Q1. A survey line has a fore bearing of 70°. What is the back bearing of this line?

  1. 250°
  2. 110°
  3. 70°
  4. 290°

Q2. If a surveyor measures the horizontal distance between two points as 150 meters and the vertical difference in elevation as 10 meters, what is the slope between these points? (Slope = vertical difference / horizontal distance)

  1. 0.067
  2. 15
  3. 140
  4. 1.5

Q3. Compare the primary applications of geological surveys and hydrographic surveys in the context of soil conservation engineering.

  1. Geological surveys assess soil and rock stability; hydrographic surveys map water bodies influencing erosion.
  2. Geological surveys map water depths; hydrographic surveys analyze soil composition.
  3. Both surveys are used interchangeably for mapping terrain elevation.
  4. Geological surveys focus on vegetation; hydrographic surveys focus on urban planning.

Q4. A surveyor uses a leveling instrument to measure the height difference between two points. If the instrument reading at point A is 1.250 m and at point B is 2.675 m, what is the elevation difference (B relative to A)?

  1. 1.425 m, B is higher than A
  2. 1.425 m, B is lower than A
  3. 3.925 m, B is higher than A
  4. 3.925 m, B is lower than A

Q5. What is the primary objective of surveying in soil conservation engineering?

  1. To measure soil moisture content accurately
  2. To determine the relative positions of points on or near the earth's surface
  3. To analyze chemical properties of soil samples
  4. To design irrigation systems for agricultural fields

Q6. Compare chain surveying with compass surveying in terms of their suitability for rough terrain.

  1. Chain surveying is more suitable because it requires less equipment
  2. Compass surveying is more suitable because it can measure directions without clear linear paths
  3. Both are equally suitable for rough terrain
  4. Neither is suitable for rough terrain

Q7. Which of the following statements correctly compares the objectives of surveying and levelling?

  1. Surveying determines horizontal positions only, while levelling determines vertical positions only
  2. Surveying and levelling both measure soil properties for conservation
  3. Levelling is a subset of surveying focused on determining elevations
  4. Levelling is unrelated to surveying and used only in construction

Q8. Which surveying instrument is primarily used to measure horizontal and vertical angles accurately in the field?

  1. Theodolite
  2. Leveling Instrument
  3. Chain
  4. Plumb Bob

Q9. What is the primary purpose of using a compass in surveying?

  1. To measure horizontal distances between points
  2. To determine the magnetic bearings of survey lines
  3. To measure vertical angles for levelling
  4. To calculate the area of a survey plot

Q10. A soil conservation engineer needs to map a hilly terrain to plan contour bunding. Which objective of surveying is most relevant in this scenario?

  1. Establishing the chemical composition of soil
  2. Determining the elevation and slope of the terrain
  3. Measuring soil moisture content
  4. Estimating crop yield potential

Q11. Conceptually, how does a topographic survey differ from a cadastral survey in terms of data collected and purpose?

  1. Topographic surveys focus on elevation and natural features; cadastral surveys focus on legal boundaries.
  2. Topographic surveys measure soil composition; cadastral surveys measure water depth.
  3. Topographic surveys are used only in urban areas; cadastral surveys are used only in rural areas.
  4. Topographic surveys are less accurate than cadastral surveys in all cases.

Q12. A surveyor measures a baseline of 150 m using a chain. If the chain length is 20 m but the chain is found to be 0.2 m too long, what is the corrected length of the baseline?

  1. 149.25 m
  2. 150.75 m
  3. 149.50 m
  4. 150.00 m

Q13. In a chain survey, offsets are taken to locate details away from the main survey lines. Which method is commonly used to measure perpendicular offsets?

  1. Using a tape held at an angle to the chain line
  2. Using a cross-staff or optical square to ensure perpendicularity
  3. Measuring diagonal distances and calculating perpendicular offsets
  4. Estimating offsets visually without instruments

Q14. Which of the following best defines surveying in the context of soil conservation?

  1. The process of collecting soil samples for laboratory testing
  2. The science of determining the relative positions of points and the distances and angles between them on the earth's surface
  3. The method of planting vegetation to prevent soil erosion
  4. The technique of measuring rainfall intensity over a watershed

Q15. Compare the uses of a chain and a tape in surveying. Which of the following statements is most accurate?

  1. Chains are more accurate than tapes for measuring long distances
  2. Tapes are generally preferred over chains due to ease of handling and accuracy
  3. Chains are used only for leveling, tapes only for angle measurement
  4. Both chains and tapes are obsolete and never used in modern surveying
