An explosion takes place‚ releasing the magma from a confined space‚ which is why there are often also huge quantities of gas and dust released during a volcanic eruption. The magma travels up the inside of the volcano‚ and pours out over the surrounding area as lava. One of the most

WHAT IS A NATURAL DISASTER A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods‚ volcanic eruptions‚ earthquakes‚ tsunamis‚ and other geologic processes. A natural disaster can cause loss of life or property damage‚[1] and typically leaves some economic damage in its wake‚ the severity of which depends on the affected population’s resilience‚ or ability to recover.[2] In 2012‚ there were 905 natural disasters worldwide‚ 93% of which were

of crust type either sial or sima. At a sima and sima divergence such as the Eurasian Plate and the North American Plate‚ both crusts diverge leaving magma to rise up. This with aid from the cool ocean water solidifies and creates gentle sloping volcanos with basic basaltic lava with low viscosity. The type of volcanoes found at these margins are shield and fissure volcanoes. At this specific plate margin‚ at the point of diverging‚ a mid-Atlantic ridge occurs. This is where magma has risen through

CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these
