| map projections | ways of showing a round earth on a flat piece of paper |
| cylindrical projection | latitude and longitude are at right angles; distorts high latitudes |
| mercator projection | common type of cylindrical projection showing the entire world |
| planar projection | drawn as if a piece of paper was laid on one point of the Earth's surface; distorts direction and distance |
| conic projection | made as if a paper wrapped up into a cone shape was placed on the Earth's surface; good for showing a small area |
| map scale | shows the relationship of the distance on a map to the distance on the real Earth |
| verbal scale | written as if you read it out loud |
| graphic scale | a drawing used to show the scale of a map |
| representative fraction | shows equivalent number on units on the map to units on the real earth |
| latitude | East-West lines that measure North and South of the Equator |
| longitude | North-South lines that measure East and West of the Prime Meridian |
| international date line | 180 degrees longitude |
| Prime Meridian | was chosen to go through Greenwich England |
| topographic maps | maps that show the elevation of three dimensional landforms of the earth's surface by using contour lines |
| contour lines | lines that connect points of equal elevation above sea level and show the shape of the land |
| index contours | to make the map easier to read, every fifth contour line is darkened or labeled |
| steepness | the closer together the contour lines, the steeper the slope |
