Write a short article nigh a major volcanic eruption - Essay ExampleVolcanoes are powerful forces of nature. According to Ritter et al., volcanism is only when the manifestation of processes that occur in earths mantle on the surface of the earth (1). Rocks and minerals are liquefied into magma in earths mantle due to heat produced by extreme pressure. Weaknesses in the earths perkiness allow vents to form that allow magma to escape. This magma can emerge through the crust under the sea or on dry land. These vents will create three possible types of volcanic landforms. The type of landform is dictated by the mineral make-up of the magma that is expelled through the vent (2). Shield volcanoes, such as the Hawaiian Islands are made of magma that has low viscosity. It is mostly basalt and runs like water. Cone volcanoes are made of magma that is tall in silica. The magma is sticky so it builds up making the steep sides of a cone shaped mountain. quasi(prenominal) to these are comp osite cones that are made of magma and ash. They are irregularly shaped volcanic mountains. A lowest landform created by volcanoes is called a caldera. This is a huge empty space in the volcanic mountain created by a massive eruption. This is a prominent feature that was created by the eruption of Thera.The Greek island of Thera is located in the Mediterranean Sea just northeast of the island of Crete. The island is known in modern times as Santorini. The geologic shape and structure of the island is typical for volcanic islands in the Aegean and Mediterranean seas. The island was a mixture of ash and silica based materials with gentle slopes near the shoreline rising to an inland, conical peak. Thera had been slowly building for at to the lowest degree a million years. The current arrangement of the small islands of Santorini did not happen with just one eruption. As many as twelve eruptions over the past million years have made Santorini what it is forthwith (3). The eruption that occurred around 1600 BC was,
