Terms | Definitions |
|---|---|
 Topography | the shape of the land |
| Elevation | the height above sea level of a point on earth's surface |
| Relief | the difference in elevation between the highest and lowest parts of an area |
| Landform | a feature of topography formed by the processes that shape Earth's surface |
| Plain | a landform made up of nearly flat or gently rolling land with low relief |
| Mountain | a landform with high elevation and high relief |
| Plateau | a landform that has high elevation and a more or less level surface |
| Landform region | a large area of land where the topography is made up mainly of one type of landform |
| Map | a flat model of all or part of Earth's surface as seen from above |
| Scale | relates distance on a map to a distance on Earth's surface |
| Globe | a sphere that represents Earth's entire surface |
| Key/Lengend | a list of all the symbols used on the map with an explanation of their meaning |
| Degree | 1/360 of the distance around a circle |
| Equator | an imaginary line that circles Earth halfway between the North and South poles |
| Hemisphere | 1/2 of the sphere that makes up Earth's surface. |
| Prime Meridian | another iaginary line that makes a half circle from the North Pole to the South Pole |
| Latitude | the distance in degrees north or south of the equator |
| Longitude | the distance in east or west of the prime meridian |
| Map Projection | a framework of lines that helps in transferring points on Earth's three-dimensional surface onto a flat map. |
| Topographic Map | a map that shows the surface features of an area |
| Contour line | a line on a topographic map, a line that connects points of equal elevation |
| Contour Interval | the difference in elevation from one contour line to the next |
| Index Contour | on a topographic map, a heavier contour line that is labeled with elevation of that contour line in round units |
