of an Explosive Stratovolcano Eruption The pyroclastic material flung into the air, known as tephra, ranges in size from tiny dustlike particles – ash – to house-sized volcanic bombs. Eruption clouds may rise 25 or more miles into the atmosphere, and they can drop ash (as ashfall) hundre...
Why do volcanoes erupt in different ways? How can a volcano affect the world's weather? How do forests affect the water cycle? How are volcanoes harmful? How is water pollution affecting the hydrologic cycle? How does the rock cycle affect the Earth?
How do volcanoes form at convergent boundaries? How does a fissure volcano erupt? How are volcanoes created by tectonic plate movement? How are plate tectonics and volcanoes related? What causes intraplate volcanoes? How do glaciers cause erosion?
The structure of the volcano, and the intensity of the volcanic eruption, is dependent on a number of factors, primarily the composition of the magma. In the next section, we'll look at some different magma types and see how they erupt. Magma Eruptions Gas vents from Kilauea Volcano in ...
Some simulations report that the volcano will not become active, while others trend toward mechanical failure within the magma chamber, which can lead to an eruption. The process is very similar to how hurricane predictions are made. “When we do it with hurricanes, we'll see landfall maps...

However, volcanoes sometimes erupt in the middle of tectonic plates. The sources of these hotspots might be mantle plumes, mushroom-shaped pillars of hot rock ascending from the deep mantle to sear overlying material like a blowtorch. As tectonic plates wander over such plumes, geologists think ...

Chances are if you have made a model volcano, this was how you did it. Thebaking soda and vinegar reactionis nice because it's non-toxic and you can recharge your volcano to make it erupt again and again and again. Yeast & Peroxide Volcano ...
