- Volcanoes are found at destructive and constructive plate margins
- At destructive plate margins, the oceanic plate submerges beneath the continental plate as it is more dense
- The oceanic plate moves down into the mantle - where it is melted and destroyed
- A pool of magma forms
- The magma rises through cracks in the crust called vents
- The magma erupts onto the surface, cooling to form a volcano
- At constructive plate margins the magma rises up into the gap created by the plates moving apart, forming a volcano
- At destructive plate margins, the oceanic plate submerges beneath the continental plate as it is more dense
- Some volcanoes form over parts of the mantle that are really hot, they are called hotspots
- An example of this is in Hawai
- There are 3 different kinds of volcano:
- Composite Volcanoes - eg. Mount Fuji in Japan
- Made up of ash and lava that's erupted…
- Composite Volcanoes - eg. Mount Fuji in Japan
