Page 2 - Microsoft PowerPoint - 12.2 VOLCANIC ERUPTION

What are Volcanoes?

 A volcano is a landform, a mountain, where molten

rocks erupt through the surface of the planet.

 Volcanoes are ruptures in the crust of our planet Earth

that allow hot gases, molten lava and some rock

fragments to erupt by opening and exposing the magma

inside

 The volcano mountain opens downwards to a pool of

molten rocks underneath the surface of the earth.
