1. The primary purpose of surveying is to:
A. Design buildings
B. Measure and determine positions of points on Earth’s surface
C. Manufacture instruments
D. Analyze soil composition
Answer: B
Rationale: Surveying involves measuring distances, angles, and positions to
establish locations on the Earth's surface.
2. A surveyor uses a benchmark to establish:
A. Horizontal distance
B. Reference elevation
C. Property ownership
D. Soil type
Answer: B
Rationale: A benchmark is a fixed reference point with a known elevation.
3. The basic unit of length in the U.S. customary surveying system is:
,A. Meter
B. Foot
C. Kilometer
D. Centimeter
Answer: B
Rationale: Surveying in the United States commonly uses feet for linear
measurements.
4. Precision refers to:
A. Closeness to the true value
B. Degree of repeatability of measurements
C. Size of an instrument
D. Speed of measurement
Answer: B
Rationale: Precision describes how closely repeated measurements agree with
each other.
5. Accuracy refers to:
A. Agreement with the true value
B. Number of measurements taken
C. Instrument weight
D. Measurement speed
Answer: A
Rationale: Accuracy indicates how close a measurement is to the actual value.
6. A total station measures:
A. Angles and distances electronically
B. Soil density only
,C. Weather conditions only
D. Property taxes
Answer: A
Rationale: A total station combines electronic distance measurement with angle
measurement.
7. The instrument commonly used to measure horizontal and vertical angles is
a:
A. Level rod
B. Theodolite
C. Measuring tape
D. Plumb bob
Answer: B
Rationale: A theodolite is designed for precise angle measurements.
8. A level instrument is primarily used to determine:
A. Elevation differences
B. Property ownership
C. Soil conditions
D. Magnetic declination
Answer: A
Rationale: Levels are used to measure differences in elevation between points.
9. A plumb bob establishes:
A. A horizontal line
B. A vertical reference line
C. A distance measurement
D. An elevation value
, Answer: B
Rationale: A plumb bob uses gravity to establish true vertical alignment.
10. A survey rod is used to:
A. Measure elevations with a level
B. Measure angles
C. Record legal descriptions
D. Calculate taxes
Answer: A
Rationale: A leveling rod provides readings used to determine elevations.
11. The horizontal distance between two points is measured along:
A. A vertical line
B. A level plane
C. A slope only
D. A curved surface
Answer: B
Rationale: Horizontal distance is measured on a horizontal plane.
12. The SI unit of length is:
A. Foot
B. Inch
C. Meter
D. Mile
Answer: C
Rationale: The meter is the standard SI unit of length.
