Well you can start of like Geography is the study of places and the relationships between people and their environments. geographers explore both physical properties of Earth’s surface and the human societies spread across it,geography seeks to understand where things are found,why they are, and how they develop and change over time and for regions i’m not sure where you are located but for instance I live in the U.S but an example of an region can be North America ,U.S and Mexico and the geography they share is grand mountain ranges ,lush expansive soil and a range of climate related and ecological variations and someone who is not a geographer would still use geography tools is because lets say if you go on a vacation and you go out of state more than likely you’ll need something to guide you and your options could be a map compass and things like lighters flashlights and something for comfort and how they use it today is like now when people venture out or go places they being everything they need maps,food,portable shelter and most importantly our cellphones. Hope this was a good explanation took me some time but not a prob:)
