What Causes Volcanic Eruptions In The World?
Volcanic eruptions are caused when magma from the magma chamber of the Earth rises up the pipe and out of the vent. Magma is continuously supplied from the mantle of the Earth. Shield volcanoes usually have a gentle eruption, as it contains basic lava. Acid-lava and composite volcanoes usually have a violent eruption as it contains acidic lava. The vent of the volcano might also be blocked, causing the magma to force its way out, thus causing a huge explosion.
In a more specific way, volcanoes erupt when rock releases pressure. It spreads and creates magma and if the magma is felsic lava it will be thick and will create large eruptions but mafic lava is very watery and creates small runny explosions and it also depends what kind of volcano it is because its eruption varies upon its formation.
There are plates that are always shifting around in the ground. They move 1cm every day. When the plates collide,they make a big BOOM which cause the things in the volcano to heat up. Then the heat pushes everything to the opening in the volcano which causes it to erupt and shoot out.
No There are two main causes of earthquakes. Firstly, they can be linked to explosive volcanic eruptions; they are in fact very common in areas of volcanic activity where they either proceed or accompany eruptions. Secondly, they can be triggered by Tectonic activity associated with plate margins and faults. The majority of earthquakes world wide are of this type.
volcanic eruptions happen in Japan because the country Japan (Nippon) is situated on the plates in the Pacific and Philippines. volcanic eruptions happen in Japan because the country Japan (Nippon) is situated on the plates in the Pacific and Philippines. Well volcanic eruptions happens because the crust is made up of a huge slab of plates that fit together like a jigsaw puzzle and the plates moves which causes friction and makes the volcanoes erupt…
