Question

Which river is considered the “twin” of the Narmada and also flows in a rift valley westward to the Arabian Sea?

• A. Tapi
• B. Mahanadi
• C. Periyar
• D. Godavari

Answer 1

Answer:

A. Tapi

• Correct Answer: Option A - Tapi

• The Tapi (also spelled as Tapti) river is considered the "twin" of the Narmada river because both share several similar characteristics:

• Both the Narmada and Tapi rivers flow westward into the Arabian Sea, unlike most peninsular rivers which flow eastward.

• Both rivers flow through rift valleys. A rift valley is a lowland region formed by the geological process where the Earth's crust is being pulled apart.

• The two rivers run almost parallel to each other in their westward journey through central India.

• Both are among the few major rivers in India that flow west to east, creating unique geographical features.

• The Tapi is the second largest westward flowing river in India after the Narmada, hence earning it the nickname "twin" or "handmaid" of Narmada.

• The other options are incorrect because:

• Mahanadi flows eastward into the Bay of Bengal, not westward into the Arabian Sea

• Periyar, though it flows into the Arabian Sea, is not considered a twin of Narmada and is located in South India

• Godavari flows eastward into the Bay of Bengal, not westward into the Arabian Sea
