Lahars

Kia ora

Today we built Mt Ruapehu in the sandpit. We also made the Whangaehu River valley, the plain below the mountain and the railway bridge at Tangiwai. We wanted to learn how the lahar destroyed the bridge in 1953 causing the Tangiwai Disaster. Kora and Ariana poured lots of water into the crater we had made on top of our mountain. It whoosed down the side of the mountain and into the river valley. The bridge collapsed and bits of our train fell into the river. After that, we watched a short video about what do do if you are on Mt Ruapehu when the lahar siren sounds.  Now I know how to keep safe from a lahar if one happens when I am on a mountain.  Here is my Hazard Notice with the most important information.

Structure Of The Earth

Structure of the Earth Facts

We are learning about the structure of the Earth.

I learnt that the Earth is made up of 4 layers. They are the; crust,mantle,outer core and the inner core.

Facts about each layer:

Crust -the crust is the thinnest layer on the Earth at 8-40 km thick and it is the coldest layer of the Earth

Mantle - the mantle is the thickest layer of the Earth and it has lots of lava and it takes up 84% of Earth's total volume.

Outer Core - the outer core is the only liquid layer and as the Earth spins around it spins around the melted iron and nickel moves around.

Inner Core - the inner core is really hot but it is solid because the pressure from the earth pushed onto is and makes it a solid iron and nickel ball.

Our group -  Jaxon,Maximus,Kane

First we created a 3D image of the earth using clay, knife, and news paper.

We then cut the shape in half to show the different layers. After waiting for it to dry, we identified each layer by painting them in different colours.

Below are some pictures of our work.
