Alright class, settle down, let’s take a look today, At a word that carries worry, come what may! We're talking about “tsunami,” it’s true, A powerful force, for me and you. The dictionary tells us, clear and bright, It’s a huge wave, with all its might! (Rhyme Time!) "A very large and destructive wave," that's the key, Caused by a disturbance deep beneath the sea! Think of earthquakes rumbling low, Or volcanoes bursting, putting on a show. These big events create a mighty shake, And send these waves out for goodness sake! Now listen closely, this is important too, A tsunami isn’t just one wave, it's true! (More Rhymes!) “Usually a series of waves,” a wave train you see, Rolling and crashing powerfully, for all to agree! They can travel far, across the land, So always remember, understand? Do you have any questions about this powerful sight? Let’s discuss!
