NAME:___________________________________ HOUR:____________ GEOGRAPHY SKILLS HANDBOOK Geography skills provide the tools and methods for us to understand the relationships between people, places, and environments. We use geographic skills when we make daily personal decisions-where to buy a home; where to get a job; how to get to the shopping mall; where to go on vacation. Community decisions, such as where to locate a new school or how to solve problems of air and water pollution, also require the skillful use of geographic information. This Geography Skills Handbook introduces you to the basic geographic tools-globes, maps, graphs-and explains how to use them. These resources will help you get the most out of your geography course-and provide you with skills you will use for the rest of your life. Thinking Like a Geographer Skills for Learning Geography: Geography educators have identified a set of 5 skills that are key to geographic understanding. SKILL EXAMPLES TOOLS & TECHNIQUE 1 Latitude, Longitude, and Location: Geography is often said to begin with the question: _________________? Although this question can be answered in many ways the basic tool for finding the answer is _____________________. Lines on globes and maps provide information that can help you locate places. These lines cross one another, forming a pattern called a ____________ _____________________. This system helps you find exact places on the Earth’s surface. Latitude Parallels: North latitude: South latitude: Longitude Meridians: Prime Meridian: East longitude: West longitude: The Global Grid Absolute location: Minutes: 2 From Globes to Maps A ________________________ is a scale model of the earth. Because the earth is round, a globe presents the most accurate depiction of geographic information such as area, distance, and direction. However, globes show little close-up detail. A ___________________ is a symbolic representation of all or part of the planet on a flat piece of paper. Unlike globes, maps can show small areas in great detail. Another advantage of printed maps is that they can be folded, stored, and easily carried from place to place. From 3-D to 2-D: Cartographers: Issues: How Map Projections Work: Map Projections: Planar Projection Cylindrical Projection Conic Projection 3 Common Map Projections: The _________________ ___________________of the earth cannot be shown accurately on a flat map. Every map projection stretches or breaks the curved surface of the planet in some way as it is flattened. Distance, direction, shape, or area may be distorted. ____________________________ have developed many map projections, each with some advantages and some degree of inaccuracy. Four of the most popular map projections, named for the cartographers who developed them, are shown below. Winkel Tripel Projection Robinson Projection Goode’s Interrupted Equal-Area Projection Mercator Projection 4 Reading a Map In addition to ___________________ and the lines of ____________________ and ______________________, maps feature other important tools to help you interpret the information they contain. Learning to use these map tools will help you read the symbolic language of maps. Key/Legend: Every map has different symbols, to assure that the symbols used are clear every map contains a key; a list that explains what the symbols stand for. Boundary Lines: Compass Rose: Most maps feature and compass rose, a marker that indicates directions. The four Cardinal directions— north, south, east, and west—are usually indicated with arrows of points of a star. The intermediate directions—northeast, northwest, southeast, southwest—may also be shown, usually with smaller arrows or star points. Sometimes a compass rose may point in only one direction because the other directions can be determined in relation to the given direction. The compass rose on this map indicates all Cardinal directions. Cities: Represented by dots. Relative sizes of cities can be used by using dots of different size. Scale Bar: Shows the relationship between map measurements and actual distances. Capitals: Using Scale: All maps are drawn to a certain scale. ___________________ is a consistent, proportional relationship between the measurement shown on the map and the measurement of the earth’s surface. The scale of a map varies with the size of the area shown. Use the scale bar to find ____________ ______________ on a map. The __________ ___________ gives the relationship between map measurements and actual distances. Most scale bars are graphic representations, allowing you to use a ruler to calculate actual distances. 5 Small-Scale Maps A small-scale map can show a large area but little detail. Note that the scale bar for this map indicates that about ½ an inch is equal to 200 miles and about 300 kilometers. MEXICO Large-Scale Maps A large-scale map can show a small area on the earth’s surface with a great amount of detail. Note that map measurements correspond to much smaller distances than on a small-scale map. MEXICO CITY Absolute and Relative Location: As you learned before, a place’s ________________ __________________ is found at the precise point where one line of latitude crosses a line of longitude. Another way that people indicate location is by relative location. You may be told, for example, to look for a street that is “two blocks north: of another street. _________________ ________________ is the location of one place in relation to another place. To find relative location, find a _______________ _____________—a location you already know—on a map. Then look in the appropriate direction for the new location. For example, locate Houston (your reference point) on this map. The relative location of Dallas can be described as northwest of Houston and Galveston can be described as southeast of Houston. 6 Types of Maps Maps are prepared for many uses. The use for which a map is intended determines the kinds of information it contains. Learning to recognize a map’s purpose will help you make the best use of its content. General Purpose Maps: Used for ______________________, _______________-__, and __________________. There are 2 main types: Physical Map Shows location and the topography, or shape, or the earth’s physical features. Physical maps use colors or patterns to indicate relief—the difference in elevation, or height, of landforms. Some physical maps have contour lines that connect all points of land of equal elevation. Physical maps may show mountains as barriers to transportation. Rivers and streams may be shown as routes into the interior of a country. These physical features often help to explain the historical development of a country. Political Map 7 Special-Purpose Maps: Maps that emphasize a _______ __________ or a particular kind of ________________ about an area are called special-purpose maps. There are many kinds of special-purpose maps, each designed to serve a different need: relief maps, climate maps, population density maps, vegetation maps, elevation profiles, economic activity maps, and cartograms. 8 Graphs, Charts, & Diagrams In addition to globes and maps, geographers use other visual representations to display and interpret dat. Graphs, charts, and diagrams provide valuable information in forms that are well organized and easy to read. 9 Graphs: A _______________ is a visual representation of information. There are many kinds of graphs, each suitable for certain purposes. Most graphs show two sets of ______________, one displayed along the vertical axis and the other displayed along the horizontal axis. Labels on these axes identify the data being displayed. Line Graph: Shows change in two variables or changing sets of circumstances over periods of time. To analyze data on a line graph, study the changes and trends as shown by the line. Then draw conclusions based on the information. This line graph shows Unit Production of 2004. The vertical axis lists units and the horizontal axis indicates the month. Bar Graph: Shows comparisons. To analyze a bar graph, note the differences in quantities. Then make generalizations or draw conclusions based on the data. This bar graph shows Birthdays of Students by Month. The vertical axis shows the number of students and the horizontal axis indicates the month. Circle Graph: Also called a pie chart, shows the relationship of parts to a whole. Percentages are indicated by relative size and sometimes by color. To analyze a circle graph, study the relationships of areas to one another and to the whole. This circle graph shows the attendance rates of the Central Middle School Fall Festival by grade and gender. 10 Charts and Tables: Data are arranged in columns and rows in a chart or table. Charts and tables display facts in an organized manner and make ______________________ easy. To find key information in a chart or table look for the intersections of columns and rows. The table below displays information about the major rivers of the world: volume of water runoff, watershed population, and watershed land area. Diagrams: A diagram is a drawing that shows what something is or how something is done. Many diagrams feature several drawings or sections that show the ___________________________ _________________________________. The diagram below shows the phases of the moon. 11
