What distinguishes web scenes from web maps in ArcGIS Online?

In ArcGIS Online, web scenes are specifically designed to visualize and analyze 3D data and phenomena, which distinguishes them from web maps that primarily display 2D geographic information. This capability allows users to interact with spatial data in three dimensions, providing a more immersive experience for understanding complex geographic relationships, elevation data, and other features that benefit from a 3D perspective.

Web scenes enable the representation of terrain and other three-dimensional elements, such as buildings and other structures, enhancing the visualization of spatial relationships in a way that is not possible with traditional 2D maps. This makes it particularly useful in fields such as urban planning, environmental modeling, and any scenario where height or depth is a critical factor in spatial analysis.

The other options describe functionalities or characteristics that do not align with the primary purpose of web scenes. For instance, the notion that web scenes are meant for offline viewing or that they are exclusively used for creating layers does not accurately reflect their intended use within ArcGIS Online. Similarly, stating that web scenes display only 2D geographic information is incorrect, as their significant feature is their capability to present and interact with 3D data.
