Neco Model Questions Vol1 2025 Geography Question 37
Practice objective / multiple choice question 37 from the 2025 Neco Model Questions Vol1 Geography examination.
Three zones (A, B, C) in a region lie at altitudes of 200 m, 800 m and 1500 m respectively. At sea level the average annual rainfall is 1200 mm and the mean temperature is 30 °C. For every increase of 300 m in altitude, rainfall decreases by 10 % of the sea‑level value, and temperature falls by 0.6 °C per 100 m. Using a simplified Thornthwaite index \(\text{PET}=\dfrac{T^{2}}{R}\) (where \(T\) is temperature in °C and \(R\) is rainfall in mm), calculate the PET for each zone and state which zone has the highest PET, giving its PET value to two decimal places.
