Is it possible for a material to be highly porous but impermeable (not
permeable)?
Question 8
8.
How can a solid rock become permeable?
Question 9
9.
Look at the image above. It shows the amount of time it takes for water to pass
through each of the substances. Why does it take longer for water to move
through clay than it does gravel?
Question 10
10.
Look at the image above. Which one of the 4 tubes has a higher permeability? How
do you know?
Porosity is
the capacity of a rock to transmit fluid.
the ability of a rock to prevent water from entering it.
the percentage of a rock's volume that is open space.
none of the above

Which will have a higher infiltration rate?
Clay
Pebbles
Sand
When rainfall occurs, the rainwater will most likely become surface runoff if
the land surface is
Impermeable
Nearly flat
sandy
covered with grass
Water will enter the soil if the ground surface is
impermeable and unsaturated
impermeable and saturated
permeable and saturated
permeable and unsaturated
Which condition is most likely to cause surface runoff
during a rainstorm?
The permeability of the soil is greater than the rate ofrainfall
The surface soil is saturated.
The surface slope allows for maximum infiltration.
The porosity of the soil is greater than the amount ofrainfall.
