ALWAYS provide units with your answers, even if it seems obvious.

1. WatchNational Geographic: Earth’s Atmosphereagain to find the answers for this question.

a. What percentage of all of Earth’s air is in the troposphere? (You will need to convert the fraction given in the web site to a percentage. Do this by dividing the number out and multiplying by 100.)

b. How high above the equator does the troposphere extend in kilometers?   In miles?

c. Typically, how does the temperature change as you go higher in the troposphere?

d. What are the 4 influences on climate that are listed and described on the ‘climate’ page of the website?

e. From the video, what inventions have allowed humans to inhabit all ofEarth’s climates?

NOTE: The previous question has several parts each of which needs to be answered. Many questions will be this way. Please watch out for them.

2. Why is latitude the most important consideration when it comes to controls on Earth’s climate?

3. Continentality and marine influence can be seen by comparing the climographs for cities at similar latitudes but varying distances from the oceans. Pick two pairs of cities in the United States. IN each pair one city should be on the coast and the other inland. They should be at about the same latitude. That will allow the pairs to demonstrate this control on climates. You may pick any two pairs as long as they meet the two criteria. Go to this website RSS climographs. Make a climograph for each of the four cities. (Note: This site lists hundreds of US cities, but not all of them. You may have to adjust your city choices based on what data you can find on the RSS site.) Copy and paste the four climographs into this question set. Then fill in the table below with the requested information. INCLUDE UNITS IN EVERY ANSWER!!! Remember that *F and F* have somewhat different meanings and uses.

~ computed as highest average high minus lowest average low

4. Based on the information you gathered for question 2, make a general statement about the significance of continentality to the cost of living. (You may be as far ranging as you like in this answer. Think about all the decisions made and money spent based on temperature range and average highs and lows. Just for one idea, very few people in Seattle have air conditioning while pretty much everyone in Fargo does (or dearly wishes they did).)

5. Describe a land sea breeze. A diagram may be a useful way to illustrate your answer. Be sure to explain or show the difference between the daytime and nighttime situation.

6. What is albedo? Why is albedo an important concept? For each of the following land surfaces indicate whether the albedo would be relatively high or relatively low.

7. What is a microclimate? Describe an example of a microclimate and what it would be like to live within that microclimate. (Imagine you are an ant or a blade of grass, for example.)

8. Give the full name and briefly explain each of the terms in the formula: Surface Wind = PGF+CE+CF+F

9. Why do Highs form? Describe the movement of surface air and upper level air around a High. You may use a diagram in your answer but be sure to label each component.

10. Why do Lows form? Describe the movement of surface air and upper level air around a Low. You may use a diagram in your answer but be sure to label each component.
