Essay Instructions: Walker Percey claims that most people will not be able to actually experience a place objectively because it has been obscured by systems like education and classification. For example, a tourist would only be able to experience the Grand Canyon in terms of what he expects to find there based on broshures, pictures, experiences like what others have shared with him, etc. For this essay, write an argument about how this place is already defined by our culture and how that may obscure a person's ability to "gaze directly" at the place. Your body paragraphs should focus on an explanation of how someone like a tourist might expect to experience that place and why they might have those expectations. You could also discuss what may happen if the tourist's experience doesn't match what's expected. What happens then?

Suggestions: Prefered if you have Las Vegas as the place for argument in this essay.

I prefer writer named John FitzRandolph to write my argument. If not available another writer is okay, but I need someone like John with good writing skills.

Thanks.

Q: According to the information presented in Chapter 8 "Weather ", thunderstorms and tornadoes are two types of severe weather. Compare and contrast the two types of violent weather. Why is Arizona a good place to study (or "chase") thunderstorms and the Midwest a good place to study (or "chase") tornadoes?

Q1: Based on information here and in the Glacial and Periglacial Landscapes chapter of your text, summarize the reasons why understanding climatology is necessary for interpreting ice core records. Why is this relationship especially important at high elevations in the tropics?

Q2: The Nevado Sajama ice cores enabled Dr. Hardy's group to put together a proxy record of sea-surface temperature that goes back 25,000 years. Using information from Part 1 of your text, explain how changes in sea-surface temperature patterns relate to climate and weather patterns.

Q1: The South Pole has the lowest annual average temperature on Earth. Amazingly though, when measured over an entire year, the South Pole receives an average of 12 hours of sunlight per day -- much the same as all other locations on Earth. Since the length of sunlight can't adequately explain the extreme cold, what does? (Hint: Chapters 5 and 10 in Geosystems, 6/E may provide some background for this answer.)

Q2: Why is it necessary to rethink our standard notions of north, east, south, and west at the South Pole? In other words, why can't those living at the South Pole use these directions in the same way that most of the rest of the world does?

Q1: Why is the introduction of so many exotic species considered an environmental disaster for Hawaiian ecosystems? (Use the chapters on Ecosystems and Biomes for information and ideas to answer this)

Q2: Why does the introduction of a high number of exotic species on O'ahu have the potential to lower overall biodiversity? (Hint: Think about both flora and fauna, niches, and island ecosystems.)

Q1: Based in what you have learned about temperature, humidity, and wind in Parts I and II of your text, do you think that the level of heat stress is the same on a hot day in an arid climate versus a hot day in a humid climate? Explain how the different situations affect the body's response to heat.

Q2: Microclimates in the Grand Canyon depend in part on altitude (the canyon spans over 5000 feet from rim to river). In what area of the canyon would you expect heat stress to be highest and lowest? Why?
