How thin is the crust we live on?

You can answer the question 'Just how thin is the crust we live on?' by trying this Earthlearningidea - 'Journey to the centre of the Earth - on a toilet roll'

We seldom stop to consider the true scale of many features of the Earth. This activity aims to enable pupils to visualise the thickness of the crust in relation to the rest of the Earth. It also helps them to appreciate the difference in depth between the oceanic crust and the continental crust. It introduces the terms ‘lithosphere’ and ‘asthenosphere’ to help in understanding plate tectonic theory.
Many more activities about the structure of the Earth and about plate tectonics can be found on our website.
