"Alexa,  Talk dirt to me."

"Dirt:  Synonym - Soil.
Soils are chemically different from the rocks and minerals from which they are formed in that soils contain less of the water soluble weathering products,
calcium,
magnesium,
sodium,
and potassium,
and more of the relatively insoluble elements such as iron and aluminum."

She continued with the heavy elements,
But I really didn't care,
By the time she'd got to potassium,
I was pretty much already there.
