels. Other research studies otherwise designate the reef as ribbon and atoll reefs.
The geological procedure that generated this structure has actually been associated in one research study to crustal down warping, block faulting, and mantle plume activity. On the other hand, another theory associates it to constant sand deposition and the natural procedure of sedimentation resulting in the development of a chain of barrier islands associated with increasing water level. Another theory verifies the origin and linearity of the bridge to the old coastline from which coastline reef established.
Another research study associates the origin of the structure to longshore wandering currents which relocated an anticlockwise instructions in the north and clockwise instructions in the south of Rameswaram and Talaimannar. The sand might have been discarded in a direct pattern along the present shadow zone in between Dhanushkodi and Talaimannar with the later build-up of corals over these direct sand bodies. In a diametrically opposing view, another group of geologists propose a crustal thinning theory, block faulting and a ridge formed in the area owing to thinning and asserts that advancement of this ridge enhanced the coral development in the location and in turn coral cover functioned as a ‘sand trapper’.
One research study tentatively concludes that there is inadequate proof to show eustatic development which the raised reef in southern India most likely arises from a regional uplift.
