The Fertile Crescent is one of the best places to grow crop in Egypt because of its fertile soil and water supply. The Nile River is the Crescents number one water supply.Thanks to the floods the Egyptians were able to make a dry land into a land that can reproduce plant life. The Nile River is the World's longest river that reaches over 4,000 miles north from the snowcapped mountains of East Africa. The Nile River empties empties the rest of its water to the Mediterranean Sea. Much of East Africa has a rainy season that lasts from May until September. During this season the Nile swells with rain water and rushes northward with extra power. The river carries off layers of silt as it goes. Over time, much of the slit has been deposited where the Nile empties into the Meditranian Sea. There the river divides into into several branches, forming a vast fan-shaped delta. A delta is a very fertile, flat land made from silt that was left behind as a river drains into a larger body of water. The slit-filled mud was mud was filled with rich minerals that are needed for the plants to survive.
