Which one of the following is NOT a west flowing river ?
- A.Periyar
- B.Bharatpuzha
- C.Pamba
- D.Tamraparni
Correct answer
Explanation
The correct answer is D, Tamraparni. The Tamraparni rises in the Agasthyamalai hills of the Western Ghats and flows east through Tirunelveli and Thoothukudi districts of Tamil Nadu into the Gulf of Mannar.
Most short rivers of Kerala rise on the western slopes of the Western Ghats and run quickly west into the Arabian Sea or its backwaters. The Tamraparni, though it also rises in the Ghats, drains the eastern side, so it is one of the east-flowing rivers of the peninsula. It is the only perennial river of Tamil Nadu's far south and was famous in ancient times for the pearl fisheries at its mouth.
A is wrong because the Periyar, Kerala's longest river, flows west into the Vembanad backwaters and the Arabian Sea.
B is wrong because the Bharatpuzha (Bharathapuzha), Kerala's second-longest river, flows west through the Palghat Gap to the sea at Ponnani.
C is wrong because the Pamba flows west past Sabarimala into Vembanad Lake.
Exam tip: Kerala's Periyar, Bharatpuzha and Pamba flow west; Tamil Nadu's Tamraparni and Vaigai flow east.

- C.A weedicide that kills the forest roots
- D.A means of levelling the slope
Show answer
In slash-and-burn farming the felled trees and undergrowth are dried and burnt on the spot, and the ash left behind is rich in potash and other mineral nutrients, which the cultivator depends on because no chemical fertiliser or farmyard manure is used.
