Plot the moving continents

'The Earth time jigsaw puzzle; plot the moving continents, from the past to the future'.

Research has shown that pupils and other people can have great difficulty visualising the great lengths of geological time. This activity has been devised to help them to think in hundreds of millions of years and to picture the steady movement of continents over the expanse of geological time.
Note, the area shown in red on the maps shows part of the micro-continent of Avalonia on which England and Wales formed and of part of the Laurentian plate containing Scotland.
Many activities about moving continents and plate tectonics can be found on our website.

Why are big earthquakes so much more destructive than small ones?

Today we are publishing our 300th Earthlearningidea!
'Spaghetti quakes; why are big earthquakes so much more destructive than small ones?


This activity uses increasingly large bundles of dry spaghetti to demonstrate how each unit of logarithmic increase in earthquake magnitude is related to a 30-fold increase in energy release. It's a demonstration of “earthquake energy” using spaghetti, to help students to appreciate the use of logarithmic scales when measuring quantities with huge ranges in values. And it's fun!
Many more earthquake related activities can be found on our website by using the search engine or the alphabetical index.
