What is the water that fills the cracks and spaces in underground soil and rock layers called?

An underground layer of rock or sediment that holds water?

• Reservoir
• Aquifer
• Groundwater
• Watershed

The land area that supplies water to a river system is called a

• water table
• trailer
• house
• watershed

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

• Permeable
• Impermeable

Water from precipitation soaks down through permeable rock and soil layers.  These layers contain air as well as water, so they are not saturated, or filled, with water.  This top layer is thus called the 

• unsaturated zone
• saturated zone

At some depth, the water reaches a level where the pores in the ground are saturated with water, called the 

• saturated zone
• unsaturated zone

What is the name of the area of groundwater where it is saturated?

• Zone of Saturation
• Zone of Aeration
• Water Table

The name of the area that is the upper level of the zone of saturation:

• Zone of Saturation
• Zone of Aeration
