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 ...
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 ...
So if Mount Agung erupts violently, but doesn't sends massive amounts of sulfur dioxide into the air -- or doesn't send it high enough -- a longer-term global effect is unlikely. If this eruption is like previous eruptions of this volcano, though, then it will likely blast a significan...
When a volcano erupts, magmacomes out. The colour of magma is red, but when magma is cooled andbecomes solid rocks, it becomes black.Sothetemperatureis high enough to metrocks.所以温度高到足以融化岩石。be . enough to .足够……去……e.g. She is clever enough to solve this problem.她...
In some instances, the magm a ascends into the crust and remains there in large pools, but on other occasions, the magm a reaches the surface and erupts. The place where the lava, as magm a is known when it is on the surface, emerges from,often in a violent manner, is a volcano...
domes or mountains. Magma is molten rock within the earth's crust that becomes lava when it erupts. Rock also comes from volcanoes in the form of ash, finely powdered rock that looks like dark smoke. Just a few steps can help you to create your own model volcano that erupts and blows ...
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...
M:Yes.I will even order a pizza with mushrooms!W:OK,Michael.I will try this last ride.M:Great,Mary!I know you will enjoy this.Did you know when the volcano erupts,our seats shake?I heard it is quite an experience.Look at the people getting off the ride.They look very satisfied.W...
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, 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)...
