Click the mouse button or press the Space Bar to display the answer.
Landforms (cont.) Which areas of the region would you predict are the most densely populated? Why do you think so? People tend to settle near sources of freshwater and in mild climates. Mountaintops are too cold and the deserts are too dry for many people to live there. People would settle in the Great Plains because the farmland is rich and abundant. Some of the islands are probably crowded, as are most coastal areas where large cities are located. Other populated areas border lakes and rivers that serve as transportation arteries.

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 1

Reading a Relief Map 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. SkillBuilder 2

Reading a Relief Map Learning the Skill
Follow these steps to read a relief map:  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.
