A volcano is a vent in the earth that often forms a mountain built by lava and volcanic ash erupting and building up. A volcano not only releases ash and lava, it also releases gases. The gases are usually poisonus and contain sulfur.
Volcanoes
What is a volcano?
A volcano has many parts. One part of a volcano is the vent. The vent is where the lava, steam, ash, cinders, and smoke can travel. Another part of a volcano is the crater, the steep part of the top of a volcano. A parasitic cone is a smaller volcano that comes off of a volcano. Magma is stored under the volcano within the earth in a chamber called a magma reservoir.
What are the types of volcanoes?
There are three main different types
of volcanoes. One type is a Cinder cone volcano. A cinder cone
volcano explodes with in itself, dust flys into the air and the falls down
to the groud. This type of volcano usually is pretty steep.
A shield volcano is not very steep and lava just flows from the vent.
Another type is a composite volcano. A composite volcano is a volcano
that is not steep and is a combination of Cinder cone volcano and a shield
volcanco.
