2. What is the angular difference between true north and magnetic north called?
A. Azimuth
B. Declination
C. Deviation
D. Deflection
Rationale: Magnetic declination represents the angle between true north and
magnetic north.
3. In leveling, the difference in elevation between two points is found by:
A. Adding foresight to backsight
B. Subtracting foresight from backsight
C. Adding height of instrument to foresight
D. Subtracting backsight from foresight
Rationale: Elevation difference = Backsight – Foresight, assuming both are
measured from the same setup.
4. What is the primary purpose of a traverse in surveying?
A. Establish elevations
B. Determine positions of points by angles and distances
C. Establish benchmarks

D. Measure magnetic bearings
Rationale: A traverse provides a framework of control points by measuring angles
and distances between them.
5. The Illinois Coordinate System is based on which type of projection?
A. Mercator
B. Lambert Conformal Conic
C. Azimuthal Equidistant
D. Transverse Mercator
Rationale: Illinois uses the Lambert Conformal Conic projection for state plane
coordinates.
6. What does a "bearing" represent?
A. Angle measured clockwise from east
B. Angle measured from north or south toward east or west
C. Angle measured clockwise from north
D. Directional cosine of a line
Rationale: Bearings are measured from north or south toward east or west, always
less than 90°.
7. A standard section in the Public Land Survey System contains how many
acres?

C. 160
D. 1280
Rationale: One section is 1 square mile = 640 acres.
8. The term “closure” in surveying refers to:
A. A locked instrument
B. A closed boundary line
C. The error between the starting and ending coordinates
D. The last observation in a traverse
Rationale: Closure is the vector difference between computed end coordinates and
known starting coordinates.
9. What is the purpose of an azimuth?
A. Identify a compass bearing
B. Express direction as an angle clockwise from north
C. Define a property boundary
D. Determine slope distance
Rationale: Azimuths express the direction of a line as an angle measured clockwise
from north (0°–360°).
