Groundwater and Aquifer Exam

In the diagram, letter A best represents:

• Runoff

• Watershed

• Water Table

• Confining Layer

During the process of infiltration, water seeps through the ground and into an aquifer. Which of the following terms best describes this process?

• Recharge

• Discharge

• Depletion

• Surcharge

Which of the layers is composed of impermeable material?

• Layer B: the unconfined aquifer

• Layer C: the unconfined aquifer

• Layer C: the confining layer

• Layer D: the unconfined aquifer

What is the relationship between groundwater and surface water?

• Surface water percolates (moves) through the soil to form groundwater.
• There is no relationship between surface and groundwater.
• Groundwater filters through the soil to form surface water.
• Surface water is found in lakes directly above underground water sources.

What are the spaces called through which water moves through soil?

• holes

• tubules

• tunnels

• pores

Out of all the water on Earth, how much is freshwater?

• 100%

• 70%

• 30%

• 3%

If a well is over-pumped... what could happen?

• there will be more groundwater

• less groundwater + aquifers will dry out

• the water table does not change

What is the source of groundwater?

• rain, snow, melted glaciers
• ocean water
• icebergs
• water from fossilized animals
