Answer:The Arabian Peninsula is a large land bridge suspended between Africa and Asia. It is among the largest peninsulas on earth, and is surrounded by water on all four sides. To the north lies the Mediterranean Sea and to the west lies the Red Sea. To the east is the Persian (or Arabian) Gulf, and to the south is the Arabian Sea, which is also part of the Indian Ocean.
About three-quarters of the Arabian Peninsula is covered by deserts. Geographers think that the region had changed from savannah, or grasslands to desert by about 8,000 B.C.E., along with the neighboring Sahara Desert in North Africa. Artifacts from hunter-gatherer groups and early settled cultures have been found at many sites. Traces of the earliest towns, cities and civilizations in the Fertile Crescent along the Mediterranean Sea have also been found. The Arabian Peninsula is mostly arid with inhospitable terrain and fertile regions nearly all around the periphery. Along the mountainous Arabian Sea coast to the south, rain-fed and irrigated highland areas support a rich agriculture. These mountains continue up to the Red Sea coast, but they do not receive the monsoon rains, and are mostly arid.
