Volcanoes, Hurricanes, Earthquakes, and What?

Those who have known me a long time may be reminded of my old early-days-of-infancy-and-toddlerhood children updates when I recall the following anecdote.

The other night, Melanie asked Shayna, age 7, how her day at school was. Shayna began relating what her second grade class had learned about that day.

They were studying rocks and volcanoes. Shayna said they were studying, and here I quote:

"Volcanoes,
Hurricanes,
Earthquakes,
and Salamis."


Salamis?

"Yes," said Shayna.

You sure it wasn't Tsunamis?


"Oh," said Shayna, "yeah. Tsunamis."
