What are maps and apps in ArcGIS Online?

Maps in ArcGIS Online serve as visual representations of geographic data, which can include various layers such as points, lines, and polygons to depict features like roads, cities, or land use. These maps are dynamic and interactive, allowing users to pan, zoom, and explore the data visually.

Apps complement the functionality of maps by providing tools and interfaces that facilitate user interaction with the geographic data. They can perform tasks such as data editing, analysis, or enabling users to create custom workflows. In essence, apps enhance user engagement with the data represented in maps, offering more than just a visual display.

The correct answer captures the essence of how maps and apps function in ArcGIS Online. It emphasizes that maps are the visual component, while apps provide the interactivity needed to work with the data effectively.
