Question

• A. Pamba
• B. Chalakudy
• C. Bharathapuzha
• D. Periyar

Answer 1

Answer:

D. Periyar

• Correct Answer: Option D - Periyar

• The Periyar River is one of the longest rivers in Kerala and plays a vital role in the state's geography and economy. The river originates from the Sivagiri hills of the Western Ghats and flows through Idukki district, where it is dammed to form the Periyar Lake (Thekkady). From there, it continues its journey through Ernakulam district.

• As the Periyar River approaches its final stretch, it splits into two major distributaries - Mangalapuzha and Marthandan - near Aluva. These branches continue their course and ultimately empty into the Vembanad Lake, which is the largest lake in Kerala and part of the Ramsar Convention on wetlands of international importance.

• The Periyar is often called the "Lifeline of Kerala" due to its significance for irrigation, hydroelectric power generation, and drinking water supply for many towns and cities including Kochi. The Periyar River system supports the rich biodiversity of the region and has significant historical and cultural importance for Kerala.
