Volcano Report

How does a volcano erupt ?

Underneath the earths crust the pressure of the magma builds up. It then is forced up and it makes a vent in the earths surface. After it has erupted the lava then dries up and forms a mountain .

About volcanoes .

Volcanoes are mountains that erupt. It is a vent in the earths crust through which magma and gasses erupt. The word volcano comes from the god of fire, Vulcan. Volcanoes are all over the world. Most volcanoes are on the edge of the tectonic plates .

3 different typ of volcanoes

The shield volcano got its name because people thought it looked like the shape of an ancient warriors shield. The shield volcano is low in silica. They are shallow sided and have a flat bottomed crater. It has a long fluid lava flow which can also flow into sea. Shield volcanoes can also be found on the ocean crust.

The stratovolcanoes are the most famous volcanoes. Mount St. Helens, Mt Vesuvius and Mt Fuji are all stratovolcanoes. When they start to erupt it begins with an explosion of ash and cinders. These volcanoes are often found on subduction zones.

Cinder cone volcanoes are the smallest volcanoes.
These volcanoes are formed by low silica magma that is runny. They are steep sided volcanoes that are cone shaped.

What is the biggest volcano in Auckland ?

The biggest volcano in Auckland is Rangitoto . Rangitoto is one of the youngest volcanoes
but this volcano has the most violent eruption when it occured it last eupted 600 years ago to 800 years . Rangitoto was named after a woman whose name is Te RangiTotongia

Don't we look GREAT in our new uniform.
As our Aces team heads along to the courts , first we had to take a team photo . After that we all got sorted then headed off to the netball courts . When we arrived we went for a jog around the the courts then had to do 4 side steps to the line then come back . My position was CENTER then I will have to change to WA in the next half then it was time to play so we stretched first and drank water.
As our game was about to start it was our ball first ! The ball come down to our shooters our team got the first point
. Then the game became harder because the other team had more point so then our team went hard on them so then we were in the lead it was nearly half time so we threw the ball back to the shooter then had the last goal !!
My position was CENTER I was so happy because center is a good exciting position for me because I can run around and get the ball straight to the goal . The game was nearly over and our team were winning !
The bell went ` Brinnnng ! and the ACESS WON !! .

My sister screamed Ya YA it was a point to the MYSTICS !! . the bell went ` Brinng the game was over and the Mystics WON !! .

Auckland volcanic field

The Auckland volcanic field is made up of 48 basalt . This Auckland volcanic field was formed
because there was a huge hot spot . Mt wellington , Rangitoto were both the youngest volcano but Ranigtoto was the biggest eruption . The Auckland volcanic field is very young with the first eruption occuring around 250,00 years ago . It is the a big massive hot spot in geological
terms the Auckland volcanic filed is very young .



Rangitoto is one of the youngest volcanoes in Auckland . It has probably erupted twice and Scientists believe that it is extinct. Rangitoto was formed through a violent eruption
about 600 years ago and was one of the most violent eruption in Auckland. Rangitoto was named after a women whose name was Te Rangi Totongia which was a beautiful name that's how they came up with Rangitoto . It had erupted 600 years ago which makes it the youngest of all of the volcanoes in the Auckland Volcanic field.

Rangitoto was the only eruption to be witnessed by man.
