How does the amount of sorting impact porosity?

Sorted materials have a higher porosity

If a student poured water into each of the following, which would she find to be true?

Three of the columns would hold the same amount of water.

What is permeability?

The ability of water to pass through a material.

Which is true of vegetation?

Vegetation slows water down and increases infiltration

What is the definition of porosity?

The amount of pore space in a material.

What impact does the slope of the land have on groundwater?

The steeper the slope, the greater the runoff.

How does the packing of a material impact porosity?

Loosely packed soils have a higher porosity.

As permeability increases,

infiltration increases and runoff decreases

How does particle shape affect porosity?

Rounder particles have a higher porosity.

How does human activity impact infiltration?

It creates impermeable surfaces and more runoff
