Answer 1

Additionally, the cataracts of the Nile River in the south posed a challenge to invaders trying to navigate the river, as well as the marshy areas in the Nile Delta that made it difficult for armies to easily invade from the north. Furthermore, the natural barriers provided by the Red Sea to the east and the Mediterranean Sea to the north also helped protect Egypt from invasions by sea. Overall, Egypt's natural borders made it challenging for invaders to penetrate and conquer the country.
