• Groundwater
• Water Table
• Precipitation
• Snow

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

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

• Zone of Saturation
• Zone of Aeration
• Water Table

• Zone of Saturation
• Zone of Aeration
• Water Table

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

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

What is a place where groundwater seeps out of the ground called?

• Well
• Reservoir
• Aquifer
• Spring

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

A well in which groundwater rises because of pressure is called a(n)

• spring well
