The organisers of the transatlantic contest are the UK-based Give Geography its Place Campaign. Anyone from the UK or the USA with access to a computer can take part by visiting www.geography cup.com until December 31.
The final national score will be a percentage based on the number of people who have taken part. There will also be a leader board for each country so members will be able to see who has come out top within their own country.
