Which one of the following is the best example of repeated falls in sea level, giving rise to present-day extensive marshland?
Explanation
* The Rann of Kutch, located in the Thar Desert of Gujarat, India, is a vast seasonal salt marsh.
* Geological evidence suggests it was once a shallow extension of the Arabian Sea.
* Over time, due to a combination of factors like tectonic plate movement and climatic changes, the sea level receded repeatedly, leaving behind saline deposits and creating the marshland we see today.
* During the monsoon season, the Rann fills with water, transforming into a shallow lake, but dries up again in the summer, leaving behind a vast expanse of cracked white salt flats.
* Bhitarkanika Mangroves: Located in Odisha, Bhitarkanika Mangroves is a protected wetland area and a UNESCO Ramsar site. It is home to saltwater crocodiles, migratory birds, and various plant species. The mangroves provide coastal protection and support local fishing communities.
* Marakkanam Salt Pans: Marakkanam, in Tamil Nadu, is one of India's largest salt-producing regions. The salt pans are a major source of salt production, and the area also attracts migratory birds, including flamingos.
* Naupada Swamp: Located in Andhra Pradesh, is an important wetland for migratory birds and aquatic life. The swamp supports a wide variety of wildlife, including endangered species like the smooth-coated otter.
