 | | From Where Do Rivers Originate | | by Swapna P, Aug 12, 2008 | | At the time when the earth was cooling and the mountains and seas were being formed, there used to be heavy rains. The rainwater flowed down the slopes of the hills and mountains and finally found their way to the open seas. The continuous flowing of the rain down these slopes made a sort of rut or track and these deepened with time. These then formed streams and brooks. With the passage of time they grew in size into huge rivers. | | Comments(0) Liked It: 0 |
