but are categorized separately in others. Regardless, these eruptions are highly explosive — more than any other eruption type — rendering them extremely dangerous and destructive. Plinian eruptions take their name from the Roman naturalist Pliny the Elder, who died in the historic cataclysmic erupti...
What are the magma types in order of decreasing viscosity? What type of lava does a fissure volcano have? What type of volcano forms from tephra eruptions? What type of volcano is Llullaillaco? What type of volcano is Askja? What type of volcano is a stratovolcano?
Filament eruptions are interpreted either by a torus instability for an event occurring during the minimum of solar activity either by the diffusion of the magnetic flux reducing the tension of the restraining arcade. We concluded that CME models (tether cutting, break out, loss of equilibrium ...
The eruption of the Yellowstone supervolcano would be disastrous, so it's good to know that it probably won't blow again any time soon. Danny Lehman / Getty Images The Yellowstone National Park region has experienced three massive eruptions in Earth's history. The biggest of these major c...
A sunspot is an area of high magnetism on the sun’s surface which can release large eruptions of solar material into space called coronal mass ejections, as can be seen in figure 2. Sunspots can easily be seen by scientists from Earth and are identifiable as dark spots on the sun’s ...
Cinder cone volcanoes are one of two types of volcanoes that have a conical shape with steep sides. However, cinder cone volcanoes are much smaller than composite cone volcanoes. Answer and Explanation:1 Cinder cone volcanoes are made of collected debris from their eruptions. The lava in the vo...
It's important to note that there are three types of mercury: elemental, inorganic mercury and organic mercury (methylmercury). The latter two are not formed from cinnabar. Though all three can cause mercury poisoning, organic mercury is the most toxic. It takes 1,000 times the amount of me...
The three types of volcanoes are: Composite cone volcanoes: These types of volcanoes are conical in shape and contain layers of debris from lava, ash... Learn more about this topic: Types of Volcanoes | Definition, Characteristics & Examples ...
Volcanoes are one of nature's most destructive forces. However, volcanoes are also one of nature's chief constructive forces. Volcanic eruptions are responsible for creating new crust and geological landforms. The specific results of a volcanic eruption
In two subsequent steps, smaller-size granules of silicon carbide are used to smooth the surfaces of the rocks in preparation for polishing. Then, in the final step, a rock polish such as micron-size aluminum oxide is used to produce a bright, lustrous, polished surface on the rocks. The...
