What is nitrogen?

This substance is a componentof soil with extremely small

particle sizes leading to a tendency to hold water.

What is clay?

The down slope movementof material under theinfluence of gravity.

What is mass wasting?

A metric prefix that meansone billion.

What is a Giga?

Made from an insoluble mineraland essential for plant life

it is the “P” in N-P-K.

What are peat, bituminous and anthracite?

This yellow element maybe added to the soil to

lower its pH.

What is sulfur?

This soil texture is idealfor growing plants and

consists of nearly equal amountsof sand, silt and clay.

What is loam?

These stair-step like structureshelp prevent soil erosion.

What are terraces?

These long chains ofsugar molecules provide

energy to animals when they are ingested.

What are carbohydrates?

Urea, nitrates and ammonia

What are usable forms of nitrogen?

These soils are high in iron andshow evidence of much oxidation due to their

orange or yellow colors.

What are “rusty” soils?

A period in U.S. history acharacterized by severe drought,

dust storms and erosion of farm land.

What is the Dust Bowl?

This form of carbon ends up in sea shells and coral reefs.

What are carbonates?

These sixteen elementsare essential

for plant growth.

What are macro and micro nutrients?

The holes in soil that collapsewhen the soil is disturbed.
