What is an atlas primarily used for?

The primary purpose of an atlas is to serve as a book of maps. Atlases are collections of maps that can represent geographic locations, political boundaries, physical features, and often provide various thematic information such as population density, climate, and transportation networks. They are invaluable tools for visualizing geographic relationships and understanding the spatial distribution of different elements across the Earth. This makes them essential resources for students, researchers, and professionals in fields such as geography, history, and environmental studies. While other options touch on aspects that are important for educational purposes, they do not align with the primary function of an atlas, which is to provide a comprehensive collection of maps for navigation or educational reference.
