How did the tasks of geographical science change from ancient times to the present day?

To answer this question, we can divide the entire history of the development of science into three stages:
Antiquity. At this stage, the main task of science was orientation to the terrain and attempts to describe the surrounding natural phenomena.
New time. The need for the study of new territories, knowledge and description of uncharted areas begins to come to the fore.
Modernity. The main goal of geography is to solve global environmental problems, as well as all kinds of socio-economic problems.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
