Hello, everybody! How are you?
Hey, do you like to travel?
I love to visit and learn
about all the different places around the world.
I'd love to visit Japan or Hawaii, how about you?
Hey! Are you talking about travelling?
Yes, I am.
I love travelling, it's my favourite thing ever.
I swim in all the different seas and oceans
around the world.
And Katharine, do you know what my favourite destinations are
right now?
No, mermaid, tell me.
I love visiting volcanoes.
I get to visit fascinating islands at different countries.
Would you like to tell us about that, mermaid?
I'm sure we can learn a lot from you.
Yes, of course!
Let's go to Hawaii!
We can visit the Mauna Loa volcano, on the island of Hawaii,
it's the biggest one in the world!
It occupies half the island.
There is lava coming out of the crater on the volcano.
The crater is the hole at the top of the volcano.
Yes, and lava is magma which comes
from the interior of the Earth.
And out through the crater when the volcano is active.
No, let's go to Argentina.
We can visit the highest volcano in the world,
it's called Nevado Ojos del Salado.
And it's in the Andes, between Argentina and Chile.
Look, in Winter, it has snow on the top.
Wow, it's so beautiful.
When the lava comes out, it's called an eruption.
But this volcano hasn't erupted for a long time.
The last eruption was 1,300 years ago.
Do you know any other volcanoes with snow on top?
I think the Mount Fuji volcano, in Japan, has snow.
Am I right?
Yes, Katharine, you are!
Wonderful, here's a medal for you.
Thank you, mermaid.
So, our next stop is Japan.
Mount Fuji is an inactive volcano.
It last erupted in 1707, a long long time ago.
But the ashes reached Tokyo.
In 2021, a volcano on a Spanish island
started sending out ashes and lava into the air.
Do you know the name of the island?
Was it Ibiza, La Palma
or Mallorca?
I know this! It was La Palma in the Canary Islands.
Exactly, mermaid, well done.
And in the Canary Islands,
we can also visit the highest volcano in Spain.
The Teide volcano.
Scientists study this volcano
because its landscape and geology are similar to the planet Mars.
Our last stop is in Italy.
We can visit Mount Etna in Sicily.
It's an active volcano with magma inside.
In 2020, it erupted and lava came out.
Can you explain what magma is, Katharine?
Of course, mermaid, magma is a very hot liquid rock
beneath the Earth surface.
Has a very high temperature.
It's really hot!
And look, here, on this volcano, we can see all the different parts.
Here is the magma below the Earth surface.
And when there's an eruption, it comes out through the crater
and lava and ashes come out.
I hope you enjoyed visiting
all the volcanoes around the world with us.
See you next time, everybody! Goodbye!
