Here are the answers to your questions:

  1. Highlight three factors to consider when setting a weather station.

    • The site should be on open ground, away from obstructions like tall buildings or trees that could affect wind flow and temperature readings.
    • The ground should be level and covered with short grass to ensure accurate temperature and humidity measurements.
    • The station should be easily accessible for regular maintenance and data collection.

  2. i) What is self-exploration? Self-exploration is the process of discovering and understanding one's own identity, including one's values, beliefs, interests, strengths, and weaknesses. It involves introspection and reflection to gain insight into one's inner self.

  1. The local time at Greenwich meridian is 1200hours. What will be the local time at Diani located 40°E of the Greenwich meridian?

  1. Determine the time difference per degree of longitude.

    The Earth rotates 360∘360^\circ in 24 hours.

    1 hour=360∘24 hours=15∘1 \text{ hour} = \frac{360^\circ}{24 \text{ hours}} = 15^\circ

    So, for every 15∘15^\circ of longitude, there is a 1-hour time difference.

  2. Calculate the total time difference for 40∘40^\circ East.

    Time difference=Longitude differenceDegrees per hour\text{Time difference} = \frac{\text{Longitude difference}}{\text{Degrees per hour}} Time difference=40∘15∘/hour\text{Time difference} = \frac{40^\circ}{15^\circ/\text{hour}} Time difference=83 hours\text{Time difference} = \frac{8}{3} \text{ hours} Time difference=2 hours and 23 of an hour\text{Time difference} = 2 \text{ hours and } \frac{2}{3} \text{ of an hour}

  3. Convert the fractional hour to minutes.

    23 hours×60 minutes/hour=40 minutes\frac{2}{3} \text{ hours} \times 60 \text{ minutes/hour} = 40 \text{ minutes}

    So, the total time difference is 2 hours and 40 minutes.

  4. Calculate the local time at Diani.

    Since Diani is East of the Greenwich Meridian, the time will be ahead.

    Local time at Diani=Time at Greenwich+Time difference\text{Local time at Diani} = \text{Time at Greenwich} + \text{Time difference} Local time at Diani=12:00 hours+2 hours 40 minutes\text{Local time at Diani} = 12:00 \text{ hours} + 2 \text{ hours } 40 \text{ minutes} Local time at Diani=14:40 hours\text{Local time at Diani} = 14:40 \text{ hours}

    The local time at Diani will be 14:40 hours\boxed{\text{14:40 hours}}.
