What is a "cross-section" in surveying?

• A. A type of measurement used to determine area
• B. A profile view of the terrain along a particular line
• C. A section of land that has been leveled for construction
• D. A report detailing different soil types

Answer: (B)

A "cross-section" in surveying refers to a profile view of the terrain along a specific line. This graphical representation provides a side view of the ground's elevation and contours, allowing surveyors and engineers to understand how the land varies across that line. Cross-sections are particularly useful for visualizing changes in topography, soil layers, and other important features, which aid in planning and design for construction projects, roadways, and drainage systems, among others. By effectively illustrating the relationships between the ground's surface and its subsurface features, cross-sections help professionals make informed decisions based on the specific characteristics of the terrain.
