shale conglomerate


limestone sandstone





15. _____ is sometimes known as "volcanic glass."

16. When the plant cover is removed from an area, making the bare soil easily removable by wind and rain, _____ is said to have occurred.


desertification soil depletion


salinization none of these answers is correct








18. This problem occurs in desert areas when the evaporated rain water leaves behind a layer of minerals, making crop growth nearly impossible.


desertification soil depletion


salinization none of these answers is correct








19. The average change in elevation over a given distance is known as _____.


contour elevation


average slope gradient





20. Which is NOT a method of remote sensing?


Landsat imaging ground surveying


imaging radar photogrammetry





23. The distance between two contour lines indicates:


how far apart the areas are the steepness of an area


the elevation of the area the composition of the land area





26. In the water budget, what occurs when rainfall exceeds the need for moisture and the soil is saturated?


usage deficit


recharge surplus





27. Where is most of Earth's fresh water located?


icecaps and glaciers lakes and swamps


oceans and seas streams and rivers





28. The formation of a mineral deposit around a spring is LEAST likely to occur if the local groundwater:


comes from rainfall is very hot


passes through salt beds contains large quantities of gases





29. This occurs when water soaks into the ground and becomes part of the soil water supply:


recharge impermeable


geysers usage


evapotranspiration porosity


deficit hydrosphere


water table aquifer





30. This is the surface of the zone of saturation:


recharge impermeable


geysers usage


evapotranspiration porosity


deficit hydrosphere


water table aquifer
