Alright class, settle down, let’s take a peek,
At this word ‘aa,’ what does it mean, speak!
The dictionary tells us, clear as can be,
It's lava flow, for all to see.
Specifically from volcanoes bright,
Hawaiian-type, a wondrous sight!
It’s basaltic rock, dark and bold,
A story of the earth, ages old.
With jagged edges, rough and free,
And loose, clinkery – you'll agree!

So remember 'aa,' can’t be beat!
