Hey there. Today we are going to be learning about Earth´s layers and tectonics. So, you see we are on the earth´s crust, and although you can´t see them, there are many other layers of the Earth.

There is the outer core then the inner core. The inner core is made up of liquid. Also, as the layers go further down, the temperature and pressure increases. Now, let´s move on!
