beacuse of its geography egypt/kush needed grain

Egypt and Kush needed grain because of their geographical location and climate. Both regions were located in the arid and desert landscapes of northeastern Africa, where agriculture was challenging due to the lack of rainfall and fertile soil. As a result, these civilizations relied heavily on the annual flooding of the Nile River, known as the Nile inundation.

The Nile inundation brought rich silt and water to the surrounding areas, creating fertile land suitable for agriculture. Egyptians and Kushites developed sophisticated irrigation systems and employed farming techniques to cultivate crops, particularly grains like wheat and barley. These grains formed the staple diet of the ancient Egyptians and Kushites, providing them with sustenance and nourishment.

Moreover, both Egypt and Kush were situated in close proximity to each other, allowing for trade and exchange of goods. Egypt, with its advanced agricultural techniques, was often referred to as the "breadbasket of the ancient world." It produced surplus grain, which it could trade with neighboring regions like Kush in exchange for resources such as gold, ivory, and other valuable commodities.

Thus, the geography of Egypt and Kush, specifically the presence of the Nile River, played a crucial role in their need for grain as it supported their agricultural practices and facilitated trade.
