  1. 1. Volcanoes
  2. 2. Types of volcano • Active • Dormant • Extinct • Are not expected to erupt again in the future. • Have not erupted for years but could still erupt. • Has erupted recently and expected to erupt soon. Over 1000 of these! Mix and match – which definition matches the key term?
  3. 3. 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.
