What is a Volcano? A volcano is a
mountain that forms when magma reaches the surface of the Earth.
Magma rises because it is less dense than the solid rock around it.

What are the parts of a Volcano?
1. VENT- the vent is the opening from which lava flows. Dust, ash, and rock particles can also be thrown out of the vent!

2. Crater- the top of the volcano. It is a funnel shaped pit. It is formed when the material explodes out of the vent!

3. Volcanic cone- is the pile of lava, dust, ashes, and rock around the vent. It can be found in different shapes!

Types of Volcanoes
• There are 3 types of Volcanoes:
ShieldCinder Cone Composite• They are classified by how they form.

Shield Volcano• Is wide and
somewhat flat.
• It forms from a quiet eruption.
• Lava flows out quietly and for great distances.

Cinder Cone Volcano
Has tall, very steep sides.
Has explosive eruptions.
This eruption produces a lot of cinder and ash.

Composite Volcano
Form from explosive eruptions.
Produce a lot of lava and ash.
Is small, with steep sides.

Smoke and steam hangs over the volcano under the Eyjafjallajo kull glacier in Iceland, which has erupted for the second time in less than a month, melting ice, shooting smoke and steam into the air and forcing hundreds of people to flee rising floodwaters. Volcanic ash drifting across the Atlantic forced.
