2
Magma Chamber

• Lies inside the earth. Stores hot, melted rock
  called magma.

3
Central Vent

• Opening at the top of the volcano in which lava,
  pieces of rock and other materials pour out of.

4
Conduit

• Vertical channel or pipe in which magma moves up
  before it reaches the surface of the earth.

5
Crater

• Bowl-shaped hole which forms at the top of the
  volcano.

6
Lava Flow

• Lava is very hot when it erupts out of a volcano.
  The lava flows down the sides of the volcano.
  As it moves, the lava cools and hardens.

• Volcanoes are classified by
• Their shape
• The way they erupt
• The materials from which they are formed

12

• There are three main types of volcanoes that we
  need to learn about. They are
• Cinder Cone Volcanoes
• Shield Volcanoes
• Composite Volcanoes

13
Cinder Cone Volcanoes

• Cone shaped with very steep sides
• Relatively small-usually less than 300m (984ft)
• Built from lava fragments called cinders
• Very little lava
• Ex Paricutin in Mexico and Stromboli in Italy

14
Shield Volcanoes

• Looks like a shield
• Large mountains with gentle slopes
• Formed from lava that flows slowly from a crack
  in the Earths curst
• Ex Mauna Loa located in Hawaii is the largest
  volcano on Earth

15
Composite Volcanoes

• Looks like and upside-down V and has steep sides
• Formed from the most explosive volcanoes
• Eruptions usually occur without warning and can
  be very destructive
• Layers of rock and lava
• Ex Mount Fuji which is located in Japan
