| map projection | a method of transferring to paper the points and lines on a globe's surface |
| Mercator projection | a map-projection method using parallel longitude lines; continent shapes are accurate, but their areas are distorted |
| Robinson projection | a map-projection method using curved longitude lines; continent shapes and land areas are accurate with little distortion |
| conic projection | a map projection made by projecting points and lines from a globe onto a cone; it produces accurate maps of areas smaller than the whole Earth, such as a nation or state |
| topographic map | a map that uses contour lines to show changes in elevation at Earth's surface; shows natural features such as lakes and cultural features such as cities and dams |
| contour line | a line on a topographic map that connects points of equal elevation |
| contour interval | the difference in elevation between two side-by-side contour lines on a topographic map |
| map legend | the key on most maps that is used to explain what the symbols on the map mean |
| map scale | the relationship between distances drawn on a map and actual distances on Earth's surface |
