Neco Model Questions Vol1 2021 Geography Question 33
Practice objective / multiple choice question 33 from the 2021 Neco Model Questions Vol1 Geography examination.
A region is being assessed for environmental hazard risk using five factors with the following data and weights: - Population density: 150 persons/km² (weight 0.25) - Average slope: 15° (weight 0.20) - Rainfall intensity during rainy season: 12 mm day⁻¹ (weight 0.20) - Vegetation cover: 35 % (weight 0.15) - Soil susceptibility index (0-1): 0.7 (weight 0.20) Normalize each factor to a 0-1 scale using the maximum values: 300 persons/km² for density, 30° for slope, 20 mm day⁻¹ for rainfall, and for vegetation use \(1 - \frac{\text{cover}}{100}\). Compute the weighted hazard index and decide whether the area is classified as high risk (threshold > 0.60).
