The kids are given a tour around the volcano by Lu. Volcanoes are present not only on land, but also in both deep and shallow ocean waters! Volcanoes found under the water are called submarine volcanoes and their eruptions can push ash and volcanic gases up through the water and onto the surface. Some submarine volcanic eruptions have been so massive they have been known to produce entire islands.

Here we are.
- A real life submarine volcano.
- Uh, this is pretty interesting, Lu, but, uh, where'’’s the fire?
- Well, it'’’s not exactly fire.
There'’’s a molten substance-- - Yes, called "magma."
- Magma, thank you, Bobby, that comes out of the top of the volcano.
And you want to stay away from that magma because, boy, it'’’s very, very hot.
Hot enough to even melt rocks!
- Oh.
- Wow!
- Not my rock collection!
- Your rock collection is safe, Dunk.
As long as they don'’’t get dropped into the volcano, that is.
Okay, who'’’s ready to climb a volcano?
all: We are!
- Oh, this is gonna be so much fun.
- Oh, I know.
- Cannot wait.
- Everything we'’’re swimming over right now, this whole mountain, was made from magma cooling in the water.
After each eruption, magma pours out, then cools, making the "mountain" a little taller each time.
Isn'’’t that something?
- Yeah--hey, let'’’s go right to the top.
- Oh, first, we just need to make sure this volcano isn'’’t gonna erupt before we get too close.
- Uh, yeah, that sounds like a good rule.
- Is there a way to tell if a volcano'’’s about to erupt?
- One sign an eruption'’’s coming is there'’’d be shaking.
- Hmm.
- Whoa!
- Hey, Bubbles.
Did you feel that vibration in the water?
- Yeah, did you feel it?
- Yeah, I sure did.
- Just out of curiosity, what are one of the other signs that an eruption is about to take place?
- Oh, well, there'’’d be big plumes of ash coming out of the volcano.
- [gasps] You mean like that?
- Oh, yeah, that'’’s the one.
- The final sign would be red hot magma oozing out of the top of the volcano.
If that happens, we want to be safe and get far away from it.
