| The shortest distance between any two points on the Earth. | great circle routes |
| How cartographers turn the round Earth into a flat map. | map projection |
| A map that shows the Earth centered in such a way that a straight line coming from the center to any other point represents the shortest distance. | planar projection |
| Why all maps are to some degree inaccurate. | distortion |
| A map that is based on the projection of the globe onto a cylinder. | cylindrical projection |
| A map that is comes from projecting a part of the globe onto a cone shape. | conic projection |
| A map that shows the true size and shape of Earth's landmasses but distorts distances. | Interrupted projection |
| Common map projection that greatly distorts size and distances of areas further from the Equator. | Mercator projection |
| Also known as parallels. | latitude |
| Also known as meridians. | Longitude |

| Maps that emphasize natural features such as lakes, rivers, landforms, etc. | physical maps |
| Maps that emphasize human-made features such as countries, cities, etc. | political maps |
| Maps created to show a specific kind of information. | thematic maps |
| maps that use dots to show the distribution of a particular phenomenon. | dot maps |
| Maps that use lines to connect points of equal value. | isoline maps |
| Maps that use color to show number values of any given phenomenon within a predefined area (counties, states, countries, etc.) | choropleth maps |
| Maps that use arrows to show movement over time. | flow-line maps |
| Maps that use circles of varying sizes to the number of a particular phenomenon within an area. | graduated circle maps |
| The network of satellites and receivers that pinpoint users' exact locations on the surface of the Earth. | GPS |
| Computer programs that store and organize data, create maps, and predict future trends based on past data. | GIS |
