Iran at a Glance
Iran combines a high interior plateau with major mountain belts and enclosed desert basins, producing strong contrasts between humid Caspian landscapes and arid interior regions.
Physical geography
terrain · drainage · setting
Iran is centered on the Iranian Plateau, framed by the Zagros Mountains in the west and southwest and the Alborz range along the southern Caspian margin. The relief focus used here is Iranian Plateau, Zagros and Alborz ranges, presented as a regional physical reference.
Regional frameSouthern Asia
SettingCoastal country
Relief focusIranian Plateau, Zagros and Alborz ranges
Climate pattern
Much of Iran is arid or semi-arid, while the Caspian lowlands are markedly more humid and mountain and desert regions create strong temperature and precipitation contrasts.
Water and landform context
Drainage is divided among the Caspian Sea, the Persian Gulf and Gulf of Oman, and extensive internal basins with no outlet to the ocean.
