Evidence which supports the statement

Volcanic events are typically events which occur as a direct result of a volcano, where debris and molten rock are both extruded and intruded during an eruption. The plate tectonic theory was developed by Alfred Wegener in 1912, however initially his theory of how the plates all ‘fit together’ was ignored as there was simply not enough evidence. After technology had significantly advanced later in the 20th Century, the theory was developed further by several scientists. This theory suggests that the crust is split into a number of plates, all of which float on molten mantle rock and are constantly moving on the Earth’s surface. We are also now aware that there are two types of plate, oceanic and continental and it is the movement of these two plates that can cause both volcanic and seismic events. However these events are not the only pieces of evidence that prove the plate tectonic theory is valid; there are many other factors which include sea-floor spreading and fossil distribution.

Pyroclastic materials and molten magma escape the mantle and emerge above the Earth’s crust through volcanos. All of Earth’s active volcanos are distributed in clusters around the pacific ocean, southern Europe, the east coast of Africa and through the Atlantic Ocean. These specific locations are all as a result of the nearby constructive and destructive tectonic plate boundaries, this is known as ‘The Ring of Fire’. It is named so because of the large concentration of a large, ring like formation of volcanos around the Pacific Ocean, which provides strong evidence for the above theory and statement. The reason there is specific interest in ‘The Ring of Fire’ is that it is a plate (the Pacific Plate), which borders 5 other plates (Indo-Australian, Philippian, Eurasian, North-American and South-American). This pattern shows a very strong
