Behind the Bushehr inspections: Iran's seas, its mountains and the strait at its mouth

Background

IAEA inspectors are at work at the Bushehr nuclear power plant, which stands on Iran's southern coast; this item sets out the geography around it.
That southern coast fronts the Persian Gulf, and the Gulf of Oman lies beyond it to the south-east.
The Strait of Hormuz joins the Persian Gulf to the Gulf of Oman and is the narrow exit for much of the region's oil.
In the north Iran has a coast on the Caspian Sea, the largest inland water body in the world.
The Zagros range runs down the country's west and south-west, and the Alborz range curves along the north, with Mount Damavand its highest point.
The Dasht-e Kavir and the Dasht-e Lut are the two great deserts of the interior, and Lake Urmia lies in the north-west.
Iran is a member of the Organization of the Petroleum Exporting Countries, and its currency is the rial.
