Book Required: Christopherson's "Geosystems 8th edition"
Read the following five articles (website) and answer the questions below
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?
