GENERAL KNOWLEDGE

Detailed explanation-1: -The ancient Egyptians were not isolated from other cultures, but they were protected. On either side of the Nile, beyond the rich soil, was desert. Mountains rose in the south.

Detailed explanation-2: -Deserts lie on both sides of the Nile River valley. Because the deserts were so hot, the ancient Egyptians called them “the Red Land.” These areas kept outside armies away from Egypt. To the south, dangerous cataracts blocked enemy boats. In the north, the delta marshes kept enemies from sailing into Egypt.
