The Arabian sea.
The Arabian Peninsula is located in the northern hemisphere. It spans across Southwest Asia and Northeast Africa.
The Arabian Peninsula is 1,200 miles on the side bordering the Red Sea. It is 1,300 miles across at the widest point. The total area of the peninsula is about 1,200,000 square miles.
Many cities on the Arabian Peninsula were trading centers. Mecca (Makkah) and Medina were major centers on the peninsula proper. On the edges were Baghdad, Cairo, and Alexandria (much of Iraq lies on the geographical boundary of the peninsula). Cities in present-day Yemen and Oman traded across the Indian ocean with mainland Asia.
The Arabian Peninsula experiences varying levels of rainfall across different regions. The average annual rainfall in most parts of the peninsula is low, ranging from less than 100 mm to around 250 mm. However, some highland areas can receive higher amounts of rainfall, particularly in southwestern regions like Yemen and parts of Saudi Arabia. Generally, the Arabian Peninsula is characterized by arid to semi-arid conditions with limited precipitation.

Mauritania is in northwest Africa, but Saudi Arabia is on the Arabian Peninsula in Asia, just across the Red Sea from the northeast coast of Africa.

The trade would either be by using boats to cross the Red Sea or, more commonly, using a caravan of camels to cross from Egypt to the Arabian Peninsula via the Sinai Peninsula.
Arabs survived on the Arabian Peninsula primarily as nomadic pastoralists, meaning that they raised sheep and goats and moved across the Arabian Peninsula in search of grass to graze. They would usually find increased greenery at one of the many oases on the Arabian Peninsula. Eventually, Arabs created cities that could effectively trade local wealth and products for foreign foodstuffs from breadbaskets like Mesopotamia or Egypt.
the exotic rivers. those are rivers that begin in humid regions and then flow across dry areas in Arabian Peninsula
Early humans likely migrated out of Africa along routes that followed natural landforms and resources, such as rivers and coastlines. They may have traveled north through the Sinai Peninsula into the Middle East, or along the coastal routes of the Red Sea and into southern Europe. Additionally, some groups may have moved southward through the Arabian Peninsula or across the Bab el Mandeb Strait to reach the Arabian Peninsula and beyond. These paths would have provided access to food and water, facilitating their spread across the globe.
