    • 1. What Are Volcanoes? • A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. • In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt. • From: http://www.woodlands-junior.kent.sch.uk/Homework/mountains/
    • 2. What do Volcanoes look like? A volcano is a big mountain that has a big circle hole at the top of the mountain. After an eruption a volcano is very grey/black/brown with red/yellow/orange lava around the top.
    • 3. How do Volcanoes erupt? • Volcanoes are formed when there is a great pressure inside the earth’s crust and the force of the magma reaches so high that it finds its way upward causing an eruption. From: http://www.letusfindout.com/how-do-volcano- erupt/
