Kerala’s unique wetlands locally known as ‘Kayals’ are found in the:

Midlands
Highlands
Coastal areas
River deltas Answer: c

The correct answer is c) Coastal areas.

Kayals are unique wetlands found in the coastal areas of Kerala, India. They are a type of brackish water lagoon that is formed by the interaction of the sea and the rivers. Kayals are important ecosystems that provide a home to a variety of plants and animals. They also play a role in flood control and water purification.

The other options are incorrect because:

  • a) Midlands: The midlands of Kerala are a region of rolling hills and forests. They are not home to kayals.
  • b) Highlands: The highlands of Kerala are a region of mountains and valleys. They are not home to kayals.
  • d) River deltas: The river deltas of Kerala are a region of low-lying land that is formed by the deposition of sediment from rivers. They are not home to kayals.
