How did the physical geographic characteristics of Egypt affect the development of their civilization?
The Nile River made existence for a large population possible in a desert region. Every year, the Nile would flood, bringing rich soil to the lower reaches of the river course. This allowed agriculture to flourish, as well as dictating when planting and harvesting would occur. Because the delta area produced surplus crops on a regular basis, the society in that area was fairly stable, and had leisure time for developing art and science. Answer You also have to consider the effect that having access to large quantities of stone, especially granite, had on Egypt. This began the building of the pyramids and other large structures out of stone instead of red mud bricks.
Answer There is also a theorie, that the ancient Egyptians saw the Nile as a reflection of the Milky Way and made the pyramids of Ghiza to reflect the three stars in the belt of Orion. The physical geographic characteristics of Egypt created an astral religion and a big part of the rest of Egypt's culture and the development of their civilization.
