The Strait of Hormuz is a narrow, strategically important strait between the Gulf of Oman in the southeast and the Persian Gulf. On the north coast is Iran and on the south coast is the United Arab Emirates and Musandam, an exclave of Oman. The strait at its narrowest is 54 kilometres (34 mi) wide.
Visible near the coast of Iran is Qeshm, an Iranian island situated in the Strait of Hormuz, and separated from the mainland by the Clarence Strait/Khuran in the Persian Gulf. Greenish sediments and algal growth can be observed around the island, particularly to the west.
Visible in the lower part of the image is the Musandam peninsula, jutting into the Strait of Hormuz. The Musandam peninsula is an exclave of Oman, separated from the rest of the country by the United Arab Emirates. The Musandam Peninsula has an area of 1,800 square kilometers (695 sq mi). The rugged coastline resembles the glacier-carved coasts of polar regions, but in this case, the coast was shaped by the movement of Earth’s crust. The Arabian plate is slowly pushing under the Eurasian plate, creating the earthquake-prone mountains of Iran. On the leading edge of the Arabian plate, the Musandam Peninsula is sinking. The higher elevation mountains remain above the water, but the sea has rushed in to fill the valleys with fingers of water.
