Volcano Notes A volcano is a place (usually a mountain) where magma reaches the earth’s surface.

Lava- Vent- Magma Chamber Volcano Anatomy Crater- Erupted magma The opening in the volcano Pit at the top of the volcano Magma Chamber

Four things that can come out of a volcano

1. Lava: molten rock that flows or oozes onto the earth’s surface

2. Lahars: flows of mud, rock and water

3. Pyroclastic flows: hot avalanches of ash and gas

4. Tephra: gases and fragments of rock and lava sent high into the sky

Three Types of Volcanoes 1. A cinder cone volcano has steep sides and is made from explosive eruptions of small particles of rock that form a loose pile of volcanic rock fragments.

Three Types of Volcanoes An example of a cinder cone volcano is Paricutin in Mexico.

Three Types of Volcanoes 2. A shield volcano is built up of many slow thin layers of hardened lava.

Three Types of Volcanoes An example of a shield volcano is Mauna Loa Volcano in Hawaii. It is the worlds largest shield volcano.

Three Types of Volcanoes 3. A composite volcano is usually cone-shaped and is built up of layers of hardened lava and rock fragments.

Three Types of Volcanoes Mount St. Helens is a Typical composite volcano.

Three Classifications of Volcanoes: Active Volcano: A volcano which has erupted recently or might erupt soon.

Three Classifications of Volcanoes: 2. Dormant volcano: A volcano that has been quiet for a long time, but still has signs it may erupt again.

Three Classifications of Volcanoes: Extinct volcano: A volcano that has not erupted for thousands of years and cannot erupt again.
