What plate boundaries to Volcanoes occur at? - Destructive and Constructive , How are volcanoes made up Constructive plate boundaries? - When the plates move apart, it creates a new pathway for rising magma to flow to the surface, What are Andean volcanoes produced by - oceanic and continental plates ( destructive ), Oceanic and Oceanic plates ( one plate is subducted ) creates an ______________ - Island- arc Volcano, What are the other 3 types of volcanoes? - Sheild volcanoes, Composite Volcanoes and Cinder/ spatter cones., How are volcanoes made up from Destructive plate boundaries? - When the tectonic plates are moving towards each other. Volcanoes are formed when either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate , What is an example of a Shield Volcano? - The Sierra Volcano in the Galapagos Islands, What is a Shield Volcano? - They are a gentle hill-like shape because they are built of successive flows of low-viscosity basaltic lava. This means the lava can flow for long distances, resulting in the greater size of shield volcanoes., What is a Composite Volcano? - They consist of alternating layers of tephra ( blocks, bombs and ash ) They have slopes that get steeper at the top of the volcano, How fast to Composite Volcanoes form? - They form relatively quickly and don't last very long, What is an example of a composite Volcano? - Cotopaxi Volcano in Ecuador, What is a Cinder cone? - They have straight sides, made up from fragments that are expelled from the volcano as a gas rich magma erupted., What are Cinder Cones made up of and what does it mean? - cinder cones are made up of loose fragments , so they have little strength and can be eroded away easily and quickly, What is an example of a Cinder cone? - Mt Capulin in New Mexico,
