4. A line that connects points of equal elevation on a map.
5. The relationship between the measurements on a model, map, or diagram and the actual measurement or distance.
8. An area of the shoreline that is made up of deposited sediment.
10. A map that shows the surface features of Earth.
12. On a map, a darker, heavier contour line that is usually every fifth line and that indicates a change in elevation.
13. The rapid mass movement of rock down a steep slope or cliff.
14. The size and shape of the land surface features of a region, including its relief.
15. A long ridge of sand or narrow island that lies parallel to the shore.
17. A measure of the slant of a line; the ratio of rise over run.
21. The process of gathering and analyzing information about an object without physically being in touch with the object.
23. Fine-grained sediments of quartz, feldspar, hornblende, mica, and clay deposited by the wind.
24. The slow downhill movement of weathered rock material.
25. A low ridge of sand deposited along the shore of a lake or sea.
26. The difference between the highest and lowest elevations in a given area; the variations in elevation of a land surface.
28. A network satellites that orbit Earth to measure positions on Earth’s surface.
29. The difference in elevation between one contour line and the next.

1. An automated system for capturing, storing, retrieving, analyzing, manipulating, and displaying geographic data.
2. The process in which material is laid down
3. A fan-shaped mass of material deposited by a stream when the slope of the land decreases sharply.
6. A large mass of ice that exists year-round and moves over land.
7. The water that is beneath Earth’s surface.
9. A mass of material deposited in a triangular or fan shape at the mouth of a river or stream.
11. The flow of a mass of mud or rock and soil mixed with a large amount of water.
16. A mound of wind-deposited sand that moves as a result of the action of wind.
18. The sudden movement of rock and soil down a slope.
19. An area along a river that forms from sediments deposited when the river overflows its banks
20. The boundary between land and a body of water.
22. The rock material carried and deposited by glaciers.
27. The process by which wind, water, ice or gravity transports soil and sediment from one location to another
