Final answer:
The Nile River is the main geographic feature that influenced the location of Egypt's civilization.
Step-by-step explanation:
The main geographic feature that influenced the location of Egypt's civilization is the Nile River. The ancient Egyptians relied on the Nile for their survival as it provided them with fertile soil for agriculture and a source of water for drinking, bathing, and irrigation.
The annual flooding of the Nile deposited nutrient-rich silt, creating a fertile floodplain which allowed the Egyptians to cultivate crops such as wheat, barley, and flax. This abundance of food allowed the civilization to prosper and develop.
Additionally, the Nile served as a natural transportation route, facilitating trade and communication between different regions of Egypt. It connected the Upper Nile region in the south to the Nile Delta in the north, enabling the Egyptians to establish a unified and flourishing civilization.
