Final answer:
Upper Egypt was located south of Lower Egypt due to the higher elevation in the south and the flow of the Nile River.
Step-by-step explanation:
Upper Egypt was located south of Lower Egypt because of the higher elevation in the south. The Nile River, which flows northward, originates from the highlands of East Africa and descends to lower elevations in Lower Egypt. As a result, Lower Egypt is located closer to the Mediterranean Sea, while Upper Egypt is situated further inland, towards the south.
