Which component of soil can hold the least amount of water?
Gravel
What are the layers of soil called?
Horizons
How do the different structures of sand and clay affect the property of permeability?
Clay has smaller pores so water doesn’t flow through them as easily. Therefore, clay has less permeability.
Which has the least amount of permeability?
Soil 1
What is a common use for iron?
Which component of soil can hold the most water?
Clay
What is the definition that best matches the A Horizon?
Composed of mostly loose and partly decayed organic material
Which component of soil would go in spot 1 (Most amount of water)
Gravel
Which funnel probably contains the most gravel?
Soil 4
What are two uses of diamonds?
Jewelry and Drill Bit Tips

Electrical Wiring
A geologist is measuring the permeability of a layer of sediment. What question could she be trying to answer?
