The Byzantine Empire was the eastern part of the Roman Empire which continued to exist for nearly 1,000 years after the fall of the western part of this empire. The educated elites of part of the empire spoke Greek because before its conquest by Rome it had been ruled by Greek states. After the fall of the western part of the empire, this part lost its ties with Rome and with the Latin language. It became increasingly Greek in character and language. It became more so when it lost most of its non-Greek territories due to invasions by the Arabs and the Slavs.
Alexander the Great.
The largest contiguous empire (the largest empire confined to a single land mass) was the Mongol Empire which, at its largest extent covered 33,000,000 sq km or 12,741,000 sq miles, some 22% of the earth's total land area. The Mongol Empire was the second largest empire after the British Empire which was a maritime empire and not confined to a single land mass. The British Empire was the largest empire in history. At it's peak the Brirish Empire covered 36.6 million km² of land and contained around a quarter of the worlds population. After World War II much of the British Empire territories declared independence. Most still retain a close relationship with Britain, some even choosing to retain the British Monarch.
There was no Greek empire. The Greek world comprised hundreds of independent city-states, which sometimes came together in temporary leagues. If you refer to Alexander the Great, the answer is Greece being next door to Asia and in particular next door to the Persian empire. Greek relations with Persia had been tense since the Persians had tried to invade Greece. Persia also held a part of Thrace on the Balkan coast, next door to Greece. Alexander's policy was war and he defeated this empire. His own empire was basically a taken over Persian empire and extended over that area, apart from an area north of the Caucasus mountain and not extending north of Afghanistan as much. This empire was so big that it was then divided between the Ptolemaic kingdom (Egypt), the Seleucid empire (the Asian possessions minus the northern coast and the eastern part of Anatolia, that is modern Turkey). the kingdom of Pergamon, the mentioned parts of Anatolia not under the Seleucids and Thrace) and Macedon (Greece minus southern Thrace and Epirus, which remained separate).
The Mughal empire occupied much of what is now India, Bangladesh, Pakistan, and Afghanistan.
Deserts, by definition, cover 14% of the earth's land area. Non-arable land, however, makes up a large percentage.
To conquer occupy and annex as much territory as they could. Building an Empire.

No one expended the Greek empire because there was not a Greek empire. Alexander the Great, the king of Macedon, with allied Greek city-states conquered the Persian Empire. After his death his generals fought each other. This resulted in the division of Alexander's conquests into the Kingdom of Pergamon, the Seleucid Empire and the Ptolemaic Kingdom.

He was Alexander the Great, not the Greek. He was a Macedonian. After his death, his empire was split and these ensuing Hellenistic (like Greek) kingdoms were taken over by his generals. After much fighting between them, this settled down to Macedonia, Egypt, Syria and Pergamon.
