• Lava

• Magma chamber

• Mantle

• Magma

This is where the molten rock is stored beneath the ground.

• Magma chamber

• Main vent

• Secondary vent

Some magma may escape through the side of the volcano, particularly if the main vent becomes blocked.

• Main vent

• Secondary Vent

• Crater

• Magma chamber

This is the channel through which magma travels to reach the Earth's surface.

• Main vent

• Secondary vent

• Crater

• Magma chamber

This found at the top of the volcano, where the magma erupts from

• Secondary vent

• Main vent

• Crater

• Magma chamber

Tall, symmetrical shaped and can rise up 8,000 -10,000 feet. It’s explosion emits gases, ash pumice, silica lava ( called rhyolite ) and deadly mudflows ( lahar ).

• Shield volcano

• Cinder cone volcano

• Composite or Strato Volcano

Big that emits basaltic ( very fluid ) lava has long lasting mudflows , erupts gently and minimal. They have low slopes and large crater at their summits with flat round shapes around it.

• Shield volcano

• Cinder cone volcano

• Composite or Strato volcano

The magma inside a _____ has large amounts of gas trapped in it. Eruptions from _____ are violent and explosive because of all the gas trapped in the magma. They are usually only active for a short time and then becomes dormant ( inactive ).

• Shield volcano
