Maps, Landforms, And Climate

  1. 1. Maps, Landforms, and Climate Physical Geography
  2. 2. Two Tools of Geographers <ul><li>Globes (more accurate) </li></ul><ul><li>Maps </li></ul><ul><li>- all maps distort the earth in some way </li></ul>
  3. 3. <ul><li>Map projections: ways of showing the curved earth on a flat surface </li></ul><ul><li>Four main map projections </li></ul><ul><li>1. Mercator Projection </li></ul><ul><li>2. Peters Projection </li></ul><ul><li>3. Interrupted Projection </li></ul><ul><li>4. Robinson Projection </li></ul>Two Tools of Geographers
  4. 4. Map Projections <ul><li>Mercator Projection </li></ul><ul><li>- the “big box” </li></ul><ul><li>- accurate near the equator </li></ul><ul><li>- land is distorted at the poles </li></ul>
  5. 5. Map Projections <ul><li>2. Peters Projection </li></ul><ul><li>- the rectangle </li></ul><ul><li>- correct areas of land and sea </li></ul><ul><li>- some continents appear longer than they really are </li></ul>
  6. 6. Map Projections <ul><li>3. Interrupted Projection </li></ul><ul><li>- correct areas of land and sea </li></ul><ul><li>- cuts out parts of oceans </li></ul><ul><li>- makes measuring distance impossible </li></ul>
  7. 7. Map Projections <ul><li>4. Robinson Projection </li></ul><ul><li>- the oval; most used </li></ul><ul><li>- correct sizes and shapes of land masses </li></ul><ul><li>- fairly accurate distances </li></ul><ul><li>- Distortions occur along the edges </li></ul>
  8. 8. Types of Maps <ul><li>Physical - show topography : physical features of a place or region </li></ul><ul><li>Population - show how many people live in an area </li></ul><ul><li>Climate - show what the typical climate is like in an area </li></ul><ul><li>Political, etc. </li></ul>
  9. 9. <ul><li>Physical </li></ul>Types of Maps
  10. 10. <ul><li>Population </li></ul>Types of Maps
  11. 11. <ul><li>Climate </li></ul>Types of Maps
  12. 12. Major Landforms <ul><li>Four major landforms </li></ul><ul><li>1. mountains </li></ul><ul><li>2. hills </li></ul><ul><li>3. plateaus </li></ul><ul><li>4. plains </li></ul>Rivers and lakes are NOT landforms! They are waterforms .
  13. 13. Climate <ul><li>Climate : the average weather a place has over a period of 20 to 30 years (pg. 778) </li></ul><ul><ul><ul><li>What is the difference between climate and weather? </li></ul></ul></ul><ul><ul><ul><li>How can climate affect the way we live? (think about the 3 rd theme of geography- interaction ) </li></ul></ul></ul>
  14. 14. Climate <ul><li>Factors that affect climate </li></ul><ul><li>- latitude (how close to equator?) </li></ul><ul><li>- proximity to oceans </li></ul><ul><li>- oceans act as climate mediators </li></ul><ul><li>- elevation (height above sea level) </li></ul>
  15. 15. Review <ul><li>4 Map Projections </li></ul><ul><ul><li>Mercator, Peters, Interrupted, Robinson </li></ul></ul><ul><li>3 types of maps </li></ul><ul><ul><li>Physical, Population, Climate </li></ul></ul><ul><li>4 Major Landforms </li></ul><ul><ul><li>Mountains, hills, plateaus, plains </li></ul></ul><ul><li>Climate </li></ul><ul><ul><li>Factors that affect climate </li></ul></ul>
