Distinguish between the different ways volcanoes cause damage.

The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.
