Groundwater, Permeability & Porosity

The ___________________ the grain size, the faster the water will move through the soil.

• more mixed
• smaller
• larger

Sand sediments are usually more permeable than silt sediments because sand grains are...

• larger
• smoother
• rounder
• more soluble

What is the relationship between soil type/particle size and permiability (as shown by the bar graph below)?

• The larger the particle size, the slower the permeability rate

• The smaller the particle size, the faster the permeability rate

• There is no relationship between particle size and permeability

• The larger the particle size, the faster the permeability rate

Impermeable materials...

• have an abundance of pores.
• let water in.
• have little to no pores.

the measure of the storage space available in an aquifer.

• aquifer
• permeability
• porosity
• divide

The measure of how easily water can flow through an aquifer. 

• porosity
• permeability
• gradient
• divide

Porosity refers to...

• the shape of the particles
• The sorting of the particles
• % of pore space in a material
• % of cement in a material

Porosity is dependent on all of the following EXCEPT...

• Particle shape
• Amount of cement
• Sorting
• Hardness

Which of the following has the lowest porosity?

• Clay
• Silt
• Gravel
• Sand

The ___________________ the grain size, the faster the water will move through the soil.

• more mixed
• smaller
• larger
