Geography Skills - Thematic Maps & Climate

  1. 1. Created by tbonnar.
  2. 2.  A map is an image that represents an area of the earth’s surface, usually from above.
  3. 3.  A map can provide different information such as place names, land features, elevation, and political boundaries.
  4. 4.  North is usually at the top of the map, check the compass rose to see if it has been repositioned in a different direction.
  5. 5.  Physical maps indicate natural features such as mountains, deserts, rivers and lakes.
  6. 6.  Political maps focus on the division of the earth’s surface into different countries, states or provinces.
  7. 7.  Most maps in this atlas will show physical features as well as country borders, cities, and towns.
  8. 8.  Today, scientists can make more accurate maps of the world than ever before. They can use information from satellites that orbit the earth.
  9. 9.  A thematic map is one that focuses on a particular main idea (or theme). These might include:  Climate  Vegetation  Economy  Population  Language
  10. 10.  Map legends are very important for all types of maps, but perhaps especially so for thematic maps. Legends can include:  Symbols  Elevation  Scale  Colour Keys
  11. 11.  Maps often use symbols instead of words to label real-life features and make maps clearer.
  12. 12.  Symbols can be small pictures, letters, lines or coloured areas.
  13. 13.  Each symbol is placed in a key or legend next to the map. The key explains what each symbol means.
  14. 14.  Climate Maps are a type of Thematic Map. They present information about climate such as:  Temperature  Precipitation  Sunshine Hours  Growing Season  Climate Regions  Environmental Concerns
  15. 15.  Climate is the overall weather pattern of a region. The two major aspects of climate are temperature and precipitation.
  16. 16.  A Climate Graph shows:  A title  Precipitation bars in blue  A temperature line in red  Months of the year  Usually the Total Annual Precipitation  Sometimes the growing season at 6°C Interactive Climate Graphs
  17. 17.  Revolution of the earth  Rotation of the earth – causes seasons – causes day and night
  18. 18.  latitude – proximity to  altitude (elevation) – the equator or to the temperature decreases poles ex. high latitude 1 C for every increase = lower temperatures of 165 metres
  19. 19.  wind – wind can lower or raise temperature depending on where the wind comes from large bodies of water – water’s temperature changes more slowly than land’s temperature; therefore the temperature near large bodies of water will be more moderate
  20. 20.  ocean currents – make the water cold or warm and thus affect the land
  21. 21.  pollution (man-made or natural)  gases in the atmosphere trap heat  forest fires and volcanoes can also affect temperature
  22. 22.  winds – will bring precipitation to an area large water bodies – will usually increase precipitation in that area
  23. 23.  air pressure – differences in air pressure cause precipitation to fall
  24. 24.  temperature – interaction between warm and cold air causes precipitation
  25. 25.  physiography – the presence of physical features such as mountains or deserts
  26. 26.  Orographic – caused by mountains, as in Greater Vancouver
  27. 27.  Convectional – thunderstorms, caused by the rising of hot air
  28. 28.  Cyclonic – the most common type, caused by differences in air pressure
