Gce Model Questions Vol1 2020 Geography Question 5

Three regions (A, B and C) are being compared for climate classification and tea‑plant suitability. The data are:\n\nRegion A: altitude 800 m, observed mean annual temperature 16 °C, annual rainfall 1900 mm.\nRegion B: altitude 200 m, observed mean annual temperature 22 °C, annual rainfall 2100 mm.\nRegion C: altitude 1500 m, observed mean annual temperature 12 °C, annual rainfall 1600 mm.\n\nAssume a standard lapse rate of 6.5 °C per 1000 m to convert observed temperatures to sea‑level equivalents. Using the simplified rule that a region with sea‑level mean temperature below 22 °C is classified as Köppen Cfb (temperate oceanic), identify which regions are Cfb. Tea cultivation requires rainfall between 1500 mm and 2500 mm and a mean temperature at the growing altitude between 18 °C and 22 °C. Indicate which region(s) meet the tea‑cultivation requirements.
