Description

In more violent eruptions, the magma conduit is cored out by an explosive blast, and solid fragments are ejected in a great cloud of ash-laden gas that rises tens of thousands of metres into the air. In 1991, Mount Pinatubo in the Philippines ejected sulphur dioxide which formed a haze of sulphuric acid. The majority of the Earth's volcanoes are located along tectonic plates because, when tectonic plates collide, one tectonic plate will slide and move under another one, forming a volcano. If eruptions of cinder and lava flows happen repeatedly from the same vent, the overlapping layers can form a composite volcano (stratovolcano). Most earthquakes and volcanic eruptions do not strike randomly but occur in specific areas, such as along plate boundaries.

The somma-stratovolcano, Mount Vesuvius (last erupted in March 1944) lies in the Gulf of Naples in Campania, Italy. The water that gets trapped in the process will start to boil (due to the high temperatures) and begin to melt the rock. Evacuate immediately if close to the volcano to avoid flying debris, hot gases, ash, lateral blast, and lava flow. In other cases, entrapped gases tear the magma into shreds and hurl viscous clots of lava into the air.The Pack of Pompeii' from Twinkl Originals is the perfect book to use in your topic about volcanoes for this exact reason.

Strictly speaking, the term volcano means the vent from which magma and other substances erupt to the surface, but it can also refer to the landform created by the accumulation of solidified lava and volcanic debris near the vent. On land, volcanoes are often found along the edges of tectonic plates, and beneath the ocean, they form underwater mountain ranges.On our planet, volcanoes often sit in tectonic plates that are converging or diverging, and numerous of them are located underwater. In the United States, volcanoes in the Cascade Range and Alaska (Aleutian volcanic chain) are part of the Ring, while Hawaiian volcanoes form over a 'hot spot' near the center of the Ring. Sometimes beginning with an accumulation of gas-rich magma (molten underground rock) in reservoirs near Earth’s surface, they can be preceded by emissions of steam and gas from small vents in the ground.
