Great photo, Ms. Sue!! Perfect illustration.
Brennon, it's called a delta because it's in the shape of the capital delta in Greek, which just looks like a triangle: http://upload.wikimedia.org/wikipedia/commons/6/60/Greek_delta.png

A delta is a term used in mathematics, physics, and other disciplines to represent a change or difference between two values. It is commonly denoted by the Greek letter Δ (delta). The concept of delta is particularly useful when comparing initial and final states of a system or when quantifying the rate of change of a quantity.
