(i) Two points of difference between a port and a harbour are-
| Port | Harbour |
|---|---|
| Ports are man-made commercial places built along the coastline. | Harbours are natural or created places, connecting a piece of land with a large water body, which serves as ports. |
| The main purpose of ports is loading and unloading of cargo ships. | Harbours are utilised mainly for providing safe parking or anchorage to ships. |
