Which of the following rivers forms a famous estuary rather than a delta on the western coast of India?

💡 Solution & Explanation

The Tapi river flows westward into the Arabian Sea through a rift valley, creating an estuary rather than a delta because of steep gradients and high current velocities that prevent sediment deposition. Common alternatives like Mahanadi, Godavari, and Kaveri flow eastward into the Bay of Bengal, developing extensive deltaic networks due to gentle slopes and heavy silt loads.
