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.

Rugby against the year6 boys

R U G B Y

Last week on Friday we had a match against the year 6 boys at our school. The reason why we had a match was to prepare us to play Viscount. We learnt what to do when we come in for a scrum. As soon as we got all organised it was time to play. My position was half back and wing it is scary because I am the one who gets the ball and then runs or passes. In the second half we had to change position so everyone gets a turn. The first person to get a try was me and Sela . It got boring because people were hogging the ball. The shocking part was when Sela tackled Richard ` now that was WICKED ' Woohoo go Sela' we all cheered for her. The person who tackled the most was Reina, Shaniah and Bobbi-Grace. As Mr Burt gets us together we were told that there was going to be a meeting.

We asked Mrs Nadia if she can watch us play rugby with the year7 boys. It was so cool because we were all sharing the ball and we were playing fair but then it got rough because there were people that were high tackling girls. So then Victoria and I went to play some where else.
