Why does the Nile rise?

The Nile River rises primarily due to seasonal rainfall in its upstream regions, particularly in Ethiopia and the East African highlands. During the rainy season, the increased precipitation leads to the swelling of tributaries that feed into the Nile, causing the main river to rise. Additionally, melting snow and ice from the Ethiopian highlands contribute to this rise. This annual flooding historically provided fertile soil along the riverbanks, supporting agriculture in ancient Egypt.
