Volcanoes

Walt: to write explanation writings.I did my piece of explanation writing on volcanoes


Volcanoes


Volcanoes are a mountain or hill, Typically conical having a crater or vent through which lava, rock fragments and gas are or have been erupted from. Volcanoes are found along tectonic plates, erupt and there have been many famous eruptions throughout the years.

Volcanoes are found along tectonic plates. The volcanoes form when the tectonic plates collide and one of the plates end up moving/get pushed under the other which produces the volcanoes. The hot magma will rise from the mantle at the mid-ocean ridges which push the plates apart. The molten rock then rises up and erupts on the surface which builds up a volcano.

what the volcano eruption is it can also be very destructive and dangerous.

Throughout the years there have been many eruptions around the world. The worst volcano eruption ever was the Mount Tambora explosion that was in Indonesia on the 10th of April in 1815. This volcano erupted for more than 50 cubic kilometres of magma. There have been many other volcano explosions like Mount Krakatoa or Mount Ruiz.


In conclusion There have been lots and lots of volcano explosions throughout the years. And they can cause lots of damage.





Have you ever wanted to know how volcanoes erupt? Volcanoes erupt when molten rock which is magma rises to the surface. The magma is formed when the earth mantle melts. If the magma is thick the gas bubbles can not easily escape and the pressure will build up as the magma rises. When the pressure is too much an explosive eruption that is

  1. Kia ora Aoife, Volcanoes are an interesting topic to research and you have shared some key scientific facts about them. Do you know about volcanoes in Aotearoa? There are a few still active in our country and lots to research.
