Why do geographers study religion?

to reduce the spread of pandemics by restricting religious diffusion

to explain religion's role in regional conflict

to prevent countermigration streams

to understand how religion affects land use

To explain religions role in regional conflict because conflicts are distributed all around the globe all with specific reasons. One of the many reasons that contribute to global conflicts in religion and culture differences. Simply, there's tension between the two and geographers study the cycles of that. If I'm wrong. Well I took Human Geography so maybe it is the fourth one but in human geography terms it's the second

Pretty sure it's to understand how religion affects land use (how religion and the environment interact)
