Permeable and Impermeable

Define permeability

• Water

• Nothing

• Percent of volume of open spaces in rock or sediment

• Ability rock/sediment fluids pass through open spaces/pores

How does porosity affect permeability?

• Soil has to be porous to be permeable

• No effect

• Some kinds of soil can be porous but NOT permeable

• Soil has to be permeable to be porous

What affect does particle size have on permeability

• No effect

• The larger the particles the lower the permeability

• The larger the particles the higher the permeability

• The smaller the particles the higher the permeability

Which sample is MOST permeable?

• round

• flat

• oval

Which sample is LEAST permeable?

• round

• oval

• flat

Which of the following statements is the definition of permeability?

• the amount of air space between sediments

• the ability of water to flow through sediments

• the density of sediments

• the infiltration rate

Water moves very slowly through clay. Which statement about clay must be true?

• clay has large pore spaces

• clay has round particles

• clay is impermeable

What is the primary difference between permeable and impermeable materials?

• Permeable materials allow fluids to pass through, while impermeable materials do not.

• Permeable materials are always solid, while impermeable materials are liquid.

• Permeable materials are found in nature, while impermeable materials are man-made.

• Permeable materials are heavier than impermeable materials.

Which of the following is an example of a permeable material?

• Granite

• Clay

• Sand

• Plastic

In an experiment, water is poured over a layer of sand and a layer of clay. What is the expected observation?

• Water passes quickly through both layers.

• Water passes quickly through sand but slowly through clay.

• Water passes quickly through clay but slowly through sand.

• Water does not pass through either layer.
