What is a volcano?
A volcano is a mountain that opens below
to a pool of molten rock called a magma
chamber below the surface of the earth.
When the pressure builds up, eruptions
take place. As well as lava and rock, a
volcano can trigger all these things:
tsunamis, flash floods, earthquakes,
mudflows and land slides.
7 Facts about volcanoes.
1. There are 1510 active volcanoes in the world many of them are
in the ring of fire.
2. The word volcano actually comes from comes the name of the
Roman god of fire, Vulcan.
3. The biggest known volcano in our solar system is on Mars. It’s
called Olympus Mons and it measures a gigantic 373 miles wide
and 13 miles high!
4. There are even volcanoes found on the ocean floor and even
under icecaps, such as some of the volcanoes in Iceland.
5. There are 3 stages of a volcano, (active, dormant and extinct.)
6. Some volcanoes are so big they are called a super volcano.

Where to find volcanoes
THE RING OF FIRE
The tectonic plates are
moving pushing up
and the magma below rises
forming a volcano and when
the pressure builds up
eruptions take place. The
ring of fire is on the edge of
several plates pushing
against others so there are
lots of volcanoes there.

Volcanoes around the world.
Mount Vesuvius, Italy
The biggest eruption of Vesuvius was
about 1900 years ago. The eruption that
destroyed Pompeii.
The bay by Napoli is still part of the super
volcano so Napoli beware!
It has one of the biggest magma chambers
in the world.
Popocatepetl, Mexico
Popocatepetl, which the is name the Aztec
word for smoking mountain, towers to 5426
metres. A plume of steam and ash rises
above it.
Tambora, Indonesia
The volcano that killed 92,000 people in 1
eruption.
It erupted in 1815.
And it was the biggest eruption in human
history, but not for long!
It is a huge volcano, but it used to be
bigger the eruption was so violent it blew
some of it apart.
Yellowstone, America
If this volcano erupts it will be the biggest
natural disaster ever. Its 40,00 years over
due so it could erupt soon. And then the
most of USA will be covered with ash.
Here is a picture of what Yellowstone
national park will look like if Yellowstone
erupts
Lake Taupo, New Zealand
It’s not a volcano anymore. When it
erupted in 1800 years ago it blew itself
apart, and became a lake. And when it
erupted even Spain was covered in ash,
luckily no-one lived in New Zealand then!
Eyjafjallajökull, Iceland
Nicknamed the big E and you can see why!
When it erupted in 2010 it cancelled jet flights in
Europe because the volcanic ash would put a
gloop into the engines and the jets would crash
and go boom
How I did it
I did it practically all by my self and my
mum and dad helped me a bit.
I went to the natural history museum and
that helped me.
My dad told me about some volcanoes and
I researched the volcanoes and got the
information.
That’s all folks!
