What information does a benchmark provide that a monument does not?

• A. Elevation
• B. Date of creation
• C. Exact property boundaries
• D. Ownership history

Answer: (A)

In surveying, a benchmark provides a precise elevation value tied to a standard datum, which is used for vertical measurements. A monument is simply a fixed marker that shows a location or boundary, but it doesn’t carry or convey a measured height above the datum. So the information a benchmark provides that a monument does not is elevation. Other details like date of creation, exact boundaries, or ownership history may appear on markers, but they aren’t the defining feature of benchmarks.
