Discussion Question: Essentials of Geography A+ Chapter 1 does a nice job introducing the Physical Earth Sciences with the traditional scientific methods and systems. However, Physical Geography exemplifies understanding spatial patterns. For example, we could research an area's cases of West Nile Virus using a table filled with location and number of deaths and it would be useful. However, an even better way to look at the information in order to search for an underlying pattern and an explanation would be to map the data. For the Chapter 1 Discussion, find a thematic map from your house, the Newspaper, the Internet, the textbook, or wherever you find one! Be sure to include the source such that any of us can get our hands on the same information/map. First DESCRIBE the patterns that you see. Then, INTERPRET the reasons for the pattern. For example,the figures above and below are maps with information plotted. Remember, descriptions are not arguable. Descriptions are factual…
