Elementary (K-4), Lithosphere, Oceans
None alike and none the same.
Some are warm and some cold.
Can you find one on a globe?
Now take your finger and go around.
Follow the ocean between the ground.
Keep on going just for fun.
Are there many oceans or just one?
Stretching far from shore to shore.
Past the beach, across the ocean floor.
To tell you would take too much time.
But would you at least read this rhyme
About Earth's ocean land?
Not just on beaches or made of sand.
Mountains, valleys, plains and more.
What else is down there off the shore?
If you think that ocean land.
Is like the land on which you stand.
You'd be right in some ways yes.
But is it different more or less?
If you walk along a beach.
Places with ocean land you reach.
You might see sea shells in the sand.
Do dead things' shells become ocean land?
If you took a glass-bottomed boat.
Or did some snorkeling while you float.
You might see rocks, reefs and sand.
But that coral? Now, is that land?
If you wore some scuba gear.
Went down out past the beach that's near.
You might find the bottom drops.
How far down does it go before it stops?
What if you went down in a diving bell.
And your trip went very well.
Could you see a mountain range?
Volcanoes, too? Would that seem strange?
If you could stand on some ocean floor.
In a special suit or something more.
You might feel it move and shake.
Could this quake a tsunami make?
If you took a deep sea submarine.
Down to cold, dark places rarely seen.
You might see a canyon grand.
Did it form like those on dry land?
If you sent a robo sub with an arm.
Down to depths that could do you harm.
You might see some lava floes.
Could that be how ocean floor grows?
If you could drain the oceans dry.
And see ocean land against the sky.
You'd see things that might make you wish.
Why wasn't I born more like a fish?
Some say there is a change out there.
That could change Earth's ocean air.
How could that change Earth's ocean land?
And the land on which you stand?
