Do you know why a soda bottle fizzes and pops when you open it? Because it has a lot of pressure inside it. And so does the Earth!
When our planet was first formed, it was a huge ball of hot thick liquid (like the lava) that slowly cooled down over millions of years forming several layers. But the centre of it still remains molten – liquid, but more like playdough – because of the nuclear reactions that continue to take place.
Scientists have been able to study the different layers by studying the other planets, pieces of meteorites that have fallen on Earth, and by drilling holes deep into the ground. Natural phenomena like earthquakes and volcanic eruptions are a result of the pressure inside Earth and the interaction between the different layers.
Below is a representation of the different layers of Earth and how they are stacked. Can you guess the names of the each layer and drag and drop into the correct boxes?
