Question

Which one of the following is the best example of repeated falls in sea level, giving rise to present-day extensive marshland?

Accepted Answer

Rann of Kutch is a massive expanse of cracked earth, inland from the sea, that promises to take your breath away. The nothingness for miles is both nerve-wracking and stunning with small oases of water bodies and shrub forests doubling up as homes for pink flamingos and wild asses.Tribal hamlets with cylindrical mud bhungas (huts) are the epicenter for Kutchi embroidery, tie and dye, leatherwork, pottery, bell metal craft, and the famous Rogan painting by the only surviving expert family.Approximately 200 km east of the Rann, is the Little Rann of Kutch, which houses the 4953-sq-km Wild Ass Sanctuary. It homes the only remaining population of the chestnut-colored Indian wild ass (khur), as well as blue-bulls, blackbuck, and chinkara.The area was once a sprawling shallow of the Arabian Sea until a constant geological shift closed off the connection with the sea. Over the years, the region eventually became a seasonal marshy salt desert. During monsoons, the marsh fills up with water and the wetland extends from the Gulf of Kutch on the west through to the Gulf of Cambay on the east. In the summers, the water dries to create a crunchy based bed of white salty land.Hence option (d) is the correct answer.
