  1. 1. Geography By Ashley Dale
  2. 2. What is a Map? <ul><li>A map is a representation, usually on a flat surface, of the features of an area of the earth or a portion of the heavens, showing them in their respective forms, sizes, and relationships according to some convention of representation. </li></ul>
  3. 3. Now what does that mean? <ul><li>A map is a representation, </li></ul><ul><li>A map is a drawing or model </li></ul><ul><li>usually on a flat surface, </li></ul><ul><li>of a round Earth on a flat surface, </li></ul><ul><li>of the features of an area of the earth </li></ul><ul><li>that shows the landforms (mountains, rivers, etc.) </li></ul><ul><li>or a portion of the heavens, </li></ul><ul><li>or part of the sky in a particular region, </li></ul><ul><li>showing them in their respective forms, sizes, and relationships </li></ul><ul><li>drawn to scale </li></ul><ul><li>according to some convention of representation. </li></ul><ul><li>using an accepted form of drawing or model. </li></ul>
  4. 4. Why Maps Are Useful… <ul><li>They show people where things are. </li></ul><ul><li>Can include information on population, elevation, resources, etc. </li></ul><ul><li>They show you how to get places you want to go. </li></ul>
  5. 5. The World Political <ul><li>Political maps show how people have divided places on the Earth into countries, states, cities and other units for the purpose of governing them. </li></ul>
  6. 6. The World Physical <ul><li>Physical maps show what the surface of the Earth looks like. </li></ul>
  7. 7. Oceans of the World <ul><li>The world has four major oceans. </li></ul><ul><li>Atlantic </li></ul><ul><li>Pacific </li></ul><ul><li>Arctic </li></ul><ul><li>Indian </li></ul>Pacific ocean Atlantic ocean Arctic ocean Indian ocean
  8. 8. Global Climates <ul><li>Students generally associate Arctic and Antarctic with cold weather, so students could make the observation that the climate at the poles is cold. This map shows the general climate regions of the world. </li></ul>
  9. 9. World Religions <ul><li>Religious beliefs help define a people’s culture, so to understand a people, it is important to consider what religions influence that group. </li></ul>
  10. 10. Compass <ul><li>A compass is a tool that helps the user know what direction one is headed. </li></ul><ul><li>On a map, a compass or a compass rose helps the user locate these directions. </li></ul>
  11. 11. Compass Rose <ul><li>The needle on a compass is magnetized to point to the earth's north magnetic pole. Thus with a compass, a person can roughly tell which direction they are headed. </li></ul><ul><li>There are four major or cardinal directions on a compass- north, south, east & west. In between are the directions northeast, northwest, southeast, southwest. </li></ul>
  12. 12. Directions <ul><li>The cardinal directions are north, south, east, and west. </li></ul><ul><li>The intermediate directions are northeast, southeast, southwest and northwest. </li></ul><ul><li>They help describe the location of places in relation to other places. </li></ul>
  13. 13. Scale <ul><li>Maps are made to scale; that is, there is a direct connection between a unit of measurement on the map and the actual distance. </li></ul><ul><li>For example, each inch on the map represents one mile on Earth. So, a map of a town would show a mile-long strip of fast food joints and auto dealers in one inch. </li></ul>
  14. 14. Time Zones <ul><li>The Earth is divided into 24 time zones, corresponding to 24 hours in a day. </li></ul><ul><li>As the earth rotates, the sun shines in different areas, moving from east to west during the course of a day. </li></ul><ul><li>Places that have the same longitude will be in the same time zone. </li></ul>
  15. 15. Time Zones of United States
  16. 16. Map Legend <ul><li>. </li></ul>The legend is the key to unlocking the secrets of a map. Objects or colors in the legend represent something on the map. .
  17. 17. Latitude and Longitude <ul><li>The earth is divided into lots of lines called latitude and longitude. </li></ul>
  18. 18. Longitude and Latitude Line of longitude only Equator Added Lines of latitude added
  19. 19. The Difference <ul><li>Orange cut through Orange cut </li></ul><ul><li>lines of longitude through lines of </li></ul><ul><li> latitude. </li></ul>
  20. 20. Angle of the Sun The angle of elevation of the sun varies with latitude. The sun is higher in the sky at places closer to the equator (‘lower latitudes’).
  21. 21. Angle of Latitude
  22. 22. Equator <ul><li>The equator is 0 degree latitude. </li></ul><ul><li>It is an imaginary belt that runs halfway point between the North Pole and the South Pole. </li></ul>Equator
  23. 23. Prime Meridian <ul><li>The prime meridian </li></ul><ul><li>is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica. </li></ul>P R I M E M E R I D I A N
  24. 24. Hemispheres By using the equator and prime meridian, we can divide the world into four hemispheres, north, south, east, and west.
