Analyzing the world with the five themes of geography helps people better understand connections between people and the earth because it shows us what category things are put into and what they do for the earth. I think this because all of the themes show you different things. Like trade routes or different regions. And those things tell us what is happening and what a place is like around the earth, which helps us organise the geography of the earth.
Human and environment interaction is the most difficult to understand because in my opinion, adapt alter and use are very close together, which makes them hard to distinguish. If you alter the earth you change something on it. If you use the earth you use it to make something with. So in the end they do something similar.
