Using a physical geography text, such as Geosystems, add appropriate labels to Figure 29.2 in the spaces provided at the bottom of Figure 29.2: tropical rain forest, temperate deciduous forest, needleleaf forest, tundra, and ice and snow. Next, assuming the normal lapse rate is in effect, beginning at sea level and the rain forest label, assume the temperature to be at 27°C (80°F). Assume the labels are spaced at 600m (2000 ft) intervals and calculate the temperature on this particular day at each label elevation. Calculate five temperatures decreasing with altitude (600, 1200, 1800, 2400, and 3000 m) and record your answers on the lines along the right side of the mountain in Figure 29.2.
