Coastal Plains

The unique phenomenon you described, where the seawater recedes several kilometres twice a day, exposing the seabed for walking, can be seen at Chandipur Beach in Odisha, India. Chandipur Beach is also known as the "hide-and-seek beach" due to this fascinating tidal phenomenon. The receding water allows visitors to explore the seabed, revealing seashells and marine life during low tide. Hence, option C is the correct answer.

* **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.
