air mass remains unsaturated as it rises.(2 marks)
ANS 5,000m. – detached mass loses approx.. 10C with every 1,000m in altitude (adiabatic
lapse rate). The environmental lapse rate is 8C so the temperatures meet at 5,000m in
altitude. b) If the relative humidity of the detached air mass at ground level...
