Here's my take on systems approach question. Please evaluate!
Systems approach is a methodology used in various fields in order to develop a cause-effect relationship. In geography , though it is primarily applied in the field of human geography , it can be extended to landform analysis to . One of the main theories in landform analysis linked with systems analysis is Isostacy . Isostacy is the feature of maintaining balance ; if there is a difference in pressure on land in one area , there could be an effect elsewhere .
Systems analysis can also be applied to landform development. Landform development can be briefly defined as the eternal battle between endogenic and exogenic forces . Systems analysis of effect of endogenic forces would be as follows: Plate Tectonics --> Sea Floor Spreading --> Ocean-continent boundary interaction --> Fold mountains/Island formation . Considering the exogenic forces such as wind , rivers etc it would be : Slope retreat(of mountains)--> Plateau formation --> Development of Plains --> Erosion by rivers.
Various other process is landform analysis can similarly be linked with systems analysis. By doing so , we can understand processes better and may be help in predicting disasters such as earthquakes , volcanism etc.
P.S : I have no idea if my answer is on the right lines. I was inspired by @Siddharth to write the answer. Since i do not know what is the right way to deal with the answer, i'm not commenting on his answer.
@pratikh - I can't evaluate the direction on which we've written our answers but there are few factual things that I can surely point here.
i. Landform development can be briefly defined as the eternal battle between endogenic and exogenic forces. I think what you've referred here is not exactly landform development but rejuvenation. Of course, Rejuvenation is also a kind of landform development but the latter can also happen under the effect of either endogenic force or exogenic force, exclusively. You have yourself mentioned some of landform development exclusively done by endogenic forces - plate tectonic, ocean boundary etc.
ii. Considering the exogenic forces such as wind , rivers etc it would be : Slope retreat(of mountains)--> Plateau formation --> Development of Plains --> Erosion by rivers. Since your statement is mentioned with an obvious intent on chronology, I think the last one - erosion of rivers can be avoided. Development of graded profile (moderate slopes), plateaus, plains are themselves results of erosion by rivers.
I think the ques could even be ans by highlighting the cyclic and non cyclic theories of landform development . As cyclic theory view landform.as a closed system which depends on time and stage etc whereas non cylic theory view landform.as an open system.which is in dynamic equilibrium with its surroundings . Under non cyclic model you could explain that by being in dynamic equilibrium with its surrounding landform is affected by an change through rejuvination etc .
Yes. I followed this book for those topics which I cannot find in Savindhra. About the book. Average. But I cant find a better source for such topics. If anyone knows, please share.
I have two doubts.. 1. Please tell me how to prepare political geography... 2. What chapters are relevant to be read from majid hussain geographical thoughts..
@aspirant2746 In geographical thought - chapters to be read are * Dichotomy between Determinism and Possibilism * Dualism and Dichotomies in Geography * Quantitative Revolution etc. (Quantitative revolution, Areal differentiation, Locational analysis, System Analysis, Regional Concept) * Models in Geography * Modern Themes (Positivism, Radicalism, Behaviouralism, Humanism, Geography and public policy "Welfare approach")

As I am unable to find some topics in Physical geography - Savindra Singh like Denudation Chronology, Channel Morphology, Slope development, geo hydrology, major gene pool centres etc. will it be a good book to cover them and also other portion of syllabus.
If any body has gone through this book , please give your view.
It will be a great help.
About the book. Average. But I cant find a better source for such topics.
