Last week we made earths out of clay. We rolled an orange ball out of clay and wrapped our layers around it. The inside orange layer is the inner core. It is solid. The red layer is the outer core. It is made up of rocks and minerals and is so hot that it is liquid. The thickest layer is the mantle and it's yellow. We haven't drilled down to the mantle yet! The thinnest layer is called the crust, which we live on! Which layer is your favourite layer and why?
