Is volcano a natural disaster?
Volcanic eruptions are natural disasters because they release massive amounts of matter and energy in a very short time. If this occurs near human population centers it is possible for there to be so much damage the event would be called a disaster. Because humans are unable to have any control over volcanos erupting and because these events would happen even if humans were not on earth they are natural disasters.
What do only the most violent volcanic eruptions feature?
The most violent volcanic eruptions are found in destructive/convergent plate boundaries. 80% of the world's active volcanoes are found occur along destructive boundaries. Acid-lava and composite volcanoes also cause the most violent eruptions as the lava is viscous and the opening of the volcano is sometimes blocked by hardened lava, causing a huge massive explosion during the eruption.
Do some types of volcanic activity not involve the eruption of magma?
True. Many eruptions produce massive clouds of ash, gas, and pumice rather than lava. Phreatic eruptions, as another example, are essentially steam explosions.
Is a tsunami a type of weather?
No, tsunamis are caused by earthquakes, volcanic eruptions, or asteroid impacts, which then displace a massive amount of water, in the form of multiple tsunami waves. Earthquakes, volcanoes, and asteroids have nothing to do with the weather.
How are the Tambora and Krakatau eruptions similar?
The 1815 eruption of Mount Tambora and the 1883 eruption of Krakatoa were the largest volcanic eruptions in human history. Both were extremely violent Ultra Plinian eruptions, which spew massive amounts of ash miles into the atmosphere. They were also caldera-forming eruptions, meaning that they drained so much magma from underground that they collapsed into the space left behind. The eruption of Krakatoa produced about 20 cubic kilometers of ash while the eruption of Mount Tambora produced about 160 cubic kilometers.
What element could start an ice age?
Massive Volcanic Eruptions hence ...Ice Age
What is a volcano explosive index?
Volcanic explosive index is a measure of how explosive a volcanic eruption is based largely on the amount of material released. It ranges from VEI-0 for non explosive eruptions to VEI-8 for massive super eruptions.
What causes masive climate changes?
global warming, massive (vei8) volcanic eruptions & meterorite hits (ask the dinosaurs)
What are massive slabs of rock which move on the earth's surface colliding with one another and generating earthquakes and volcanic eruptions?
Tectonic Plates

What event appear to separated succeeding geological period?
There are often very large meteor impact events and/or extended series of massive volcanic eruptions.

How could volcanic ashh reveal dinosaures bones?
Volcanic eruptions can bury a whole ecosystem in ash, which preserves a massive number of organisms perfectly, like a prehistoric version of Pompeii. In Asia, some such eruptions buried a wide array of plants and animals, providing a detailed look at the ecosystem of the area. Details all the way down to the feathers of creatures such as Microraptor were preserved by the ash.
How did plate tectonics cause the formation of the hawaiian island?
The shifting of plates in the earth cause massive underwaer volcanic eruptions. Over time, the eruptions of the volcanoes cause a buildup of dried lava that eventually breached the surface of the ocean. These volcanoes are still erupting, causing the island to gradually grow.
What happen to create a caldera?
Calderas form during massive explosve volcanic eruptions. In such eruptions so much material is expelled that it leaves a large empty space under the volcano. The volcano then collapses into this space, forming a giant crater.
Is a tsunami a type of weather?
