Chapter 8- Water and Climate

Water flows through permeable materials ____________________ than impermeable materials.

• slower
• faster

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

Which diagram represents the soil with the greatest permeability?

• Choice 1
• Choice 2
• Choice 3
• Choice 4

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 how easily water can flow through an aquifer. 

• porosity
• permeability
• gradient
• divide

Rain and snowmelt that infiltrates the ground is called

• backflow

• groundwater

• spongate

• infiltrate

Which surface soil conditions allow the most infiltration of rainwater?

• steep slope and permeable soil
• steep slope and impermeable soil 
• gentle slope and permeable soil
• gentle slope and impermeable soil

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

• larger
• smoother
• rounder
• more soluble
