3 It is... an opening, or rupture, in the Earth's surface or crust, which allows hot melted rock, volcanic ash and gases to escape from below the surface.

4 Why does it look like a mountain? 1. Magma chamber 2. Bedrock 3. Conduit (pipe) 4. Base 5. Sill 6. Branch pipe 7. Layers of ash emitted by the volcano 8. Flank 9. Layers of lava emitted by the volcano 10. Throat 11. Parasitic cone 12. Lava flow 13. Vent 14. Crater 15. Ash cloud

5 Because melted rock of the past explosions became solid and gave the volcano the shape of a mountain.
