• surface water
• water table

What is a watershed?

• Land that collects and channels water froma small body of water to a larger body of water
• the shape of the land determined by elevation
• A natural stream of water of considerable  volume
• a river and all its tributaries

An area of permeable layer of rock or soil that holds a large amount of water in the saturated zone is called what?

• Aquifer
• Spring
• Well
• Reservoir

Water stored  in cracks and pores below the Earth's surface is called:

• Groundwater
• Bogs
• Water in the ground
• surface water

A divide is 

• well in which water rises because of pressure
• Forms the boundaries of a watershed
• type of hot spring from which the water periodically erupts
• place where groundwater bubbles or flows out of cracks in the rock

What is the top of the water-filled spaces  (saturated zone) in the ground called?

• Groundwater
• Reservoir
• Water Table

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

• Permeable
• Impermeable
• Solid
• Soft

Pollution has ___________

• a negative human impact
• positive human impact
• humans have no impact 

Water from precipitation soaks down through permeable rock and soil layers.  These layers contain water.  This bottom layer is the 

• unsaturated zone
• saturated zone
• in the zone, auto zone
