Geography & Climate
|
Iran is the eighteenth largest country in the world, with an area of 1,648,000 km2 (636,000 sq mi). Its area roughly equals that of the United Kingdom, France, Spain, and Germany combined, or somewhat more than the US state of Alaska. Its borders are with Azerbaijan (432 km/268 mi) and Armenia (35 km/22 mi) to the north-west; the Caspian Sea to the north; Turkmenistan (992 km/616 mi) to the north-east; Pakistan (909 km/565 mi) and Afghanistan (936 km/582 mi) to the east; Turkey (499 km/310 mi) and Iraq (1,458 km/906 mi) to the west; and finally the waters of the Persian Gulf and the Gulf of Oman to the south.
Iran consists of the Iranian Plateau with the exception of the coasts of the Caspian Sea and Khuzestan. It is one of the world's most mountainous countries, its landscape dominated by rugged mountain ranges that separate various basins or plateau from one another. The populous western part is the most mountainous, with ranges such as the Caucasus, Zagros and Alborz Mountains; the last contains Iran's highest point, Mount Damavand at 5,610 m (18,405 ft), which is not only the country's highest peak but also the highest mountain on the Eurasian landmass west of the Hindu Kush.
The Northern part of Iran is covered by dense rain forests called Shomal or the Jungles of Iran. The eastern part consists mostly of desert basins such as the Dasht-e Kavir, Iran's largest desert, in the north-central portion of the country, and the Dasht-e Lut, in the east, as well as some salt lakes. This is because the mountain ranges are too high for rain clouds to reach these regions. The only large plains are found along the coast of the Caspian Sea and at the northern end of the Persian Gulf, where Iran borders the mouth of the Shatt al-Arab (or the Arvand Rūd) river. Smaller, discontinuous plains are found along the remaining coast of the Persian Gulf, the Strait of Hormuz and the Sea of Oman.
Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 °C (85 °F). Annual precipitation is 680 mm (27 in) in the eastern part of the plain and more than 1,700 mm (67 in) in the western part.
To the west, settlements in the Zagros basin experience lower temperatures, severe winters with below zero average daily temperatures and heavy snowfall. The eastern and central basins are arid, with less than 200 mm (eight in) of rain, and have occasional deserts. Average summer temperatures exceed 38 °C (100 °F). The coastal plains of the Persian Gulf and Gulf of Oman in southern Iran have mild winters, and very humid and hot summers. The annual precipitation ranges from 135 to 355 mm (five to fourteen inches).
Iran's wildlife is composed of several animal species including bears, gazelles, wild pigs, wolves, jackals, panthers, Eurasian lynx, and foxes. Domestic animals include sheep, goats, cattle, horses, water buffalo, donkeys, and camels. The pheasant, partridge, stork, eagles and falcon are also native to Iran.
Provinces and cities
Iran is divided into thirty provinces (ostān), each governed by an appointed governor (استاندار, ostāndār). The provinces are divided into counties (shahrestān), and subdivided into districts (bakhsh) and sub-districts (dehestān).
Iran has one of the highest urban growth rates in the world. From 1950 to 2002, the urban proportion of the population increased from 27% to 60%. The United Nations predicts that by 2030, 80% of the population will be urban. Most internal migrants have settled near the cities of Tehran, Isfahan, Ahvaz, and Qom. The listed populations are from the 2006/07 (1385 AP) census. Tehran, with a population of 7,705,036, is the largest city in Iran and is the Capital. Tehran is home to around 11% of Iran's population. Tehran, like many big cities, suffers from severe air pollution. It is the hub of the country's communication and transport network.
Mashhad, with a population of 2,410,800, is the second largest Iranian city and the centre of the province of Razavi Khorasan. Mashhad is one of the holiest Shi'a cities in the world as it is the site of the Imam Reza shrine. It is the centre of tourism in Iran and between 15 and 20 million pilgrims go to the Imam Reza's shrine every year.
Another major Iranian city is Isfahan (population 1,583,609), which is the capital of Isfahan Province. The Naghsh-e Jahan Square in Isfahan has been designated by UNESCO as a World Heritage Site. The city contains a wide variety of Islamic architectural sites ranging from the eleventh to the 19th century. The growth of the suburban area around the city has turned Isfahan into Iran's second most populous metropolitan area (3,430,353).
The fourth major city of Iran is Tabriz (population 1,378,935), the capital of the East Azerbaijan province. It is also the second industrial city of Iran after Tehran. Tabriz had been the second largest city in Iran until the late 1960s and one of its former capitals and residence of the crown prince under the Qajar dynasty. The city has proven extremely influential in the country’s recent history.
The fifth major city is Karaj (population 1,377,450), located in Tehran province and situated 20 km west of Tehran, at the foot of the Alborz mountains; however, the city is increasingly becoming an extension of metropolitan Tehran.
The sixth major Iranian city is Shiraz (population 1,214,808); it is the capital of Fars Province. The Elamite civilization to the west greatly influenced the area which soon came to be known as Persis. The ancient Persians were present in the region from about the 9th century BC, and became rulers of a large empire under the Achaemenid dynasty in the 6th century BC. The ruins of Persepolis and Pasargadae, two of the four capitals of the Achaemenid Empire, are located in or near Shiraz. Persepolis was the ceremonial capital of the Achaemenid Empire and is situated 70 km northeast of modern Shiraz. UNESCO declared the citadel of Persepolis as a World Heritage Site in 1979.
