Water Review- Environmental Science

What do we call the land area that supplies water to a river system?

• runoff
• recharge
• watershed
• valley

What is an underground layer of rock or soil filled with water called?

• Aquifer
• Spring
• Well
• Reservoir

What is the top of the water-filled spaces in the ground called?

• Groundwater
• Reservoir
• Water Table
• Well

What do we call water that flows over the ground surface rather than soaking in?

• runoff
• discharge
• recharge
• tributary

An aquifer is a(n)

• well in which water rises because of pressure
• underground layer of rock or sediment that holds water
• type of hot spring from which the water periodically erupts
• place where groundwater bubbles or flows out of cracks in the rock

Which types of aquifers are in the most danger of becoming contaminated by pollutants?

• aquifers confined by a permeable layer
• unconfined aquifers

Because they have large connected pores, materials such as sand and gravel allow water to pass through.  This material is

• Permeable
• Impermeable

Any underground layer of permeable rock or sediment that holds water and allows it to flow is called an 

• Acquifer
• Ocean
• Water table
• Water shed

The top of the groundwater’s zone of saturation - E

• Zone of Aeration
• Aquifer
• Surface water
• Water table

An area where water (from precipitation or a stream) seeps into an aquifer, adding to the groundwater, is called a

• water table
• recharge area
• discharge area
• runoff
