Geography is the study of the earth and its features and of the circulation of life on the Earth. A literal transformation would be "to describe the Earth". The first person to use the word "geography" was Eratosthenes (275-195 B.C.). Four historical civilization in geographical research are the spatial analysis of natural and human phenomena, area studies, study of man-land relationship, and investigate in earth sciences. Nonetheless, modern geography is an all-inclusive discipline that foremost seeks to understand the world and all of its human and natural complexities-- not merely where things are, but how they have changed and come to be. It is said to be the "mother of all math" and "the synthesizer of information." Geography is mainly divided into two main branches - human geography and physical geography.
