Lagoons are being used as waterways in ……………………
a. Tamil Nadu
b. Kerala
c. Orissa
d. West Bengal

Answer 1

Hint:
Lagoons are shallow waters, separated from larger waters by reefs, barrier islands or barrier peninsulas. Lagoons are generally classified into coastal lagoons and atoll lagoons. They have also been identified as occurring on sandy and gravel coastlines.

Complete answer:
Due to this separation from the sea, the Backwaters is free from waves. The backwater is one of Kerala's most attractive and economical features. The plant in Kerala is a series of lagoons and salt lakes that stretch parallel to the coast of the Arabian Sea (known as the Malabar Coast) in the southern Indian state of Kerala. This network contains five large lakes connected by artificial and natural canals, fed by 38 rivers, and stretches nearly half the length of Kerala. The backwater is formed by waves and shore currents and forms low barrier islands through the mouths of the many rivers that flow from the western ghats.

Lake Chilika is a freshwater lagoon. It is the largest coastal lagoon in the Puri, khurda and Ganja area of ​​Odisha on the east coast of India at the mouth of the Daya River, which flows into the Bay of Bengal and covers an area of ​​more than 1,100 km.

Hence, the correct answer is option B.

Note:
Most of the coastal lagoons were formed due to the late Quaternary transgression. The transgression began about 18,000 years ago and ended about 3,000 years ago. The average sea level is close to the present. Coastal lagoons are distributed on nearly 15 percentages of the world's coastline.
