Soil Enrichment: Volcanic eruptions result in ash being dispersed over wide areas around the eruption site. And depending on the chemistry of the magma from which it erupted, this ash will be contain varying amounts of soil nutrients. While the most abundant elements in magma are silica and oxygen, eruptions also result in the release of water, ...
How did volcanoes form?
In short, Earth's atmosphere began to form after its formation 4.6 billion eyars ago, when volcanic outgassing led to the creation of gases stored in the Earth's interior to collect around the surface of the planet. Initially, this atmosphere consisted of hydrogen sulfide, methane, and 10 to 200 times as much carbon dioxide as today's atmosphere.
What are the elements that are released during magma eruptions?
While the most abundant elements in magma are silica and oxygen, eruptions also result in the release of water, carbon dioxide (CO²), sulfur dioxide (SO²), hydrogen sulfide (H²S), and hydrogen chloride (HCl), amongst others. In addition, eruptions release bits of rock such as potolivine, pyroxene, amphibole, and feldspar, ...

More than 80 percent of the Earth's surface--above and below sea level--is of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth's earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life. Over geologic eons, countless volcanic eruptions have produced...

The importance of volcanoes
Volcanoes have had a tremendous impact on the Earth many times throughout its history – this applies to both the landscape and the world of living organisms.
Why is volcanic ash a threat?
To understand why volcanoes affect living organisms so strongly, it is necessary to learn more about what pyroclastic materials actually are. The easiest way to say is that these are lava fragments, as well as rocks torn out of the ground. Pyroclastic materials are divided into many types.
The benefits of volcanic ash
The same properties of volcanic ash (as well as other pyroclastic materials) make its presence beneficial. It contains huge amounts of elements such as potassium, calcium and magnesium, which are essential for the growth and development of organisms. It also contains admixtures of trace elements, e.g. selenium, cadmium or cobalt.
