- The Strait of Hormuz (/hɔːrˈmuːz/ Persian: تنگهٔ هُرمُز Tangeh-ye Hormoz listen, Arabic: مَضيق هُرمُز Maḍīq Hurmuz) is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world’s most strategically important choke points. On the north coast lies Iran, and on the south coast lies the Musandam peninsula, shared by the United Arab Emirates and the Musandam Governorate, an exclave of Oman. The strait is about 90 nautical miles (167 km) long, with a width varying from about 52 nmi (96 km) to 21 nmi (39 km).
- Carbon (Wikipedia)
Carbon (from Latin carbo ‘coal’) is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth’s crust. Three isotopes occur naturally, 12C and 13C being stable, while 14C is a radionuclide, decaying with a half-life of 5,700 years. Carbon is one of the few elements known since antiquity.
