Deffence between earthquake and volcano
Answers
are as follows
(1) volcano eruption Lava comes out but in earthquake no Lava comes out
(2) volcano eruption is there are too many volcanoes. Bbut earthquake or along the ages of tectonic plates
(3) volcano eruption causes by the interaction of the plates and not the movement of Magma most earthquake directly we need a volcano are caused by the movement of magma
Volcanoes
Volcanoes only occur at convergent and divergent plate boundaries. At convergent boundaries, one plate is forced below the other, forming a ridge along which mountains and volcanoes develop. Huge forces are exerted as the plates meet. This causes cracks to occur in the crust, which are filled by magma escaping from the mantle, ultimately producing a volcano, as described by BBC Bitesize. In contrast, the plates moving in opposite directions at divergent boundaries cause the crust to break apart, leaving a gap. This gap is filled by magma, forming new crust at the boundary, according to Classroom of the Future. Volcanoes are formed where this magma reaches the surface. When pressure within volcanoes builds up to a certain level, they erupt, spewing molten magma and debris over the surrounding areas.
Earthquakes
According to an article by BBC News in 2009, earthquakes are among the most destructive natural events. Earthquakes are not a geological structure like volcanoes and they do not release magma. They are violent movements of the Earth's crust. However, unlike volcanoes, earthquakes are common to all types of plate boundary. Earthquakes occur as a result of friction and build up of pressure between plates. They can take place when moving plates collide or when they become locked together. At transform boundaries, for example, plates moving side by side may become locked together, and the pressure (potential energy) will build up. Eventually the plates break free, releasing the stored energy in the form of an earthquake.
