Topic: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., geographical features and their location- changes in critical geographical features (including waterbodies and ice-caps) and in flora and fauna and the effects of such changes.
3) Climate, vegetation and soils exist in long preserved active equilibrium and this should also apply to landforms. Explain.(250 words)
Why this question:
Landscapes are composed of a diversity of landforms that may be characterized as equilibrium, disequilibrium or nonequilibrium. Equilibrium is a constant relation between input and output or form, toward which a landform tends or around which it fluctuates in time. Because of recent environmental changes and long relaxation times, however, many landforms are not adjusted to present inputs . Thus one has to analyse if this concept is applicable to landforms.
Demand of the question:
Discuss in detail the application of dynamic equilibrium processes on landforms just like the equilibrium that exists between Climate, vegetation and soils.
Directive word:
Explain – Clarify the topic by giving a detailed account as to how and why it occurred, or what is the particular context. You must be defining key terms where ever appropriate, and substantiate with relevant associated facts.
Structure of the answer:
Introduction
The question is straightforward and conceptual , thus there is not much to discuss, one can start by defining what is meant by Equilibrium.
Body
Explain in detail what you understand by Equilibrium. Topography acts as a template for numerous landscape processes that include hydrologic, ecologic, and biologic phenomena. These processes not only interact with each other but also contribute to shaping the landscape as they influence geomorphic processes.
First explain with examples the dynamic equilibrium that exists between Climate, vegetation and soils with examples , then move on to explain how it can be applied to landforms too.
Conclusion
Conclude with a balanced opinion based on the points you present.
