Science Layers of the earth
This term were were learning about layers of the earth and i have learnt about the layers.There are 4 layers of the earth the first layer is the earths crust The Earth’s crust is the outermost layer of our planet and is less than 1% of the entire Earth's size. There is the crust and then the mantle and they both contain different kinds of rocks which make them different to each
other.
The second layer is the mantle The mantle is made up of mafic and ultramafic rock. These are rocks made largely of iron and magnesium, and mafic is a portmanteau of the words "magnesium" and "ferric." The rock in the mantle is very hot and can be viscous or molten depending on the temperature and the pressure.
The third layer is the outer core The Outer Core is the second to last layer of the Earth. It is a magma like liquid layer that surrounds the Inner Core and creates Earth's magnetic field. In this section you will learn about how Earth's magnetic field is created, how hot it is, how thick the Outer Core is and a few interesting facts about the Outer Core.
The last layer of earth is the inner core The Inner Core is the final layer of the Earth. It is a solid ball made of metal. To learn about what metal the Inner Core is made of, read this section about the Inner Core. You can also learn how hot the Inner Core is, how thick it is and some interesting facts about the Inner Core.
