1. The four major parts of the Earth System are the lithosphere, biosphere, hydrosphere, and atmosphere.
   
   
2. Weather is the state of the atmosphere at one time and place, while climate would be the average of weather observations over a period of time.
   
   
3. One is more likely to use a bar graph to represent non-continuous, highly variable data such as precipitation amounts over time.
   
   
4. Isopleths connect points of equal value on a map. Thus, parallels would be circles connecting equal latitude on a polar map projection. [second blank could also be "latitude lines"]
   
   
5. The most abundant of the “chemically active” gases in the Earth’s atmosphere is molecular oxygen.
