Adam's Bridge, also known as Rama Setu, is primarily composed of a chain of limestone shoals.
Geological Composition
Geological evidence indicates that Adam's Bridge, a natural feature that once formed a land connection between India and Sri Lanka, is fundamentally made up of a series of limestone shoals. These shoals are natural, submerged elevations of the seafloor, predominantly consisting of limestone materials.
Structure and Environment
The limestone shoals of Adam's Bridge are situated within a remarkably shallow sea, where the water depth typically ranges from one to ten meters. This shallow marine environment has contributed to its historical recognition as a natural causeway, linking Rameswaram Island in India with Mannar Island in Sri Lanka. The very nature of "shoals" suggests a formation close to the water's surface, often becoming visible or semi-visible during low tides, underscoring its role as a significant geological and historical pathway.
