  • What is the water table?
  • How does the use of water by humans affect the water table?
The water table is high under hills and low under valleys.Lakes and streams are surface expressions of the water table.The water table can be lowered if too much groundwater is pumped out.

  • Which of the following statements about the water table is true?
streams that drop below the ground surface, flowing into open joints or caverns
  • hydraulic gradient
  • springs
  • disappearing stream
  • Zone of Saturation
715 feet above sea level
  • Karst topography can be identified even when looking at a topographic map. Which of the following features would show up easily on a topographic map, indicating a karst landscape?

  • How would the water table be affected if Earth were made up of uniform, permeable material?
  • (A) __________ will form when high-capacity wells pump too much water from the subsurface, resulting in a dimple in the water table.
Gaps between pieces of sediment and fractures/cracks in rocks. Allows solid rock and soil to hold water.
