## Iran

The Lut Desert has recorded the highest land surface temperatures ever measured from orbit, around 80 °C. Iran is largely a high plateau ringed by mountains — the Zagros and the Alborz, where Damavand reaches 5,610 m, the highest volcano in Asia. The qanat, an underground irrigation tunnel, has been used here for around 3,000 years.

## United Kingdom

Made up of Great Britain, the north-east of Ireland and around 6,000 smaller islands. No point in the UK is more than about 113 km from the sea. Ben Nevis, the highest point, is 1,345 m, which is modest — but the country has around 31,000 km of coastline once every inlet is counted.
