1. Dynamic Rejuvenation
2. Eustatic Rejuvenation
3. Static Rejuvenation
1. Topographical Discordance
This can be defined as decrease in uniformity of valley of rivers Basic cally this denotes creation older topographic forms above and younger topographic forms below the older one.
|Example of Polycylic valleys and paired river terraces|
- Topographical discordance leads to formation of Valley in Valley topography' or paired terraces.
- Basically this happens due to rise in the land of coarse of river. Which lead increase in down cutting of the river valley leading to creation of a paired terraces on both sides due to fall in river.
- Repeated upliftment of land form cause creation of new paired terraces after each uplift of land.
