People can benefit from the environment that they know it. Geography tries to find answers to the questions of What, Where, Why, and How about the phenomena on earth. Geographers study the characteristics, changes, and interactions of the natural environment and the cultural environment. As a discipline, geography investigates the earth's surface shapes, and changes the space with natural factors such as climate, vegetation, and relief; also examines socio-cultural, economic, ideological and political processes. Within this framework, the fieldwork in geography is very wide, but the special importance it gives to the environment and human relations distinguishes it from other sciences.
