In this article we will discuss about:- 1. Meaning of Rejuvenation 2. Types of Rejuvenation 3. Causes 4. Topographic Expressions. Meaning of Rejuvenation: Rejuvenation simply means acceleration of erosive power of the fluvial process (rivers) caused by a variety of factors. Rejuvenation lengthens the period of cycle of erosion. For example, if the cycle of erosion is passing through senile [...]

It may be pointed out that German scientist Walther Penck pleaded for the rejection of Davisian model of geographical cycle based on time-dependent series of landform development and presented his own model of 'morphological system' or 'morphological analysis' for the explanation of landscape development. The [...]
