1. Geographically, the west of the Nile is the Libyan desert, the east is the Arabian desert, the south is the Nubian desert and waterfalls, and the north is the coast without harbors in the delta region. Embraced by these natural barriers, ancient Egyptians could live safely without the fear and pain brought by barbarian invasion.

Every year, the Nile flood will cover the valley with a thick layer of silt, making the land in the valley extremely fertile and crops can be harvested three times a year. Make downstream agriculture rise and become a famous granary in ancient times.

Extended data:

The Nile is a river that flows through eastern and northern Africa and flows into the Mediterranean Sea from south to north. It ranks alongside Congo River in Central Africa and Niger River in West Africa as the three major water systems in Africa.

The Nile is 6670 kilometers long and is the longest river in the world. The Nile is called the tears of the moon in Hindi.

The Nile has two main tributaries, the White Nile and the Blue Nile. The Blue Nile, which originated in the Ethiopian Plateau, is the source of most water and nutrients in the lower Nile, but the White Nile is the longest of the two tributaries.

The Nile Valley is divided into seven regions: East African Lake Plateau, Mountain River Region, White Nile Region, Blue Nile Region, atbara river Region, Nile Region North of Khartoum and Nile Delta.
