In the second issue of the Sepehr journal, we defined Geography in simple words as a science that examines the observable differences over the Earth’s surface, with the benefit of utilizing these observations for various aims.
In this issue, we take a step further and state that the cause of these differences is either the Earth (the Nature itself) or human being. There is not a general agreement on which of the above-mentioned factors has a more important role in creating these differences, but no geographer has so far denied the importance of either of these two factors. The present author believes that if anyone knows the Earth and its characteristics well, it will easily understand many of the geographic concepts; there are a lot of issues in understanding the Earth, but we can examine all of these issues under three headings: the shape of the Earth, the movements of the Earth and the structure of the Earth.
