The diagram illustrates the principle of the volcanic eruption. In general, this natural phenomenon consists of several stages starting with the collection of magma inside the volcano and culminating in the magma flowing. At first, rocks located in the Earth’s core are melted under extremely high temperatures, forming magma. Being produced in massive amounts, the thick substance is next stored inside a magma chamber, ready to have erupted. When the volcano becomes active, the lava starts flowing through small cracks and the central vent in order to reach the outside environment. With sheer force, the hot compound is then blasted through the volcano’s mouth, which starts a volcanic eruption. During such events, half-molten solids, which are called bomb and scoria, can be found. After exiting the volcano, the magma flows down the mountainsides, causing havoc on its way by eliminating all signs of life. While the lava moves along the volcano’s sides, some of it can re-enter the volcano through a parasitic vent. Simultaneous with the eruption, a large amount of smoke, which is named an eruption column, files up to the sky, creating an eruption cloud that drops its ash to the ground.
