Key Words: Structure; Core; Mantle; Crust; Seismic waves

Aims- To name and describe the three zones of the Earth

           To use our reasoning to ask some questions to help us understand the zones of the Earth

To think about:

 

What is the deepest place humans have ever reached? (How can you tell how deep you have reached?)

Could we ever drill a hole to the centre of the Earth?

Assuming you could, where on the earth’s surface  would you begin?

 

As you dug through, what would you come across?

What evidence is there that the Earth is not just a solid lump of rock spinning through space?
