Good Morning

     Have you ever wondered what it would be like to be on a mountain that was as hot as the sun?  Well, if you were standing on a volcano that was pouring out lava, that’s what it would be like.

     Volcanoes are so amazing!  You can find volcanoes all over the world even under the sea.  But so far they have never found any in Canada.

     A volcano starts deep in the earth.  Inside the earth the rock is very soft and it is called magma.  When the magma gets too hot it explodes out of the earth and now it is called lava.

     There are different kinds of lava.  A small piece of lava that goes into the air is called volcanic dust.  If the lava is smaller than an apple, it is called volcanic ash.  But if the pieces are larger than an apple they are called volcanic bombs.

    Some volcanic dust has been pushed up as high as 17 miles into the air.  That’s high!

    Volcanic bombs have enough power to blast through the roof of a house.

    Lava is very dangerous.  It can kill people!  The only way to get near lava is by wearing a special suit.  Volcanologists wear the suits when they are studying volcanoes.

    Do you know what a volcanologist is?  Volcanologists study volcanoes so that they can predict eruptions.  They use special equipment like a seismograph to measure the tremors of a volcano.

    Before an eruption, the magma builds up inside the volcano and the volcano starts to shake.  The Volcanologists study this and sometimes they can predict an eruption weeks a head of time.

    Lava takes a long time to cool.  Sometimes even years!

    Something else that is interesting, is that volcanos can be covered with snow or ice and when they erupt they can cause a mudslide.

    The Mauna Loa volcano in Hawaii is the largest volcano in the world and the Stomboli volcano in Italy erupts every 20 minutes.

    Wow!  Can you imagine living near a volcano that erupts every 20 minutes?  I think I would move!

    Most volcanoes erupt for 3 or 4 weeks and then they rest, but some erupt for many years, like the Stomboli volcano.

    New volcanoes are always forming under the sea, but no one knows they are there until they erupt.

    Volcanoes are very noisy when they erupt.  Noisier than a jet!  Sometimes a big boom from a volcano can be heard hundreds of miles away.

    There are some good things about volcanoes. 

    The dust from volcanoes can be good fertilizer to help plants grow better and faster and that is why some people like to live near them.

    But I think I still like living in Canada where there are no volcanoes…Yet!

     

    Thank you.
