Mapping Review

1. short dashed lines drawn perpendicular to an enclosed contour line which are used to indicate a depression, always point toward lower elevation
3. map that shows the different shapes and sizes of a land surface using contour lines (no space)
8. lines that pass through points on a map that have the same elevation (no space)
9. level of the surface of the sea midway between the average high and low tides, referred to as 0 feet (no space)
12. configuration of a surface and the relations among its man-made and natural features, includes landforms, elevation, latitude, longitude
13. system for the detection of objects under water and for measuring the water’s depth by emitting sound pulses
16. height above sea level
19. line located along the 180th meridian; division between calendar day

2. the measurement east and west of the Prime Meridian
4. the difference in elevation between two consecutive contour lines (no space)
5. the measurement north and south of the equator
6. meridian that runs through Greenwich, England; 0 degrees longitude(no space)
7. an explanatory accompanying a map, chart, or illustration
10. one of the 24 regions of the globe through which the same standard of time is used (no space)
11. global positioning system; radio navigation system that allows users to determine their exact location
14. line that runs between the points on a globe/map that represent the north and south poles of Earth
15. lines going from east to west across a map or globe that cross a meridian right angles
17. imaginary line around the Earth that divided the Earth into two hemispheres; located halfway between the north and south poles
18. a fixed ration between the size of a real object and the size of a model of the same object
