The two main branches of geography are physical geography and human geography, and other branches it seems to depend as there are a number of different subfields. Two of the biggest are environmental geography and cartography, for example.
Explanation:
Cartography involves the actual charting and mapping of physical space which has become more advanced and detailed with technological changes. Gone are the days of having to rely on navigation skills and the eyes of a cartographer for mapping the far away reaches of the world.

There is also a focus on the consequences of this interaction and how to avoid certain activities that have an impact on the environment.
