General information about rivers and oceans

About 70% of the world is covered by water, and 97% of this water lies in the oceans and seas. The oceans have a major effect upon the weather, and they moderate the world’s climate. For example, water absorbs the Sun’s heat near the equator and surface currents distribute it around the earth warming the air and nearby landmasses in winter and cooling them in summer. Deep water circulation also helps distribute heat globally.

The most important rivers in Egypt

The Nile River flows from south to north through eastern Africa. It begins in the rivers that flow into Lake Victoria (located in modern-day Uganda, Tanzania, and Kenya), and empties into the Mediterranean Sea more than 6,600 kilometers (4,100 miles) to the north, making it one of the longest river in the world. The Nile River was critical to the development of ancient Egypt. In addition to Egypt, the Nile runs through or along the border of 10 other African countries, namely, Burundi, Tanzania, Rwanda, the Democratic Republic of the Congo, Kenya, Uganda, Sudan, Ethiopia, and South Sudan. Its three main tributaries are the White Nile, the Blue Nile, and the Atbara

uses

They used the river water levels to plan their calendar. Their year began in mid-July when the river flooded.

Since the soil deposits during the flooding season were black, the Egyptians called it aur, meaning the mud that gave life. It was a source of life for them because they farmed there.
