【正文】 STP 1 Choose the best answer for the following multiplechoice question. If you have trouble answering the question, use the process of elimination to narrow your choices. STP 2 1. Given the information shown in the bar graph on page 129 of your textbook, which city is most likely located east of the fall line in the eastern United States? A City 1 B City 2 C City 3 D City 4 Click the mouse button or press the Space Bar to display the answer. TestTaking Tip To determine which city is east of the fall line, remember that the fall line is where the higher land of the Piedmont drops to the lower Atlantic Coastal Plain to the east. Eliminate those choices that do not indicate a city on the coast, near sea level. GeoFact 1 The Appalachian Trail The National Geographic Society Tree Click on a hyperlink to view the corresponding slide. GeoFact 1a The Appalachian Trail is a 2,000 mile (3,200 km) hiking path through some of the most beautiful scenery in the eastern United States. Earl V. Shaffer distinguished himself by being the first person to hike the entire trail in 1949, the first to hike the trail in both directions, and, in 1999 at the age of 80, the oldest person to plete the trek from Mount Katahdin in Maine to Springer Mountain in Georgia. GeoFact 1b The National Geographic Society Tree, a coast redwood growing in California’s Redwood National Park, is a leading contender for the world’s tallest living tree. Measured in 1995 at feet (111 m), the tree has branches that sweep in 50foot (15m) arcs. Interdisciplinary Connection 1 Geology The Canadian Shield is a horseshoeshaped expanse of rock that covers half of Canada. Some of the rock formations in the Canadian Shield are 2 billion to 4 billion years old, making them some of the oldest formations in the world. Culture Note 1 The Dust Bowl Writer John Steinbeck chronicled the plight of those who lost their farms in the Dust Bowl in his Pulitzer Prizewinning novel, The Grapes of Wrath, written in 1939. SkillBuilder 1 Reading a Relief Map When you plan a walk, do you prefer an easy stroll along flat ground, or do you look for a challenging hike up and down steep hills? By using a relief map, you can determine the elevation of the terrain you are going to cover. SkillBuilder 2 Learning the Skill A relief map is a special purpose map that shows variation in height, or elevation, of land areas. All elevation is measured from sea level, the average level of water in the world’s oceans. Mapmakers label this elevation level zero feet (0 m). The actual elevation of some places is shown as a negative number because they lie below sea level. ? It is not possible for a relief map to show the elevation of every single inch of land. As a result, areas are grouped together. A map may show all areas with an elevation between sea level and 1,000 feet (305 m) colored green. Within that area no hill will be higher than 1,000 feet (305 m) and no valley lower than sea level. Click the mouse button or press the Space Bar to display the information. Reading a Relief Map SkillBuilder 3 Follow these steps to read a relief map: ? Learning the Skill Click the mouse button or press the Space Bar to display the information. ? Note the title of the map. ? ? Study the map key. Relief maps generally use colors or shaded areas to identify elevation. ? ? Compare the relief map with other maps. Observe how elevation affects climate, population distribution, and economic activity in an area. Reading a Relief Map SkillBuilder 4 Practicing the Skill Refer to the relief map on page 126 of your textbook to answer the following questions. 1. What is the color of the map’s highest elevation? 2. What elevation range does the color green indicate in feet? In meters? The color of the highest elevation is orange. Click the mouse button or press the Space Bar to display possible answers. The color green indicates 0 to 1,000 feet, or 0 to 300 meters.

What color is the elevation range of 2,000 to 5,000 feet (600 m to 1,500 m)? 4. At what elevation is the state of Mississippi? The color of the elevation range is light orange. The elevation of Mississippi is 0 to 1,000 feet. Refer to the relief map on page 126 of your textbook to answer the following questions.
