Volcanoes 01/22/13

Definition A volcano is an opening in a planet's crust, which allows hot magma, volcanic ash and gases to escape from the magma chamber below the surface.crustmagmavolcanic ash

How do they form? Volcanoes form often at plate boundaries. Divergent Boundaries form a. - Mid-ocean Ridge; or -Rift Valley

Convergent Boundaries Oceanic – ContinentalOceanic - Oceanic TrenchMid-Ocean Ridge creating an island arc Andes MountainsJapan; Hawaii

How do they form? 3) Hot Spots: columns of hot magma rising from a thin spot in the Earth’s crust. As the plate moves, so does the column of lava, creating island chains. Real life Example: HAWAII

Types: (nope they aren’t all the same) Shield, Cinder Cone and Composite volcanoes.

So what does it look like?

Shield Volcanoes Shield volcanoes slowly erupt. They are large in size and don’t make huge peaks, they are more like a gently sloping mountain where one layer of lava cools hardens and another layer flows on top. Ex: Hawaiian islands.

Shield Volcanoes - pictures

Cinder cone Volcanoes Produces high viscosity lava with ash, cinders and bombs. Explosive eruptions. Form a cone like mountain.

Cinder cone volcanoes Video: es&view=detail&mid=B8B605F B8B605F &first=0&adlt=strict#view=detail&mid=1CE981DEA3 D53BF3F3061CE981DEA3D53BF3F306 es&view=detail&mid=B8B605F B8B605F &first=0&adlt=strict#view=detail&mid=1CE981DEA3 D53BF3F3061CE981DEA3D53BF3F306

Composite Volcanoes Lava flows alternate with explosive eruptions of ash, cinder and bombs. They are tall, cone shaped mountains where layers of lava alternate with layers of ash. EX: Mt. Fuji, Mt. Saint Helens Video: view=detail&mid=2CDF551F7B6426E174912CDF551F7B6426E 17491&first=0&adlt=strict#view=detail&mid=6B50410E72C30 DFB3A2D6B50410E72C30DFB3A2D view=detail&mid=2CDF551F7B6426E174912CDF551F7B6426E 17491&first=0&adlt=strict#view=detail&mid=6B50410E72C30 DFB3A2D6B50410E72C30DFB3A2D
