Egypt's Landscape: Desert, Nile Valley & Delta

Egypt's geography is defined by the Nile River cutting through the Sahara Desert.

1. Deserts (96% of Land Area)

• Western Desert (Libyan Desert): 2/3 of country. Sand seas (Great Sand Sea), oases (Siwa, Bahariya, Farafra, Dakhla, Kharga), depressions (Qattara -133m).
• Eastern Desert (Arabian Desert): Mountainous, wadis, mineral resources (gold, phosphate), Red Sea hills.
• Sinai Peninsula: Triangular; mountains (Gebel Musa / Mt. Sinai 2,285m), desert, coral reefs.

2. Nile River Valley (The Lifeline)

• Narrow strip (5–25 km wide) + 1,000 km long.
• Floodplain (now controlled by Aswan High Dam) — fertile alluvium.
• 95% of population lives here.
• Cliffs (escarpments) border valley.

3. Nile Delta (North)

• Fan-shaped (240 km coast), 22,000 km².
• Highly fertile, intensively farmed (rice, cotton, wheat).
• Network of canals, drains, lagoons (Manzala, Burullus, Idku, Mariout).
• Subsiding + sea-level rise → existential threat.

4. Coastal Zones

• Mediterranean: Alexandria, Port Said, Rosetta. Beaches, lagoons, erosion.
• Red Sea: Hurghada, Sharm El Sheikh, Marsa Alam. Fringing coral reefs — world-class diving.

5. Notable Low Points

• Qattara Depression: -133 m — salt pans, fezzan, WWII history.
• Dead Sea Rift extension: Gulf of Suez, Gulf of Aqaba.

Egypt = Nile + Desert. Civilization clusters on the river; the desert defines its margins.
