Savannah vs Alexandria

Informations

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800–3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha.

Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season; they are associated with several types of biomes, and are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area.

Alexandria ( or ; Arabic: الإسكندرية‎ al-ʾIskandariyya; Egyptian Arabic: اسكندرية‎ Eskendereyya; Coptic: ⲣⲁⲕⲟϯ Rakodī; Greek: Αλεξάνδρεια Alexandria) is the second-largest city in Egypt and a major economic centre. With a population of 5,200,000, Alexandria is the largest city on the Mediterranean - also called the Bride of the Mediterranean by locals - the sixth-largest city in the Arab world and the ninth-largest in Africa. The city extends about 40 km (25 mi) at the northern coast of Egypt along the Mediterranean Sea. Alexandria is a popular tourist destination, and also an important industrial centre because of its natural gas and oil pipelines from Suez. Alexandria was founded in c. 331 BC by Alexander the Great, king of Macedon and leader of the Greek League of Corinth, during his conquest of the Achaemenid Empire. An Egyptian village named Rhacotis existed at the location and grew into the Egyptian quarter of Alexandria. Alexandria grew rapidly to become an important centre of Hellenistic civilization and remained the capital of Ptolemaic Egypt and Roman and Byzantine Egypt for almost 1,000 years, until the Muslim conquest of Egypt in AD 641, when a new capital was founded at Fustat (later absorbed into Cairo).

Hellenistic Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World; its Great Library (the largest in the ancient world); and the Necropolis, one of the Seven Wonders of the Middle Ages. Alexandria was the intellectual and cultural centre of the ancient Mediterranean world for much of the Hellenistic age and late antiquity. It was at one time the largest city in the ancient world before being eventually overtaken by Rome. The city was a major centre of early Christianity and was the centre of the Patriarchate of Alexandria, which was one of the major centres of Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage. By the time of the Arab conquest of Egypt in 641 AD, the city had already been largely plundered and lost its significance before re-emerging in the modern era. From the late 18th century, Alexandria became a major centre of the international shipping industry and one of the most important trading centres in the world, both because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea, and the lucrative trade in Egyptian cotton.
