The inner core is made out of solid iron.
The Outer Core
The outer core is made out of molten iron.
The Mantle
The mantle is made out of rock. The mantle is a very hot part of earth causing the liquid to behave, like liquid and solid.
The Crust
The crust is the part of the earth were most life is were we move and live. The crust is much thinner and breakable compared to other layers. The crust is 5-70km deep, depending on were you are on top of a mountain or under the ocean. the crust isn't endless all the way around the earth, it is split into pieces call tectonic plates.
Tectonic Plates
Scientists think the earth is made of 6 majorly large tectonic plate and a few more smaller ones. The plates fit like a puzzle and float on on the partially molten mantle. The slowly move and bump against each other, a few millimetres a year to up to 20 cm. It is the bumping and rubbing of the tectonic plates thet cause earthquakes and volcanoes

ReplyDeleteHi Olivia, this is a really great explanation of the Earths layers. I like that you've used subheadings to make it easier to read. The diagram is great for helping to visualise what the layers look like. Remember to reread your work to check for spelling, and that all sentences start with a capital and end with a full stop. - India
