Vicious Volcanoes

Vicious Volcanoes


Did you know that volcanoes are the Earth’s way to cool off?They act as vents through the planet’s crust and release an inside liquid metal named magma. Once the magma reaches the surface it is declared lava. Many people see the volcanoes as threats but they are completely natural.


What causes an eruption?
There are many different ways to cause volcanic activity.
Usually, they are caused by earthquakes nearby. Sometimes,
there are warning signs that a volcano is about to erupt. If not,
they could be very dangerous. The common warning signs are
either steam blowing out of the top or a low rumbling sound of
magma building up inside.


Parts Of A Volcano
There are also many parts of a volcano. Inside, there is a tube
that carries magma up to the crater called the main vent. Little
vents stream of the main vent. The crater is the bowl at the top
of the mountain and the main lava supplier. Down at the bottom
of the lava tube there is an open area called the magma chamber.


Maori Connection
Millions of years ago, the New Zealand’s Mt. Ruapehu exploded
while creating a lake into Lake Taupo. One of the worst disasters
happened in Tangiwai, or Weeping Waters. When lava mixes with
a mud or water, it turns into a thick mud called lahar. This caused
the train bridge to be swept away and a christmas locomotive
bailed over the edge.


How to Survive It
Usually, there are warning signals that a volcano is about to erupt.
Use this as an advantage and leave the area immediately. If your
city government tells you to leave, then do so.


Trivia

Lava can reach 1,250℃ (2288℉) and 64 kph (40mph)

Shield volcanoes are another type of volcano which looks like a
shield and just spews out lava instead of an explosion.

  1. I like how you made your sub headings obvious they were the subheadings, by making them sloped.
