How a Volcano EruptsA volcano is any opening in the Earth’s surface that allows molten rock and volcanic gases to escape from far below the Earth’s surface. Although many volcanoes are mountainous in shape, a volcano can exist in nearly any form, including volcanic vents on the ocean ...
This volcano glows blueunder a black light. That doesn't make it any morelike a volcano than the other projects, except that lava is hot and glows. Glowing eruptions are cool.

When a volcano erupts, lava may flow out. How does this lava flow affect the nearby forests? A. It will make the forests grow more luxuriantly because the lava contains a lot of water B. It will completely destroy the forests because of the high temperature and large area of the lava ...
When a volcano erupts, sulphur dioxide is released into the atmosphere, where it turns to sulfuric acid. Acid levels in the Greenland ice sheet are helping researchers study volcanic eruptions and their effects on climate. Example: Krakatau (near Java & Sumatra); Tambora (in the East Indies)...
How is magma stored under a volcano? How does subduction produce magma? How do volcanoes become dormant? How do volcanoes cause lahar flows? What happens to lava after it erupts from a volcano? Why do earthquakes occur before a volcano erupts?
a central vent - leads from the magma chamber to the summit crater. The biggest variation in volcano structure is the edifice, the structure surrounding the central vent. The edifice is built up by the volcanic material spewed out when the volcano erupts. Consequently, its composition, shape an...
Why do earthquakes occur before a volcano erupts? How long can volcanoes erupt for? How are volcanoes created at the Mid-Atlantic Ridge? How does plate tectonics affect the rock cycle? What causes hot spot volcanoes? How do hot spots create volcanic mountain ranges like Hawaii? How are volcan...

Generally, volcanologist prefer to talk about eruptive phases of a volcano that belong to one single eruption: two or several eruptive events separated by a pause in activity, which can span hours to even weeks. However, it is often impossible to give a final answer to whether two eruptive ...
