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

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

let water in.
have little to no pores.
The measure of how easily water can flow through an aquifer.
porosity
permeability
gradient
divide
As permeability increases
Infiltration decreases and runoff decreases
Infiltration increases and runoff decreases
Infiltration decreases and runoff increases
Infiltration increases and runoff increases
What type of sediment tends to be the most impermeable?
sand
clay
silt
rocks
If water can easily move between cracks of a rock, we can say that...
water is permeable
rock is permeable
rock is impermeable
water is impermeable
What is porosity
Rocks
The percent of the volume of open spaces in rock or sediment
Ability rock sediment fluids pass through open spaces/pores
Nothing
If particle size decreases permeability
decreases
increases
stays the same
It could increase or decrease
Why does water move slowly through clay or not at all?
clay has large pore spaces
clay has hard particles
clay has very small particles
