Saint Helen's Volcano acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677504 Mt. Saint Helen's volcano is a steep-sided volcano composed of many layers of volcanic rocks, usually made from high-viscosity lava, ash and rock debris. ]]> 2016-11-18 13:12:05 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677504 What type of volcano is it? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677904 Composite volcanoes]]> 2016-11-18 13:14:00 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677904 How does this type of volcano form? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677995 plates push up and then spread apart causing the magma to come up and erupt. ]]> 2016-11-18 13:14:25 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138677995 Is it associated with a specific plate boundary? If so, what type of plate boundary is it associated with? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678117 Yes, the plate boundary is a subduction plate .]]> 2016-11-18 13:14:58 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678117 What is happening in the Earth’s crust (at that plate boundary) that forms this volcano? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678218 The plates shift and seperate which lets lava flow up and harden. Eventually build a mountain form.]]> 2016-11-18 13:15:26 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678218 What type of magma (mafic, felsic, etc…) does it produce? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678730 explosive pyroclastic eruptions]]> 2016-11-18 13:17:25 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138678730 How fast can the magma flow? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138679857 It depends, but has been recorded from 6 to 40 miles an hour.]]> 2016-11-18 13:21:43 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138679857 What causes it to be either explosive or non-explosive? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138684542 Two important traits that characterize volcano's explosiveness and viscosity. A eruption begins when magma, the molten rock from deep in the Earth's crust, rises toward the surface. Dissolved gases in the magma determine weather it will be explosive or not.]]> 2016-11-18 13:38:14 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138684542 What are the precautions and emergency procedures that take place before and during a volcanic eruption? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138737169 Stay out of the area defined as a restricted zone.  Avoid river valleys and low lying areas.
Safety Tips Before:
• Stay away from active volcanoes.  
• If you live near an active volcano, keep goggles and a mask in an emergency kit, along with a flashlight and a working, battery-operated radio.
• Know your evacuation route. Keep gas in your car.

If so, how? What pieces of information do they use to help them make these predictions? acsnelli93 https://padlet.com/acsnelli93/hho31vuibtzc/wish/138743923 Yes, somewhat but it is very hard to do.  They predict a volcano’s vital signs. Seismometers can be used to pinpoint earthquakes which track the rise of magma and its movement. They Instruments that sniff SO2, CO2 and other gases also can signal changes in the volcano. ]]> 2016-11-18 16:06:19 UTC https://padlet.com/acsnelli93/hho31vuibtzc/wish/138743923 When did it erupt last?
