World History - Mr. Thompson First & Last Name Vocabulary Definitions Class Hour (Circle) 1st Chapter 4, Lesson 1 Date 2nd / 4th 5th 6th 7th / 1. Nile River Valley - Located in the northeastern corner of Africa. Set in the middle of the Sahara desert, it was the home of one the world's first great civilizations, Ancient Egypt. 2. The Mediterranean Sea – This large body of water is at the mouth, or end, of the Nile River. Its name is a compound Greek word that means “Middle Earth Sea.” 3. Lake Victoria – The source, or beginning, of the Nile River. It is located 4,000 miles south of the Mediterranean in Africa’s highlands. 4. Silt - A mixture of tiny bits of black soil and rocks and was excellent for farming. It was deposited in the Nile River Valley and in the delta every year when the river overflowed. Silt allowed farmers to raise crops in the desert. 5. Delta – This triangle-shaped area is flat, fertile land made of silt left behind when the Nile empties into the Mediterranean. It is named for the triangle-shaped fourth letter of the Greek alphabet. 6. Lower and Upper Egypt - When Ancient Egyptians drew maps of their country they drew it as a lotus flower with a long stem. Lower Egypt is the flower part of the map, but is actually the “downstream” part of the Nile River; the part called the Nile Delta. Upper Egypt, the long stem part of the flower, is actually south of the delta, but is the “upriver” part of the Nile in the highlands. The names “lower” and “upper” have nothing to do with North and South on the map. 7. Flax - A plant that grew well in the Nile River Valley. When spun into thread and woven, it made a lightweight fabric called linen. 8. Irrigation - The watering of dry lands by means of streams, canals, pipes, and other human-made devices. Egyptians brought water from the Nile River directly to their farmlands. 9. Shadouf – This stone-and-wood bucket-lifting device that scooped water out of the Nile. It was another part of irrigation technology. 10. Nilometer – This invention looked like a staircase on the riverbanks, but it was actually a device for measuring the steady and predictable rise of the annual floodwaters of the Nile river.
