How does a volcano form?VolcanoesVolcanoes are an amazing thing to behold: the explosion of thousands of tons of earth and ash into the sky, rolling black clouds blasting energy outward from the volcano's peak. Their fireworks show is impressive, and being able to observe these natural ...
Use salt dough, plaster or papier-mâché to form a mountain around an empty 2-liter bottle placed upright at the center of the plywood base. Be sure to leave the lid off. Step 3 Form the model volcano's open top tightly around the mouth of the bottle. Step 4 Make ridges and chann...
The cardboard volcano is a dramatic way of demonstrating chemical reactions. When vinegar and baking soda combine together, they rapidly release carbon dioxide gas, causing the liquid to bubble up violently. This reaction is dramatic enough on its own, but when it occurs inside a cardboard volca...
STEP 2: You want to form the salt dough around a small empty water bottle. Create a composite or shield volcano shape that you learned about above.Depending on the shape you want, the time to let it dry, and the bottle you have, you might want to make two batches of salt dough!
If the magma pressure rises to a high enough level, or a crack opens up in the crust, the molten rock will spew out at the earth's surface. If this happens, the flowing magma (now called lava) forms a volcano. The structure of the volcano, and the intensity of the volcanic eruption...
When magma finds a way to escape from beneath the earth's surface,it creates a volcano. Volcanoes erupt in different ways. Some, like Mount St. Helens,explode. Explosive eruptions are so powerful, they can shoot particles 20 milesup (32 kilometers), hurl 8-ton boulders more than a half...

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 ...
A volcano is a fissure – opening or vent – in the earth’s crust through which molten rocks and gases erupt. The molten rocks can be in the form of mixture of hot gases, ash, lava, or other extremely hot substances within the earth’s crust. ...
This is me, like the god of fire in a volcano, about to make the volcano erupt. Just as I was on my deathbed, my classmate Sun Junwen offered me a bottle of water to help me, the god of fire, extinguish the fire. LastAugust , most areas of Guangxi have experienced severe drought...
