Question 1 View Details
A map of a local river basin is drawn at a scale of 1 cm : 250 m. The map shows three points A, B and C with the following coordinates measured with a ruler (in centimetres): - A (2.3 , 4.7) - B (5.8 , 7.1) - C (8.0 , 3.2) The river flows from A to B to C. The contour interval on the map is 10 m. The elevation at point A is 120 m and at point C is 80 m.
Question Parts
(a)
Calculate the actual straight‑line distance AB and BC in kilometres.
(b)
Determine the bearing of line AB from point A (express the bearing to the nearest degree).
(c)
Estimate the minimum gradient of the river between A and C, expressed as a percentage, assuming a straight line between the two points.
(d)
State two possible sources of error that could affect the gradient calculated in part (c).

Question 2 View Details
A rectangular plot of land is represented on a plan drawn at a scale of 1 : 500. The dimensions measured on the plan are: - Length = 12.5 cm - Width = 8.0 cm A paved pathway of width 0.6 cm runs parallel to the length and is located 3.0 cm from the northern edge of the plot, thereby dividing the plot into a northern section and a southern section.
Question Parts
(a)
Calculate the actual area of the whole plot in hectares.
(b)
Determine the actual width of the pathway in metres.
(c)
The northern section of the plot (including the pathway) is to be used for planting maize. Maize requires a spacing of 0.75 m between plants in a row and 0.60 m between rows. Estimate the maximum number of maize plants that can be accommodated in the northern section.
(d)
State one advantage and one disadvantage of using a scale of 1 : 500 for land‑surveying purposes.

Question 3 View Details
A topographic map of Nigeria is drawn with a scale of 1 cm = 100 km. The map shows the following geographic coordinates of two cities: - Lagos: 6°27' N, 3°22' E - Kano: 12°00' N, 8°30' E Using the information given, answer the following questions.
Question Parts
(a)
Calculate the north‑south distance between Lagos and Kano. (Take 1° latitude = 111 km.)
(b)
Calculate the east‑west distance between the two cities. Use the average latitude of the two cities to adjust the length of a degree of longitude (1° longitude = 111 km × cos average latitude).
(c)
Using the north‑south and east‑west distances obtained above, determine the straight‑line distance between Lagos and Kano (assume a right‑angled triangle).
(d)
If a commercial aircraft flies the straight‑line route at a constant speed of 600 km/h, estimate the flight time in hours and minutes, ignoring wind and other factors.

Question 4 View Details
Synoptic observations recorded at three weather stations on the same day are given below. | Station | Latitude (°N) | Longitude (°E) | Pressure (hPa) | Wind direction (from) | |---------|---------------|----------------|----------------|-----------------------| | A | 5.0 | 6.0 | 1012 | NE | | B | 7.0 | 8.0 | 1008 | E | | C | 6.0 | 10.0 | 1005 | SE | Assume 1° latitude = 111 km and 1° longitude = 111 km × cos average latitude. Air density ρ = 1.2 kg m⁻³ and the Coriolis parameter f = 1.0 × 10⁻⁴ s⁻¹. Answer the following questions.
Question Parts
(a)
State the direction of the pressure gradient between stations A and B. Explain briefly how you obtained the direction.
(b)
Based on the pressure pattern and the wind directions at the three stations, identify the type of frontal system most likely affecting the region (cold front, warm front, stationary front, or occluded front). Give a concise justification.
