Landforms have a past, present and future. Explain.

The surface of the earth has a great variety of physical features. Each physical feature has a form dynamic and unique and, is known as landform. No landform is permanent. Each landform is changing.

Since the earth came into existence landforms are being created by a large number of internal and external forces. Agents of change are always active in this work such as erosion and deposition of rock material. Filling the basins and valleys, brings changes in the surface of land. Deposition follows erosion and the depositional surface too are ultimately subjected to erosion.
The geomorphic agents such as running water, ice and wind etc. are acting over a long period of time and produce systematic changes leading to sequential development of landforms. We know that most of geomorphic processes are imperceptible functions and can only be seen or measured through their results. The results are landforms and their characteristics.
It is said, in geomorphology, the present is key to the past. In other words, the analysis of the present day characteristics of a landform will reveal us about its past history. In this way, landforms have present, past and future.
