Which symbol denotes an aboveground oil or gas pipeline?

• A. Zig-zag solid or dash lines
• B. Solid line
• C. Dash lines
• D. Dotted line

Answer: (B)

This question tests how map symbols indicate whether a pipeline is visible above ground. An aboveground oil or gas pipeline is shown with a solid line because it is a continuous, visible feature along its route. Solid lines signal something that can be seen on the surface, while dashed or dash lines are used for underground pipelines that are buried and not visible, and dotted lines often have other meanings such as proposed features or different types of boundaries. Therefore, the solid line best represents an aboveground pipeline.
