The cycle of lava as a destructive and constructive force, building the structure of volcanoes and powering their devastating impact.

Earth Science - Geology - Learning Points.

Volcanoes are landforms that occur along plate boundaries.

Volcanoes consist of a magma chamber, main and secondary vents and a crater.

Volcanic eruptions occur when pressure forces magma from the chamber to the main vent.

The pressure forces the crater to blow and release molten rock, ash and a cocktail of gases into the atmosphere.
