| Question | Answer |
|---|---|
| The point on Earth’s surface having zero degrees latitude and zero degrees longitude would be located | where the equator crosses the prime meridian. |
| A topographic map differs from a road map in that the topographic map shows | elevation, relief, and slope. |
| Elevation on a topographic map are shown using symbols called | contour lines. |
| What kind of slope do closely spaced contour lines indicate? | steep |
| To find the latitude, longitude, and elevation of points on Earth’s surface, the Global Positioning System uses | signals from a network of satellites. |
| It would be easy to walk up a slope represented by contour lines that | are far apart. |
| The contour lines that represent the top of a hill form | a closed loop. |
| A map projection in which the lines of latitude and longitude are all straight, parallel lines that form a rectangle is the | Mercator projection. |
| The distance in degrees east or west of the prime meridian is called | longitude. |
| On a Mercator projection, Greenland appears larger than South America because | Mercator projections enlarge areas near the poles. |
| What type of map shows changes in elevation on Earth’s surface? | topographic map |
| What is the reference point for lines of latitude? | the equator |
| Do lines of latitude run from north to south, meeting at the poles? | No, lines of latitude never cross, but they are measured in degrees North and South. |
