Watershed and Water Table

A region or area that drains ultimately to a particular watercourse or body of water is a__________?

• Area of saturation
• Water table
• Watershed
• Porosity

Water held underground in the soil; may be a source of drinking water in springs and wells.

• Ground water
• Surface water
• Porosity
• Permeability

Which image has a higher porosity?

• A
• B

Which of the following does not affect permeability?

• the amount of space between particles
• how much rainfall falls in a year
• the size of the particles that make up the ground
• how much the particles are able to absorb

Which is an UNTRUE statement about the water table?

• flooding is more likely when it is high
• wells may run dry when it is low
• water tables are always at the same height
• lakes are formed where the water table meets the surface

A large oil truck overturns and spills its contents in the location marked by the star. Which watershed(s) would be affected by this spill?

• 12
• 14
• 18
• All of the above

What conditions will increase the amount of runoff and flooding in an area?

• drought conditions
• the water table being low
• soil types that have high permeability
• when the ground is already saturated

The amount of space between particles.

• Runoff
• Surface water
• Permeability
• Porosity/Pore space

How well water flows through a substrate.

• Permeability
• Porosity/Pore space
• Water table
• Run off
