A volcano forms when the tectonic plates push together and upwards forming a tower. Volcanoes can also
be very dangerous.
What is the hole in the middle called?... It’s hot and comes out the crater...
A C T I V I T I E S
Lava can be as hot as 1 000ºC. Smoke
and ash also come out of a volcano.
The crater at the top of the chimney
is where the magma comes out.
Pressure and heat forces the magma up from
inside the Earth. This forms the
chimney
.
The magma chamber is the large
pool of magma under a volcano.
Sometimes the magma pushes
up through the chimney and
the volcano erupts. Magma
becomes lava in an eruption.
