Science Definitions

2. The slow downhill movement of weathered rock material.
5. The flow of mass of mud or rock and soil mixed with a large amount of water.
7. The size and shape of the land surface feature of a region, including its relief.
9. A line that connects points of equal elevations on a map.
11. The sudden movement of rock and soil down a slope.
12. A low ridge of sand deposited along the shore of a lake or sea.
14. An area of the shoreline that is made up of deposited sediment.
18. An area along a river that forms from sediments deposited when the river overflows its banks.
20. A network of satellites that orbit Earth to measure on Earth’s surface.
21. The difference between the highest and lowest elevations in a given area; the variations in elevation of a land surface.
22. A mass of material deposited in a triangular or fan-shaped at the mouth of a river or stream.
24. An automated system for capturing, storing, retrieving, analyzing, manipulating, and displaying geographic data.
26. The rock material carried and deposited by glaciers.
27. The water that is beneath Earth’s surface.
28. The process of gathering and analyzing information about an object without physically benign in touch with the object.

1. The process in which material is laid down.
3. The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
4. The boundary between land and a body of water.
6. A map that shows the surface features of Earth.
8. A fan-shaped mass of material deposited by a stream when the slope of the land decreases sharply.
10. Along a ridge of sand or a narrow island that lies parallel to the shore.
13. The rapid mass movement of rock down a steep slope or cliff.
15. Fine-grained sediments of quartz feldspar, hornblende, mica, and clay deposited by the wind.
16. A measure of the slant of a line; the ratio of rise over run.
17. A mound of wind-deposited sand that moves as a result of the wind.
19. On a map, a darker, heavier contour line that is usually every fifth line and that indicates a change in elevation.
23. The difference in elevation between one contour line and the next.
25. The size and shape of the land surface feature of a region, including its relief.
27. A large mass of ice that moves year-round and moves over land.
29. The relationship between the measurements on a model, map, or diagram and the actual measurement or distance.
