A likely natural feature in an extremely densely populated area would be a well watered, fertile plain. An example is the Northern plain of India also called the Indo - Gangetic plain. It s on one of the world's most densely populated area per square kilometer. This plain is formed from the flood plains of three great river systems - the Indus, the Ganga and the Brahmaputra. The soil cover in the plain is rich and fertile and water is found in plenty. These factors combined with a favorable climate makes it one of the most intensely farmed and populated areas in the globe.
The process of erosion can best be described as the movement of weathered materials by: wind water or other natural agents.
