mountains along iran's border with iraq and the persian gulf
Geography of Iran The topography of Iran consists of rugged, mountainous rims surrounding high interior basins. The main mountain chain is the Zagros Mountains, a series of parallel ridges interspersed with plains that bisect the country from northwest to southeast. Many peaks in the Zagros exceed 3,000 metres (9,843 ft) above sea level, and in the south-central region of the country there are at least five peaks that are over 4,000 metres (13,123 ft).
Arabian Peninsula The Arabian Peninsula is located in the continent of Asia and bounded by (clockwise) the Arabian Gulf on the northeast, the Strait of Hormuz and the Gulf of Oman on the east, the Arabian Sea on the southeast and south, the Gulf of Aden on the south, the Bab-el-Mandeb strait on the southwest and the Red Sea, which is located on the southwest and west.[12] The northern portion of the peninsula merges with the Syrian Desert with no clear border line, although the northern boundary of the Arabian Peninsula is generally considered to be the northern borders of Saudi Arabia and Kuwait.[12]
