2. What is a volcano?
A volcano is an opening in the top of the Earth’s surface.
A volcano shoots out hot lava, which is melted rock.
A volcano’s lava is so hot that it burns everything in its path!
3. How does a volcano erupt?
• Inside a volcano there is a extremely hot liquid called magma.
• The magma rises to the magma chamber.
• The pressure pushes the magma up to the top of the volcano.

• Pressure on the magma gets stronger and stronger.
• Then , the Volcano erupts!
• When magma shoots out of the volcano it is called
lava .
