Final answer:
The ancient Egyptians referred to the southern region of Egypt as 'Upper Egypt' because it was located upstream of the Nile river.
Step-by-step explanation:
The ancient Egyptians referred to the southern region of Egypt as 'Upper Egypt,' which is the opposite of what we might think. This is because the Nile River flows from the south to the north, so the upper part of Egypt was actually in the south. The name 'Upper Egypt' originated from the Nile's elevation, as the river flows downhill from the African highlands in the south to the Mediterranean Sea in the north.
