## Population density

Iran is 1.6 times more densely populated than United States — 56 against 35 people per km². Density is where area and population interact, and it often reverses the impression the headline figures give — a large country with a small population can feel emptier than a small crowded one by an enormous margin.

## Practical differences

- Different currencies: the Iranian rial and the United States dollar.
- United States spans 6 time zones, so "local time" there is not a single answer.
- Different continents — Asia and North America.

## 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 States

Third or fourth largest country in the world depending on how China's area is counted. It spans six standard time zones across the fifty states, from UTC-10 in Hawaii to UTC-5 on the east coast. Death Valley holds the highest reliably recorded air temperature on Earth, 56.7 °C in 1913, and is 86 m below sea level; Denali, 5,500 km away in Alaska, is 6,190 m.
