The exothermic (heat producing) reaction between potassium permanganate (KMnO 4), a strong oxidizing agent, and glycerol (C 3 H 5 (OH) 3), a readily oxidised organic substance, is an example of an experiment sometimes referred to as a "chemical volcano". [7] [8]
A supervolcano is a volcano that has had an eruption with a volcanic explosivity index (VEI) of 8, [1] the largest recorded value on the index. This means the volume of deposits for such an eruption is greater than 1,000 cubic kilometers (240 cubic miles). [2] Location of Yellowstone hotspot over time.
The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana. [4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
Seismic unrest can be a sign that a volcano is waking up, but the full story is much more complex. Both Campi Flegrei and the Long Valley Caldera are known as supervolcanoes, a term used to ...
The only semi-recent example was the 1815 eruption of Mount Tambora, which led to worldwide cooling and agricultural failures and caused 1816 to become known as the "year without a summer."
Scientists discover that the volcano under Yellowstone is much bigger than previously thought.
Products of volcano-ice interactions stand as various structures, whose shape is dependent on complex eruptive and environmental interactions. Glacial volcanism is a good indicator of past ice distribution, making it an important climatic marker.
Organic products can vary a lot in price. According to a study performed by consumerreports.org, organic products compared to non-organic products ranged anywhere from 13 percent cheaper to 303 percent more expensive. The reason why organic products cost so much more on average is the production process. Many factors contribute to this cost.
