Use the appropriate adiabatic lapse rates and the figure below to answer the following question.

(Hint: Notice that the elevation change between points is not consistent. There is a 1000m change between the starting point and point A, but there is only a 100m change between points A and B, B and C, and C and D. If the dry adiabatic lapse rate is 10 degrees per 1000m, then it should be 1 degree for 100m. The wet adiabatic lapse rate will also need adjusting for the 100m change. Also, note that the air is ascending, which means it will be expanding and cooling in temperature). Starting Point: 100 m and 25ºC A: 1100 m B: 1200 m - switch to WALR C: 1300 m D: 1400 m
