| Question | Answer |
|---|---|
| topography | The shape of the land determined by elevation, relief, and land forms |
| elevation | Height above sea level |
| 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 land form made up of a flat or gently rolling land with low relief |
| mountain | A land form with high elevation and high relief |
| mountain range | A group of mountains that are closely related in shape, structure, area, and age. |
| plateau | A large land form 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 |
| globe | A sphere that represents Earth's entire surface |
| map | A flat model of all or part of Earth's surface as seen from above |
| map projection | A framework of lines that helps to transfer points on Earth's surface onto a flat map |
| symbol | On a map, a picture used by mapmakers to stand for features on Earth's surface. |
| key | A list of the symbols used on a map and their meanings |
| scale | Used to relate distance on a map or globe to distance on Earth's Surface |
| degree | A unit used to measure distances around a circle. One degree equals 1/360 of a full circle. |
| equator | An imaginary line that circles Earth halfway between the North and South poles. |
| hemisphere | One half of the sphere that makes up earth's surface |
| prime median | The line that makes a half circle from the North Pole to the South Pole and that passes through Greenwich, England |
| latitude | The distance in degrees north or south of the equator |
| longitude | The distance in degrees east or west of the prime median |
| surveying | The process of gathering data for a map by using instruments and the principles of geometry to determine distance and elevtaion |
| digitizing | Converting information to numbers for use by a computer |
| pixel | One bit of a digitized image, often appearing as a small square or a dot. |
| aerial photograph | A photograph taken by cameras mounted in airplanes |
| satellite image | A picture of land surface based on computer data collected from satellites |
| global positioning system | A system of computer hardware and software used to produce interactive maps |
| topographic map | A map that shows the surface features of an area |
| contour line | A line on a topographic map 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 on that contour line. |
