Why is difficult to forward a single and uniform meaning to the term geography

It is difficult to forward a single and uniform meaning of the term geography because geography as a science is extremely broad, encompassing multiplicity of concepts and areas of study.

Geography is a science that aims to study the Earth's surface and the spatial distribution of significant phenomena in the landscape. It also studies the reciprocal relationship between man and the environment (Human Geography). One of the central themes of geography is the relationship between man and nature. Nature is understood as the forces that generated or contribute to shape the geographic space, that is, the dynamics and interactions that exist between the atmosphere, lithosphere, hydrosphere and biosphere. Man is understood as an organism capable of considerably modifying the forces of nature through technology.
