Groundwater

The area where water fills all of the pore space in sediment and rock is called 

• belt of soil moisture
• zone of aeration
• zone of saturation
• water table

The upper limit of the zone of saturation is called 

• belt of soil moisture
• zone of aeration
• zone of saturation
• water table

A permeable layer of sediment or rock that allows water to flow through is called

• aquitard
• aquifer

For an artesian well to form, the aquitard must be trapped between two aquifers

• true
• false

Which acid dissolves limestone beneath the surface to form a cavern?

• hydrochloric
• carbonic
• phosphoric

Wetlands are important to humans because:

• they provide flood protection
• they improve water quality
• they act as a filter
• all of the above

A hole dug into an aquifer to reach groundwater is called... 

• an aquitard/aquiclude
• a well
• a recharge zone
• a water table

The ___________________ the grain size, the faster the water will move through the soil.

• more mixed
• smaller
• larger

This type of rock allows water to flow through it and recharge an aquifer

• impermeable
• permeable
• water table
• non-porous

 96.5% of all water can be found...

• in oceans
• in glaciers
• in the ground
• in the atmosphere
