Revise: Tectonic Plate Movement: VolcanoesA volcano forms where molten rock reaches the Earth’s surface through an opening called a vent. Below the surface, molten rock is called magma; once it erupts, it is called lava. Magma may collect beneath a volcano in a magma chamber before rising through the crust.
For an explanation, link plate movement to magma reaching the surface, then link lava properties to the volcano’s shape and eruption style.
Use ‘usually’ or ‘typically’: shield volcanoes are commonly associated with constructive boundaries and hotspots, while composite volcanoes commonly occur at destructive boundaries.
