What is permeability?
The ability for water to pass through a material
(Or something like this)
What is porosity
How much space there is available for water to move
Water that flows down land
Runoff
Explain how runoff can pollute water supplies
ANSWERS MIGHT VARY
Pollution that CAN be traced back to a single person or place
Point Source
Which will water flow through fastest?
Sand, silt, clay, pebbles
Pebbles
A soil sample with a high percentage of open space between grains must have ....
High Porosity
Water that gathers in pond or lake or river
Collection
The area below the water table
Saturated Zone
Pollution that CANNOT be traced back to a single person or place
Non-Point Source
What type of material lets water through the slowest?
Clay
When comparing pebbles, sand and clay, which would have the higher porosity?
Pebbles
Water comes down to Earth from the clouds
Precipitation
Explain the difference between porosity and Permeability
Porosity is how much space there is, permeability is how easily the water can move through
