2Upon completion of Chapter: Map Features you will: Understand how to utilize a map key to interpret different types of mapsUse a scale on a map and convert distances from inches to centimeters and miles to kilometersIdentify locations on a map using latitudinal and longitudinal coordinatesRecognize the importance of the Prime Meridian and Equator and how the two lines identify hemispheres and determine seasons.

4Country BorderCountry CapitalOther CityOften a map has a key, or legend. The key shows the symbols and colors used on the map, and what each one means.
5A map key explains what the symbols, shading, and colors on a map represent. Symbols range from simple dots and circles that represent cities and capitals to tiny drawing that represent types of manufacturing and industry or agriculture.Shading and colors are used to show elevation, population density, political division, and so on.The map key for the map of China you have shows a combination of shading and drawings to represent economic activity and resources.
6Map Key ActivityUsing the map of China, please answer the following questions:How many different types of shading are represented on the map key?What symbol is used to represent oil?Which part of China is least developed economically?Describe the economic activity and resources around Beijing.Based on the map, which city in China has the most varied manufacturing and industry?Why does the map use a combination of shadings and drawings to show economic activity and resources?Click here to download the map used for this activity:
7Maps are drawn to different scales, depending on their purpose. Somemapsshow large areas and need larger scales, whileother maps show smaller areas and need smaller scales

11They are measured in degrees from 0-90 in both hemispheres Parallels of LatitudeParallels of Latitude go around the Earth.The Equator separates the Earth into two hemispheresEach degree equals about 70 miles.How many miles is it from 0 to 90 North?How about 0 to 90 South?They are measured in degrees from 0-90 in both hemispheres
12Meridians of Longitude 0-180East0-180WestThe Prime Meridian is 0 LongitudeThe same line on the other half of the world is 180
13Meridians of Longitude As the Prime Meridian goes around the other side of the globe the degree changes to 180180180 Degrees is also where you find the International Date Line
14Crossing the IDLThere is a 14 hour time difference between Sydney and Los Angeles. If the flight to Los Angeles takes 14 hours, I arrive at the same day and time I departed.Arrive L.A., CA, USA at 8:00 a.m. TuesdayDepart Sydney NSW, AU at 8:00 a.m. Tuesday
15The “Tropics”The area bounded by the Tropic of Cancer on the north and Tropic of Capricorn on the south is known as the "tropics."This area does not experience seasons because the sun is always high in the sky.Only higher latitudes, north of the Tropic of Cancer and south of the Tropic of Capricorn, experience significant seasonal variation in climate.
16Map Projections Maps are drawings that show regions on flat surfaces Maps cannot show the correct size and shape of every feature on the Earth’s surfaceNo map projection can show accurately the correct shape and distance for the entire Earth’s surfaceBecause of this problem, different types of maps are used for different reasons
17Map ProjectionsWhen you flatten a globe in order to make a map you create global gores.In order to make a map with these gores you have to distort the images.
18Same Shape Map Projections Mercator MapThis map shows accurate shape and direction but it distorts distance and size.In other words, the map shows exactly WHAT the continents look like, but not where they are and how big or small they are.
19Equal Area Map Projections Map projections that show the correct size of landmasses are called equal-area maps.In order to show the correct size of landmasses, these maps usually distort shapesThe distortion is usually greater atthe edges of the map and less at the center.
20Equal Area Map Projections In order to make an equal area map, the gores are squeezed together at the top and bottomRobinson MapThe Robinson map is a compromise between theMercator and equal-areaIt keeps the size and shape relationships of most continents and oceans, but distorts the size of the polar regions.
21Physical MapsPhysical maps represent what a region looks like by showing its major physical featuresPhysical maps also often show elevationand reliefElevation, indicated by colors, is the height of the land above sea level. Relief, indicated by shading, shows how sharply the land rises or falls.
