Volcanic eruptions are caused by the magma in the upper part of the upper mantle inside the earth. Due to the movement of the earth’s plates, a fault zone is formed, that is, a volcanic channel. Under extreme pressure, magma will break through the crust from the weakest point along the volcanic channel and erupt out; thus, forming a volcanic eruption.
When it comes to volcanoes, our minds will naturally associate with the picture of volcanic eruption, so how is volcanic eruption formed? The following small series will explain to you.
Details
01
Volcanic eruption is a professional terminology of geology. It is a strange geological phenomenon, a manifestation of crustal movement, the strongest display of the earth’s internal heat on the surfac
02
In ancient Rome, people saw the phenomenon of volcanic eruption, the mountain in the cause of combustion for fire creature card (Volcano) to anger, and southern Italy in the Mediterranean and parry islands Wu Er named kano Volcano is created, but also become the English name of the word Volcano Volcano.
03
Magma is divided into primary magma and regenerated magma;Native magma is formed by molten material captured by the core, and the core captures molten material and some other substances to form a huge thick molten layer, which is unevenly composed of these substances, and the original magma solidifies to form the most primitive earth’s crust.
04
The various types of intrusive rocks we see, such as ultramafic rocks, mafic rocks, neutral rocks, acid rocks and alkaline rocks, as well as various magma ejected by volcanic eruptions, are all regenerated magma, but the source depth, channel material composition and degree of differentiation are different.
05
Recycled magma includes magma derived from native magma and heavy lava magma; The liquid layer of the Earth consists of regenerated magma formed by native magma mutations – formed by changes in temperature, composition and physical state.
