What is a Volcano?
3
Volcanoes are mountains that are different
from other mountains because of the way they are
formed. They are formed by eruptions which cause
lava to come out and accumulate on the
surrounding land.

During the eruption of a volcano, flowing lava
and ash, harden around the opening out of which
they came, forming a large cone. This cone is
what we know as a volcano.


7
Volcanoes form in the ocean as well as on land
creating new islands. As the lava flows, the
islands are gradually formed.
8
The intense heat of the lava destroys everything
in its path.
9
As the lava flows it begins to cool on the
outside surface but yet holds its intense heat on
the inside, just like a bowl of soup.
10
Volcanoes change the face of the earth in many
different ways. They can affect plant life,
animal life, and land formation. In 1981 Mt. St.
Helens in Washington State erupted.

Several years after the eruption, evidence of the
destruction from the hot ash and debris is still
there.

After the eruption

Volcanoes are also good
Volcanoes form islands, destroy mountains,
produce new soil, and generally give the Earth a
facelift every few million years
After a volcano erupts, and becomes inactive
(isn't likely to erupt again), the soil around
the old volcano is just super for farming. I mean
just SUPER!!! You can grow anything in that old
volcanic ash!

Many volcanoes can be found throughout the world.

New Zealand
Japan
Hawaii
Antarctica
Russia

Match the number to the continent or
area. Antarctica Africa North
America South America Europe
Pacific Ocean Central America
Asia Atlantic Ocean

Volcanologists are scientists who study
volcanoes. It is very interesting but can be
dangerous work. They study both the inside and
outside of the volcano.
