Malta is an archipelago in the central Mediterranean (in its eastern basin), some 80 km (50 mi) south of the Italian island of Sicily across the Malta Channel. Only the three largest islands – Malta (Malta), Gozo (Għawdex) and Comino (Kemmuna) – are inhabited. The smaller islands are uninhabited. The islands of the archipelago lie on the Malta plateau, a shallow shelf formed from the high points of a land bridge between Sicily and North Africa that became isolated as sea levels rose after the last Ice Age. The archipelago is therefore situated in the zone between the Eurasian and African tectonic plates.
Numerous bays along the indented coastline of the islands provide good harbours. The landscape consists of low hills with terraced fields. The highest point in Malta is Ta’ Dmejrek, at 253 m (830 ft), near Dingli. Although there are some small rivers at times of high rainfall, there are no permanent rivers or lakes on Malta. However, some watercourses have fresh water running all year round at Baħrija nearRas ir-Raħeb, at l-Imtaħleb and San Martin, and at Lunzjata Valley in Gozo.
Phytogeographically, Malta belongs to the Liguro-Tyrrhenian province of the Mediterranean Region within the Boreal Kingdom. According to the WWF, the territory of Malta belongs to the ecoregion of “Mediterranean Forests, Woodlands and Scrub.
