Libya, officially the Socialist People's Libyan Arab Great Jamahiriya, SPLAGJ, is a country located in North Africa. Bordering the Mediterranean Sea to the north, Libya lies between Egypt to the east, Sudan to the southeast, Chad and Niger to the south, and Algeria and Tunisia to the west. With an area of almost 1.8 million square kilometres (700,000 sq mi), 90% of which is desert, Libya is the fourth largest country in Africa by area, and the 17th largest in the world.The capital, Tripoli, is home to 1.7 million of Libya's 5.7 million people.

The three traditional parts of the country are Tripolitania, the Fezzan and Cyrenaica. The climate is mostly dry and desertlike in nature. However, the northern regions enjoy a milder Mediterranean climate. Natural hazards come in the form of hot, dry, dust-laden sirocco (known in Libya as the gibli). This is a southern wind blowing from one to four days in spring and autumn. There are also dust storms and sandstorms. Oases can also be found scattered throughout Libya, the most important of which are Ghadames and Kufra.

The Libyan Desert, which covers much of eastern Libya, is one of the most arid places on earth. In places, decades may pass without rain, and even in the highlands rainfall happens erratically, once every 5–10 years. At Uweinat, the last recorded rainfall was in September 1998. There is a large depression, the Qattara Depression, just to the south of the northernmost scarp, with Siwa oasis at its western extremity. The depression continues in a shallower form west, to the oases of Jaghbub and Jalo. Likewise, the temperature in the Libyan desert can be extreme; in 1922, the town of Al 'Aziziyah, which is located Southwest of Tripoli, recorded an air temperature of 57.8 °C (136.0 °F), generally accepted as the highest recorded naturally occurring air temperature reached on Earth.

There are a few scattered uninhabited small oases, usually linked to the major depressions, where water can be found by digging to a few feet in depth. In the west there is a widely dispersed group of oases in unconnected shallow depressions, the Kufra group, consisting of Tazerbo, Rebianae and Kufra. Aside from the scarps, the general flatness is only interrupted by a series of plateaus and massifs near the centre of the Libyan Desert, around the convergence of the Egyptian-Sudanese-Libyan Borders. Slightly further to the south are the massifs of Arkenu, Uweinat and Kissu. These granite mountains are very ancient, having formed long before the sandstones surrounding them. Arkenu and Western Uweinat are ring complexes very similar to those in the Aïr Mountains. Eastern Uweinat (the highest point in the Libyan Desert) is a raised sandstone plateau adjacent to the granite part further west.The plain to the north of Uweinat is dotted with eroded volcanic features.
