Iran has a variable climate. In the northwest, winters are cold with heavy snowfall and subfreezing temperatures during December and January.
There is a vastly extended network of rivers in Iran most of which seasonally are filled with water. Some permanent rivers run from the Alborz or the Zagros to the Caspian Sea, Persian Gulf and Oman Sea.
The currency in Iran, or the money used, is called the rial (pronounced ‘reeyaal’). The rial is like the dollar or a pound in that is made up of 100 pieces, in Iran called dinars. However, due to high inflation one riyal is worth so little that no fraction of it is really used on a day to day basis.
