Papua new guinea earthquake 2018

WALT:Describe recent earthquakes

Today I found out that one of our pacific islands got hit by a  7.5 magnitude earth quake.Also it hit the ring of fire the ring of fire is where the two plates always clash into each other to create natural distastes.The effects of this is that lots of building are busted done and some people are hurt.To describe how it happened we used bread and nutella and jam so we spread nutella on to a thin layer of the bread and cut it in half after that we put some jam between the pieces of bread and squish them together.The jam was for the mantel to see how it happens and the nutella was for the crust and I learnt that some of the tectonic plates slide under to make earthquakes and also slide against each other which create natural distastes.

Continental Drift

Today in science class Mrs wells

showed us what continental drifting is and how it happened which
was pretty cool to learn.When Mrs wells put the food colouring in the

food colouring started to rise slowly up and some of it went down.

The reason why it did that is because the water was hot

which made it bubble up at the bottom and rise to the top

which made the colour spread around also let the green

into it so it can rise to the top.Also their is no space left because

the water covers it all so their is no space.When it cools down it goes

to the bottom then rise to the top again.

The cups of water represents the heat from the bottom that makes the

food colouring rise.

What I learnt about it is that the outer core heats up to the mantel

which makes it heavy then it travels for miles and get’s

cool down which makes it lighter then sinks back down.

Earth Layers

WALT:Describe the layer's of the earth

In our science class we are learning about the layers of earth which is Inner core , Outer core , mantel and crust.

The outer core of the earth liquids layer about 2,260 km compose with nickle and iron which lies above the earth solid inner core and below it's mantel.

The Crust is the outside of the earth in geology , a crust is the outermost layer of a plant the crust if the if the earth is like the crust of bread and pizza also it is composed of a great variety of igneous , metamorphic , and sedimentary rocks.Also the crust is under our feet.

The inner core is the earth's innermost part.it is primarily  a solid ball a radius of about 1,220 km (760 miles) , which is 70% of the moons radius.The inner core is in the centre of the earth which is like lava down their.

The mantle is just below the crust.The interior of earth , similar to the other terrestrial planet's , is divide into the layer of different composition.The mantel is a layer between the crust and outer core.

The yellow is inner core , the orange is the outer core , the green is the mantel , and the brown is the crust.
