Key Stage 2
Meaning
A volcano is a mountain made from lava that has cooled to become rock.
Key Stage 3
Meaning
A volcano is a mountain made from lava that has cooled to become igneous rock.
About Volcanoes
- Volcanoes are usually found near the boundaries between tectonic plates.
Key Stage 4
Meaning
A volcano is a mountain made from lava that has cooled to become igneous rock.
About Volcanoes
Volcanoes are usually found near the boundaries between tectonic plates.
How Volcanoes are formed
Volcanoes are formed along 2 different types of tectonic plate margin; Destructive Plate Margins and Constructive Plate Margins.
At Destructive Plate Margins more dense oceanic plate moves under the less dense continental plate. As this happens the oceanic plate is melted and a lot of magma forms. This magma then rises towards the surface of the crust through cracks in the crust called vents. As this magma reaches the surface it creates a Volcanic Eruption due to high pressure being relased and a volcano is formed.
