Which physical feature runs parallel to the Arabian Sea coastline of Kerala, forming a continuous chain of interconnected brackish water lagoons and lakes known as Kayals?

💡 Solution & Explanation

The coastal belt of Kerala features long barrier beaches and sand spits formed by marine wave action that enclose coastal waters, giving rise to famous backwaters known locally as Kayals. Alternative geological features like glacial moraines or volcanic plateaus are entirely absent from this tropical coastal geography. These water networks historically served as vital inland navigation channels for trade and commerce.
