How do volcanoes form?

• Magma rises through cracks or weaknesses in the Earth's crust.

• Pressure builds up inside the Earth.

• When this pressure is released, e.g. as a result of plate movement, magma explodes to the surface causing a volcanic eruption.

• The lava from the eruption cools to form new crust.

• Over time, after several eruptions, the rock builds up and a volcano forms.
