Two Tools of GeographersTwo Tools of Geographers1. Globes (more accurate)
2. Maps
- all maps distort the earth in some way
• Map projections: ways of showing the curved earth on a flat surface
• Four main map projections
1. Mercator Projection
2. Peters Projection
3. Interrupted Projection
4. Robinson Projection

Map ProjectionsMap Projections
1. Mercator Projection
- the “big box”
- accurate near the equator
- land is distorted at the poles
Map ProjectionsMap Projections
2. Peters Projection
- the rectangle
- correct areas of land and sea
- some continents appear longer than they really are
Map ProjectionsMap Projections
3. Interrupted Projection
- correct areas of land and sea
- cuts out parts of oceans
- makes measuring distance impossible
Map ProjectionsMap Projections
4. Robinson Projection- the oval; most used- correct sizes and shapes of land masses- fairly accurate distances
- Distortions occur along the edges
Types of MapsTypes of Maps
• Physical- show topography: physical features of a place or region
• Population- show how many people live in an area
• Climate- show what the typical climate is like in an area
• Political, etc.

Major LandformsMajor Landforms
• Four major landforms
1. mountains
2. hills
3. plateaus
4. plainsRivers and lakes are NOTNOT landforms! They are waterforms.
ClimateClimate
• Climate: the average weather a place has over a period of 20 to 30 years (pg. 778)
• What is the difference between climate and weather?
• How can climate affect the way we live? (think about the 3rd theme of geography- interaction)
ClimateClimate
• Factors that affect climate
- latitude (how close to equator?)
- proximity to oceans- oceans act as climate mediators
- elevation (height above sea level)
ReviewReview
• 4 Map Projections– Mercator, Peters, Interrupted, Robinson
• 3 types of maps– Physical, Population, Climate
• 4 Major Landforms– Mountains, hills, plateaus, plains
• Climate– Factors that affect climate
