| Question | Answer |
|---|---|
| Topograph | the shape of land determined by elevation, relief, and landforms |
| elevation | height above sea level |
| relief | the difference in elevation between the highest and lowest parts of an area |
| landforms | a feature of topography formed by the processes that shape Earth's surface. |
| mountain ranges | a group of mountains that are closely related in shape, structure, area, and age |
| plateau | a large landform that has high elevation and a more or less level surface |
| landform regions | 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 surfaces seen from above |
| map protection | 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 the 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 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 meridian | the line that makes 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 meridian |
| surveying | the process of gathering data for a map by using instruments and the principles of geometry to determine distance and elevations |
| digitizing | converting information to numbers for use by a computer |
| pixel | one bit of a digitized image, often appearing as a small square or dot |
| aerial photograph | a photograph taken by cameras mounted in airplanes. |
| satellite image | a picture of the land surface based on computer data collected from satellites |
| Global positioning system | a navigation system that uses satellite signals to locate a radio receiver on Earth's surface. |
| Geographic Information 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 contour line to the next. |
| index contour | On topographic map, a heavier contour line that is labeled with elevation of that contour line. |
