Modelling the state of 'balance' of the Earth's outer layers - isostasy

Today's new ELI is 'Isostasy 1; modelling the state of 'balance' of the Earth's outer layers'. Isostasy is essentially the principle of hydrostatic equilibrium applied to the Earth, otherwise called ‘buoyancy’. You can model this principle using wooden blocks floating in water and in a denser medium.

Lots of activities about the structure of the Earth can be found on our website.
