Write a journal entry explaining the changes you would see if you were traveling down the Nile from the source to the Delta.

The Nile River of Africa is the longest river in the world, covering a distance of more than 4,000 miles. Beginning near the equator, the river flows northward through northeastern Africa and passes through Egypt before emptying into the Mediterranean Sea. The Nile River was extremely important to ancient Egypt. Without the Nile, Egypt would be nothing but desert, because the region receives very little rainfall. The Nile has provided Egypt with fertile land since ancient times, allowing one of the greatest civilizations of the ancient world to develop.
