Study the map of Mumias and answer the questions that follow: a) i) Two types of scales used in the map ii) Four marginal information given in the map iii) The magnetic declination of the area covered

Here are the answers to the questions:

6. Study the map of Mumias and answer the questions that follow.

a) i) Two types of scales used in the map:

• Ratio scale (or Representative Fraction)
• Linear scale (or Line Scale)

a) ii) Four marginal information given in the map:

• Map title
• Map Series Number
• Magnetic Declination
• Key / Legend (Other valid options include: Index to adjoining sheets, Scale, Grid System, Publisher and date)

a) iii) The magnetic declination of the area covered as at 1965:
The magnetic declination as at 1965 is $\boxed{\text{0° 45'W}}$.

b) i) Measure the bearing of Buhuyi dam 5641 from Air photo principle point 14 at grid 6041:
I am unable to measure the bearing as I do not have access to the map of Mumias. This measurement requires the physical map to determine the exact locations and angles.

b) ii) Two methods used to represent relief in the map:

• Contours
• Spot heights (Other valid options include: Trigonometrical stations/pillars, Form lines)
