Water Systems

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

Why is gravity a factor in watersheds? 

• it causes the water to flow away from a watershed
• it causes the water to flow towards a watershed

Define tributaries

• small rivers or streams that flow into a large river or stream
• a natural stream of water of considerable volume
• precipitation that flows over the land to streams
• a continuous ridge that separates a watershed

What is a divide?

• a natural stream of water of considerable volume
• a continuous ridge that separates one watershed from another
• small rivers or streams that flow into a larger river or stream
• a body of fresh water found in low lying areas

Water stored below the Earth's surface is called:

• Groundwater
• Bogs
• Water in the ground

What is a hole dug below the water table that water seeps into?

• Well
• Spring
• Aquifer
• Reservoir

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
