1. Solar radiation increases or decreases with elevation depending on cloud cover.
       
2. Why is runoff commonly higher in high elevation (1) and what are the benefits(2) and dangers(3) associated with this?
   (1) higher precipitation/evapotranspiration ratio
   (2) hydrolectric power.
   (3) erosion
    
3. The air temperature measured at meteorological stations often has little in common with that experienced by organisms Because the "microclimate" is modified by topography and plant morphology.
      
4. What is the approximate air temperature at 3000 m when the temperature measured at 1000 m is 15 °C?
   4 °C
      
5. The partial pressure of CO₂ and oxygen declines with altitude, the concentration or mixing ratio of CO₂ and oxygen remains Constant.
