Question

In which categories (portions) relief may be divied?

Answer 1

preliminary step to study the geomorphological features or morphometric study
of any area is analysis of its relief feature. The variation of earth surface or a part of it
becomes focus of a geomorphic study of landforms. The meaning of term relief may be
defined as the difference in elevation of any part of the earth's surface or relative vertical
inequality of land surface. Relative relief is among the techniques, those are effectively
capable of presenting three dimensional relief characteristics with the help of twodimensional maps, without considering sea level. Relief and other geomorphic elements are
also based in differences in elevation. These morphometric elements are absolute relief,
relative relief, slope and dissection index, etc. who, help to classify morpho units of terrain.
However, in this chapter, elements, that are directly related with relief have been discussed.
These elements are known to help in analysis of any landform and also in categorizing
landforms into various morphounits and their relation with geology and hydrology of the
area.
The morphometric elements are relative relief, absolute relief, slope, and dissection
index and drainage characteristics. These elements of morphometry are valuable in
dividing the landforms into various morphounits and their relation with geology of a
particular area, climatic and hydrological conditions as well as classification and sub
classification of landforms i.e. absolute relief, slope, relief profile etc.. So, relief analysis
becomes essential for studying a given area. Relief also indicates the past geological events
occurred in the particular area.
