|---|---|
| maps that show the features of the earth's surface | topographic map |
| surface features of the earth | topography |
| height above sea level of various island locations | elevation |
| point midway between the highest and lowest tides | mean sea level |
| sea level is measured as | 0(where water meets land) |
| show changes in elevation on the map | contour lines |
| each contour line connects... | each point on the map with the same elevation |
| difference in elevation between 1 contour line and the next | contour interval |
| contour interval in math is | range |
| USGS stands for | United states geological survey |
| ratio to determine true distances compared to map distances | scale |
| topographic sheets = | quadrangle |
| every fifth contour line which is printed darker than thhe others | index contour |
| x marks__________on a map | highest elevation |
| the x on a map is called | benchmark |
| Contour lines spaced widely apart indicate | gradual elevation where land is reletively flat |
| Closed spaced contour lines indicate | steep slope |
| Contour lines almost touching indicate | a cliff |
| Contour lines that bend to form a "v" shape indicate | a valley |
