THE CAUSE OF VOLCANO ERUPTION

The Cause of Volcano Eruption

The earth has “plates” and when two plates hit each other, one goes under and becomes “molten” that means it gets so hot, the ground turns into liquid. The molten stuff finds a hole in the ground and comes out the top. All of the continents used to be just one big piece of land, but the land broke up and floated away and created the 7 continents we have now. This was called continental drift. If you look at South America, it looks like it could fit like a puzzle piece into Africa.

Because of the way the ground broke, it created plates. Even though the ground is heavy, the plates continue to move and that can cause earthquakes and volcanoes. When two plates hit each other, one can go under and become “molten” which means it gets so hot, the ground turns into liquid. The molten stuff finds a hole in the ground and comes out the top. When the molten stuff is in the volcano it is called magma. When it explodes, it is called lava.

Volcanoes explode because of the gas buildup. When the gas builds up a lot, the gas and lava, which is hot rocks, blows out the top, it’s a lot like the way a soda explodes. The lava can get up to 1600 degrees - a lot hotter than an oven. After the lava cools, it turns into rock. One of the types of rock is obsidian, which is shiny and black. Volcanoes can also occur on other planets. Not all volcanoes explode, some are inactive and some are dormant.

Lots of volcanoes happen in the “Ring of Fire” which is from California to Asia. There are large tectonic plates in the Ring of Fire and lots of earthquakes happen here too.

So the causes of the volcano eruption are:

1. Increased volcanic seismicity.
2. Increased temperatures crater.
3. Increasing waves of magnetism and electricity, to the deformation of the body mounts.
4. Earth plates jostle each other and magma in the earth's crust is urging and encouraging the earth's surface and trigger geological activity, volcanic, and tectonic.
5. Due to the very high pressure, the magma pushes out (eruption) of the earth's surface as lava.
