Earth's structure. Cutaway computer illustration of the internal structure of the Earth. The inner Earth is divided into several distinct layers. The top layer,the crust that forms the land and underlies the seas. Below around 4 kilometres down (at 110 degrees Celsius),no more life is found. The next layer is the upper mantle,on which the crust floats. Two more mantle layers are found below this,consisting of molten rock between 1500 and 3000 degrees Celsius. Around half way to the centre of the Earth is the outer core (inside brown shell) of liquid iron and nickel,overlying the solid inner core of mainly iron | |
